Cheap 300W workbench variable power supply. Can it deliver and charge lithium batteries?
HTML-код
- Опубликовано: 18 июн 2021
- I ordered a new upgrade for my workbench, a new variable power supply 0-60V, 5A. It can do CC and CV and is perfect for charging all kind of batteries. It seems like a good unit but the knobs are terrible and setting the voltage correctly is a bit fiddly (at least at the beginning).

Thanks for all your comments here about the Bluetti video. It's been fixed now. I deleted the 'angry' part of this video here and also flagged the Bluetti video now as a 'commercial vid'.
I need to get better about watching your videos as soon as they come out. I missed out on an angry rant???
Hello sir!!! I need to top balance my lifePO4 cells but I have cheaper lifePO4 charger 14.6V10a how can I archive this while my four cells rated voltage is 3.2V
one thing you need to learn, for your own health and sanity, you need to learn how to ignore comments like that, talking as a streamer who have to deal with that live. 99% don't understand the rules about doing paid promotions and the consequences if you do without disclosure. Starting you video "yelling" at idiots will scare away new viewers. One video with thumbs down won't ruin your stats with the rate you put out videos. great videos btw
Yep, I know. Sometimes it just gets me 😠.
I'm good now 🍺
@@OffGridGarageAustralia it gets to us all at some point and it's okay, my channel had tons of videos, but I burned out and had enough, so everything was deleted by me, that was millions of views gone including the toxic comments and I felt a relief from it, just don't want to see you at that point. It's also why is a great idea to add off-days between videos. As a one man band, is easy to burn yourself out because of pressure to produce videos, the comment section and all the other stuff that's included in this RUclips game
Man, even when you are angry you are enjoyable! Love your uniqueness! Haven’t seen your review about blue Eti but I will go ahead and look for it!
Hahaha, thanks!
Keep up the great work, Andy! You inspire a lot of us, educate us and make us laugh. Don't let others ever make you think otherwise.
Thank you!
No one makes me watch a video - I watch because they are interesting or informative, or both - and Andy, you go to great lengths to make your videos both. Much appreciated! Keep up the good work.
Thanks Ken!
Don't let the trolls get to you they're only here for entertainment for your loyal viewers 👍🙄😁🤪
Hi Andy, I watched the previous video, I was very thorough, I have to admit I looked for the "includes paid for content" banner but there was none, so knowing you, I trusted your integrity and knew it wasn't, you were just doing a detailed experience/review, I will add however if you were given the item for free it would be best to let people know this to be completely transparent, as getting something without paying for it can be seen as being a sponsored review as you got something without paying. Just my point of view, I always enjoy your content, and can tell the work you put into them, quite a bit of editing too. All the best from UK 👍
Thank you.
It was a good video and I listened and understood. Glad you have vented. I like your stuff keep helping me understand more.
All good 🍺
Nicht ärgern, Andy! Dazu sind deine Videos zu gut und sehr lehrreich.
Liebe Grüße aus der alten Heimat
I like your channel that's why I am watching I find it very interesting thank you Andy👍
Thank you both.
Hey Andy, I didn't watch the Bluetti vid because it wasn't of interest to me (much prefer the DIY approach..) but I def don't think you need to get to worked up about the keyboard warriors, just treat them with the respect the deserve...
@marthale7 you said to block those people and you said pay them no mind, So which is it? Personally I think they should just be ignored, blocking users from further comments is being a big baby.
100% with you. We need respect each other. And have more confidence also.
Thanks. Exactly be nice to reach other.
@@OffGridGarageAustralia 👍 (Please read my comment in floating video, i think you will like it and give you another option to top balance, I hope you can comment what do you think about it)
Give em hell. They deserve it. Love your efforts. Keep up the great work.
Some of the people that watch youtube ( remember only some ) like to find creators that have shall we say a volatile
personality. Lots of the time when someone is intense about a subject they are also volatile. When these people find
that channel they pepper it with hate comments to invoke a reaction. A reaction is what they are looking for and which
you have supplied. Your real viewers know the difference between a salesmen and a reviewer. Cool off , have a beer
and carry on. Take care , we love your channel. P.S. try to keep the rant videos to 5 min and under it plays better.
Had a 🍺. It helped 😊
I have had a Bluetti, same one, here in the US for a year now, it's mainly used while boondocking in our travel trailer and I love it. You gave it a glowing review, not because you were sponsored or paid but because it is a great, simple piece of kit, it's plug and play, it does what it says on the box. Your review was great and I agree with all you said. Keep up the good work. ( BTW, Warsteiner is my beer of choice.) ☀️😁👍
Thank you for your feedback, Jonathan.
Warsteiner or a very nice beer. Not even sure if we can get this down here...
Thanks Andy, I appreciate all your videos and sharing of your devices and knowledge. (Don’t let a few negative comments get you down).
Thanks Dick. Haven't gotten to your email yet... 😊
I am similar position. I have a couple of diy linear power supplies I built including one from Tafe days. I have been on the lookout for a new switch mode benchtop supply. Thanks for this experience.
Thanks, Jason! Always appreciate your comments.
Even I'm not in your country, I always watching your videos, because i am happy 😊 its interesting to me, specially your solar off grid setup... Keep always sharing your knowledge andy, its helps a lot us!! GBU..,🙏🙏
Thank you very much!
I watched and enjoyed the video in question, even though I watch your video's for the DIY factor and would never buy a prebuilt system. THANK YOU for your video's and THANK YOU for venting when you need to :)
061921/1443h PST 🇺🇸 Appreciate your sentiments. There’s immense amount of satisfaction and pride when a functional device is built by self and enjoys the result.Thanks and 73s…
Thank you very much for your feedback!
Andy, I've had two of these units for several years (under a different rebadged brand) in my electronics/robotics workshop (in the UK) - the 30V/10A version. They are cheap but reliable (and I've never heard the fan turn on). They are available next-day in UK from Amazon. I have even used them for a PHEV BMU reset! (Sure you can guess why). Anyway I've been following you from early PHEV voltage drop days-your stuff is always watchable and informative. All the best from broken cloud, slightly warm southern Scotland.
Thanks for sharing, Jonathon. That's good to know.
The PHEV battery reset feature... The good old days 😉
Hi Andy , don’t let a few people get to you. I really look forward to seeing your videos,they are the first ones I watch, thank you and keep up the great content any humour.
Thankyou very much William! Appreciate your feedback 😃
You do you, I enjoy and appreciate your content!
Thank you Greg.
Andy … I love and appreciate your videos…. You candid approach to the haters had me chuckling away …. Keep up the good work 👍👍👍😁
Hahaha, had to let off soem steam 🍺 Thank you.
lovin the sound effects buddy i cacked my self
I appreciate and learn a lot from your videos. You inspired me to get going with my own solar garage. I just got 5 430W panels, a 48V battery and I may be getting a 12KW Growatt inverter/controller/charger. Heck I might even make a video about it. Don't mind the poo peddlers. The keyboard commandos have nothing better to do.
Thanks for the feedback and sharing. Wow, that sounds like a great system you're building there. I looked at the Growatt units and they seem to be great!
From Wichita Kansas, I thoroughly enjoy your videos!!! Thanks for your channel.
Thank you very much, John. I appreciate your feedback!
Excellent work Andy. Ignore the haters! Thank you for your work and efforts, it is extremely appreciated. Iv got the 30V 10A variant of that power supply. Used it to successfully resuscitate/desulphate my 4x 200Ah AGM batteries. Unfortunately the capacity improvement was short lived. Saving up to eventually replace my old crap batteries with 16S 280Ah LiFePO4 😁
Thank you.
You go Andy! I love your video's , keep up the good work,
Thank you! 🌙
With these modern supplies, you are supposed to set your constant voltage level with no load and set you constant current level with the leads shorted together. This approach simplifies your setup a little.
You going to love that power supply I got one just like it except for it's the 305 which is 30 volts it works great man especially for designing and testing batteries
Had it running for 1h yesterday on 60V and 5A and charged the battery. The fan turned on and off as it should and it worked great!
Thank you for the review.
You're most welcome.
I found your review of the Bluetti Power Station useful. Most of the other reviews are of the Bluetti under a 100-120V AC 60Hz load. On paper the max efficiency (>70 load) is 88% (110-120Vac) and 90% (220-240Vac). A real-world review of how the product actually performs under higher voltage at 50Hz was helpful. I've been waiting for a local review of this product for some time. Thank you.
Thank you very much Mark. Appreciate your feedback and comment!
Thank you for sharing
I love watching your videos, including that bluetti one, even though other channels have reviewed it I like to see the different opinions and
thoughts on the same device. I own a bluetti ac200. Great device but their solar panels suck (have had 2 fail within a few months) Those negative nellies don't have to watch the vidoes, they don't think before they write, just ignore them.
Your channel is still my favorite of all.
Thank you very much!
I love your videos dont change. I love your reviews & your content its also about solar and batteries :) have an awesome day sorry replied before the end I am sure its as awesome as all your videos
Thanks David, much appreciated!
Just what i was looking for to learn about my NEW supply too !!! THANKS ANDY !!!
Andy, don’t let them get to you! Haters will hate. Your a good man and those of us that have watched your channels for a long time know that. Personally I found your review informative even though I am not an Australian consumer.
Thanks Harry, much appreciated!
I got the same bench PSU (different brand) and it worked great for charging my 48v banks. Also for pre-charging the Caps in inverters. I left it charging a leadacid 48v bank, for two days. The voltage setting didn't drift at all.
Ah great to hear, I was wondering about this. My old one drifted a lot when it got warm so I had to adjust the voltage all the time to no overcharge my AGMs.
061921/1403h PST 🇺🇸/ 062021/0720h Brisbane 🇦🇺. Good day, Andy. Thanks for the demo on WANPTEK 60V05A PSU. I found them to be simple, light weight and small foot print unit with greater working environment. I had WANPTEK 30V10A for few years, until I murdered it by connecting to opposite polarity. The glass fuse didn’t blow, but shorted the MOSFETs. I will work on it. Then I got WANPTEK DPS30-10U. That unit is even better than the previous one.
There are several variants of this PSU. Please view them. 90 days for the shipment delivery? Err no comments.
Now a lil bit of sentiments:
People talk, people also make illogical comments and decisions, on others. Circus is enjoyable with the accompaniment of Clowns. You got the gist, I suppose.
A full can of Oettinger and Rick Braun’s Trumpet, will compensate the agony.
I enjoy, I learn and look forward to your researches and results. Please continue your scientific endeavor. We look forward to viewing your hard work on the screen. Take care and be safe. 73s…
Great video! I've enjoyed watching and learning for some time. I have a similar 60V/5A ps. ($90 on Amazon) and yep, its tiny just like yours. If I may though...my understanding was, you first set the Amps by powering up and shorting the leads, then dial in your target Amps while the volts are turned low(3-5V) then turn off the unit, un-short, then turn on and ramp up to your desired volts, then attach your load. (In this case a batt) I'm remembering somewhere that said once you set your target V and A, it's not a good idea to adjust the Amps while the load (batt) is attached. I may be remembering it wrong, but I recall it was a big no no, especially for battery charging. I humbly stand corrected if in fact, this is mis-information and a non issue. Again, love watching and learning along with you!
Thank you Tyler. The usability of the power supply get better over time once you get the hang of it and leran how it works. I really like it.
Andy, das war ein tolles Video . Lass dich nicht ärgern
Danke Dir. Alles gut, machmal muss man mal Dampf ablassen 😉
Bro. Don’t worries about people who are say. Your video making good and very good ideas 👍🏻
Thank, Michael!
Fair and honest information keep up the good work and do your own thing.there are always nay sayers that's why they have different. Channels I personally love your information and hanging out in the garage with you thumbs ☝
Thank you Will!
Nice. I bought the same toy. Very convenient
As I remember me to my first DC power supply in the 70s, 2x 30V 6A, heavy device 20kg .....
Yep, mine was like 8kg and could only deliver 2A max. Big transformer inside. This one, 5 times the power and weighs nothing 😃
Looks like a decent power supply. I've had a 0-30V, 0-10A for a few years now and recently bought a 0-60V,0-5A also now that I'm occasionally playing with 48V setups. It's a different brand, but the banana plugs are a weak point on it too.
Thumbs up for your videos. I have one similar DC power supply but for range 0-30V and 0-10A. It's a very basic power supply and yes the adjustment of volt and ampere is a bit of a little hassle. The most negative issue I have with the power supply is that the display or the build in voltmeter is not reliable. I get different values (Volt) from DC power supply and my new UNI-T multimeter measuring instrument.
Thank you.
I checked both volats and amps a few times and they seemed to match with the Uni-T. Had the PSU running for over 1h yesterday and chargig the big battery and also no voltage drift even the fan came on and cooled. Seems to be good so far.
I had no issue with your Bluetti video, I got the point and didn't think there was any conflict of interest in it. You were equally critical and enthusiastic, so I don't understand the hate you might receive.
For charging, I use an iCharge X8 fed from an old telecom PSU which I think is a bit over 60V and 800W.
Thanks Bob, much appreciated!
Yes, the iCharge is on my list of devices I want to check out in the future.
they are called trolls for a reason.....and to expect reason from them is useless. as for the rest of us keep doing what you do Andy that is why we watch.
Thanks heaps Arnold
Hi, whenever I use a PSU to charge batteries I use a 20A Schottky diode in circuit, that will protect your PSU if the one fitted on the output is a bit weedy,
I enjoy watching all of your videos. It's a shame some people don't just appreciate what content creators do. Glad you got to vent. Hopefully you just ignore future ignorant comments and don't let the small minority upset you.
Thank you Sean. All good and under control again 😊🍺
Hey Andy, dont worry about the Haters! They are Everywhere!!!! It was a great review PERIOD!!! Side note: A paid review of a free product and a non paid review of a free product are one in the same in RUclips community guidelines and the box has to be checked for the thingy to show up on everyones screen letting them know its a "paid review". Keep up the Great work you do on this channel!!💥🤘
Thanks Joe. Appreciate your feedback. I have now updated the video accordingly to the RUclips regulations.
@@OffGridGarageAustralia Just looking out for #1!💥🤘
Hi Andy, thanks for all the great videos. Don't get so upset it's not worth it. Greetings from Holland!
All good, 🍺 helped 😂
Dramatically fantastic video, dc power supply is excellent way to check and charge batteries, I am an electronic amateur and prefer to use dc power supply than other chargers.
Thanks again.
Greetings from Saudi Arabia.
Thank you.
You are so clever Andy. I hope your wife appreciates you as much as we do.
Thanks... haven't seen her for a while. I should go inside more often... 😂
In my mind… if you got it for free… then that means you got paid in merchandise instead of cash so at the end of the day you still got paid!
Just saying!!
Yes, its not only in your mind its part of the RUclips agreement. If you get something for free from a company, you have to check a box as a "paid promotion" even tho you dont, or didnt get paid. The product is considered "payment". It also depends on your location.
I have upgraded the Bluetti video now as per RUclips standards. Thanks for pointing this out.
Hi Andy, please keep up the nice work and ignore poorly behaved people. I think it's much better to get a RD6012 or RD6018 and 2-3 used 450w HP server PSU (series to make 27-40VDC) to build as a power supply or charger. Far more usable and reliable than cheaply made staff. Just like don't charge the $1000 mobile with a dollar shop charger. Cheers from WA
Thank you, all good 😉
I looked in to the RD60XX versions but I dodn't want to buy a separate PS and then put this all in a case. I also don't wanted to press buttons and change settiings just for a wuick test. I wanted a quicky and easy solution for quickly testing electronics and batteries.
As a very wise you-tuber once said, 'haters will haters, easy to say but sometimes hard to ignore, thanks for sharing!
I am not fond of autocorrect, 'haters will hate'
Thanks, it's hard to ignore sometimes.
I ran across your video while researching a power supply for small electronics projects and thought I'd send what I ended up getting because you seem excited by what you have :)
Google Miniware power supply. It is a 300W 0-30v, 10A supply, but the kicker is it is about the size of a deck of playing cards, lol. Powered by USB PD or DC voltage. A bit spendy, but so far, it is fantastic! I've been reviving batteries all morning :). (Not trying to shill, but I am really impressed by their stuff)
Thanks for sharing. I will have a look. I'm keen to see if they make a 60V version as well...
Could you use a resistor between the posts to dissipate the residual voltage and allow your voltage adjustments to be closer to real-time?
You probably could but would have the load of this resistor all the time. It's not too bad after using it for a few days...
I would recommend getting a power supply with an enable output button. You don't have to adjust the voltage and current with the load connected.
There exists a 60V 5A version with those features.
Often these units allow shorting the wires to set the current, before applying to load
You tell em Andy !!!! Negative never did anything wowsers. We love your video's.
Thank you very much!
Hi Andy...... don't take it so personal, there´s lot of trolls over the internet. Not worthy to have a "bad time" because of them. Love your videos, even if I'm at the opposite part of the world (our feet are facing each other....) Take a beer (not as nice as here in Spain) and enjoy. And congratulations for your channel. Thanks for your videos and your effort, letting us to share your experiences. THANKSSSSSSSS
HAHA love it I will just wait 10 seconds for you to turn off now. Andy, more SPAT, Keep up the good work I for one have subscribed and enjoy your vids and sense of humor. Rather change the Banana jack that cut the part on the power supply?
Andy don't worry about what they say I enjoy watching your video's I am in South Africa and think they are great and extremely interesting and thank you once again
Have a Beer and relax
@@vickipps6821 I did!
Interestingly many of those power supplies with dual (Course and Fine) knobs, have a different adjustment range for the Fine depending on the setting for the Course knob. So if the Course is set at 5v, then the Fine may adjust 0.25v. But if the course is set at 60v, you may find the Fine has a 1v range.
I have a 30v 30A bench supply, and it has a 10 turn pot for the voltage. It's really good to use as opposed to the Course/Fine setting on the one I have like yours.
These are the best types of supply to do testing of specific settings for a BMS.
Thanks Paul. Yeah, this one adjusted as well depending on the voltage. I found this out last night 😉
❤ echoing some other comments, your videos are really good. Ignore the trolls and ignoramuses. I don’t necessarily agree with all of your conclusions or assertions, but I ALWAYS appreciate the effort that you put into your videos, and the content you share with us very candidly. Keep it up and don’t be discouraged...
Thank you very much!
Hi Andy,that power supply is just what I need,too replace my home built supply that is now 37 year young and how has a few faults so for the price delivered to Australia that sounds like a good buy. I think a pull down video of the bench power supply would be of great ...
Hey, you must have had the same old one I had 😂
Using it for a few days now and it's been great. Exactly what I needed...
don't worry what they say, just continue as usual
Will do, thank you!
Don't be angry Andy only human !
You sir are awesome! Don't let the haters take you out of your space! EF 'em!
All good again, thank you!
How do you know the correct Voltage/Current for the different batteries/battery technologies? I have the same power supply.
Hi Andy im from South Africa I am 81 years young I also still get on to the roof to put my solar up a lot of my so called friend tell me im wasting my time But But they come to me to watch rugby when the light go out......there will always be negative morons you just keep going after all you enjoy what you doing you just crack a beer I'll be with you ......from South Africa till next video
Thank you William. Much appreciated!
I have a couple of identically looking power supplies I got from Amazon. They apparently just make a custom label for other companies, mine says "Eventek". Mine are model KPS3010D 0-30V 0-10A.
They show up under many brands, same chinese factory making them, I guess.
Don’t worry bout the haters. I watch cos I think I might learn something. Would love for a few drop replacement companies to pay you to review some batteries. Voltax, Enercore, Itechworld.
I guess, there will be some more reviews in the future. Maybe...
Thank you.
I have a quite similar model. Unfortunately I selected the 30V 10A model. In hindsight I should have selected the 60V 5A model as you did.
And btw.: Friends 🍺🤜🤛
Thank you! 🍺
I would have bought a 60V and 10A but as you said, it's 30V and 10A or 60V and 5A, so...
Those power supplies are cheap and built to the price but they definitely get the job done. I have a few (10) I ordered for the school I teach at for the electronics class and the first thing I had the class do was take them apart and replace the output terminals and also add 10 turn pots to replace the course knobs. We swapped out the volt and amp meters with 5 digit ones. We also beefed up the wire going from the circuit board to the output terminal to prevent voltage drop and they are now really decent units and you would not even be able to tell that they were modified other than by using them since we used green voltmeters and the 10 turn pots making the fine adjustment kinda pointless.
Thanks for sharing. These are good suggestions and I'll look into this. It's not hard to improve these things.
Why did you go 5 digit with the meters? Do you need that accuracy?
@@OffGridGarageAustralia It made adjustments easier to see without a meter connected when you upgrade the unit to a 10 turn potentiometer. In the electronics class the students build a lot of circuits that need a fairly accurate voltage reference to help prove that the math works when they are starting out and are new to electronics. It also comes in handy when you need to diagnose voltage or current fluxuations coming from the power input side of the circuit without hooking up an oscilliscope since the 5 digit meters were a bit more sensative to fluctuations.
can you change the fine-tune knobs to multi-turn pots?
Yes, someone mentioned this here in the comment, so I will probably do this as well in the future. It's not as bad any more once you get used to it...
Hey just ignore the I love you job and am slowly learn about Lithium batteries so that my next battery bank can be lithium
hi andy, just ignore those keyboard warrior , your video is full of knowledge sharing and fun, thank you andy
Thank you very much!
The Fine controls appear to have a range of around 10% of where the Coarse control is set.
Australia isn't the only place with slow delivery. I have a package coming from one of Banggood's US warehouses. It left that warehouse (at least got a departure scan) 11 days ago and the US Postal Service is still waiting for the package.
Yep, the fine knob's range is changing depending on what voltage or amps you have set with the coarse knob. Makes sense. It's not too bad once you get used to it.
I've been charging my tool batteries used for electric bikes with a variable DC supply. I wonder if balancing is still employed.
There are some good variable PSU buck/boost modules available, eg ZK-4KX, working off up to 30v DC, 3 to 4 Amp. Cost around 11 AUD or $8.25.
Yes, there is some good stuff out there, just need to conenct your own power supply and put it in a nice case. I went down the path of just buying one this time. It works well so far.
You are the Solar Guru to many solar fanboys when they saw the Bluetti right away they suspected their messiah has sold out. I didnt criticize you just asked why you picked the that Solar Generator. .
All good, thank you!
I've had the same brand for several years. After about 3 or 4 it started to drift and now the voltage jumps around almost an entire volt when I set it to something. Does yours do this by now?
Andy... I personally will apologize for all those idiots. People, man!
Thank you very much. You don;'t have to. It's all good, just need to let of some steam. Thanks again 😊
On a bench power supply I really like the ones with an output enable/disable switch separate from the power switch. Adjusting that new one seems quite annoying.
It gets better once you're used to how it works. It's a bit fiddly but not too bad after a few days now.
Can you measure the efficiency of the power supply when using it to charge a 12V battery at 10A?
The fine buttons must be as a ratio or % of the course?
Ignore the trolls Andy, If you don't feed them they will go elsewhere for food lol. I have seen the Buetti before but until your video did not know they were now available in Australia and since going to check it out i am now aware of the sunpower foldout solar panels they have which look pretty decent.
Thank you.
Hey Andy, an American here. I want to start by saying that this is my favorite RUclips channel and is the only video that I wait for and am disappointed when there isn't a new one to watch. So there's that. Don't let the keyboard cowboys get you down. I'd say there are a ton more fans out here than not.
I have a product similar to the Bluetti but have I've only tested it but haven't used it. It's not near as powerful though. 62Ah, I think. I bought it for hurricane season.
Remember that this criticism is coming from a fan. In the future, I'd suggest that you say up front that you got a product for free. I don't think you did with the Bluetti. I don't ever remember hearing that disclaimer. That would probably solve your problem. If it doesn't, they can't say you weren't honest. I believe you are an honest guy that enjoys putting out video as much as I enjoy watching them. So I never thought you had any ulterior motive other than putting out great videos.
Keep up the good work and don't let them get you down.
One more thing. The comments seem to be saying the P/S is not very good. Maybe a company will offer a very good one for review. Hahahahahahahahaha!
Thanks a lot, Porter. I've updated the Bluetti video by now and marked is a 'commercial video', so that's that out of the way.
Thanks for your kind comment here, really appreciate that sort of constructive feedback.
I wouldn't say no, to a high spec power supply to check out 😂😂😂
In my Honest (and Humble) Opinion (IMHO) a decent variable DC power supply is a must for anyone who is going to work with Batteries of any kind for essential power.
Absolutely, the old one was just not up to date any more...
I've been tryn to figure out how to get a waterproof groomet with thread in there.. im assuming there's no room for hands?
Keep up the good work Andy. There are trolls everywhere these days I’m afraid.
Calibrate a few more sun aligners and all will be forgotten ;-)
Thank you. Some 🍺 helped 😊
Does your charger still work? Mine just broke after working for about 30hrs
Hahahaha mate, rip it up them! Love your videos, you do well
Thanks Craig!
Hi, I need some advice. I just bought a Power Supply Kococater SPPS-S605: 60V - 5Am, pretty similar to the on the video. Firstable I am not an engineer but I am trying to emule a device with this PS. I want to use from 1 to 50V and from 1 to 35mA. I tried and set up to 20V and 5mA, but when it was used, the display showed: V:4.8 (it was moving but just reached 5V, and the Amper value did not move, it stayed on 5mA, this is the value I wanted). Here comes my question: What should I do and order to get this measurements: from 1 to 50V and from 1 to 35mA (I need to hold the voltage without changing the miliampers). Thanks.
I want to introduce a new holiday, Low Amps Day , that will be our off gridders national day in the south, take out the bbq and 🍺🍺🍺 and celebrate with me, Ben ZA !!!
Oh, yes, I've got this holiday daily for some weeks now. I'f I get 10A peak, I'm cracking a 🍺
Hey, nice video. I was wondering if you have an idea for my situation. I have a shop where I do electrical work on vehicles. Now from time to time the vehicle battery will drain because I work on it for more than a day or so. So I'm looking for a 12v power supply where I can hook up the vehicle so they never drain while working on them. I might as well use some of the power supply to power some probetesters around the shop. Since it's all under the same circuit. I'm not looking though to set rules each and every time I hook up the vehicle. I want it to be a quick thing. On & off. Technically I'm not even charging the battery I'm just maintaining a 12 volt flow. Please let me know if you have any ideas what I can do. Thanks 🙏🏻
Don't let the trolls upset you. Keep up the great work
I'm good, had some 🍺
What is the efficiency of that power supply when charging a 12V LiFePo4 at 10A?
