Thanks for the review. Lots of good info!
Hey Gunter, thank you for watching and welcome to the channel! Glad I could help. Cheers. 👍
That's quite nice for the price, I own a half decent linear power supply and I wouldn't swap it BUT one of these would make a good companion for it, thanks for the review.
Hey Shaun. I think OWON with this one found a sweet spot. I think this might be a sales success... it is really good for a switching power supply and as a lot of features. I can't tell on the long run how it would behave, but for now, it looks promising. Thanks for watching and taking the time to comment, really appreciated! 👍
As always a very good and informative review! Thanks!!! Owon does make decent devices with very good performance for the price point!
Hey Markus! Thank you for your continous support! Really appreciated. I think I said already, but I think Owon is not a Rigol or Siglent, but is really the underdog here, they have nice products for the price you pay, very nice products I should say. But I saw comparations in some channels with Rigols or Siglents that cost 2 or 3 times more and offcourse if you pay more, you can get better parts... but well, what do I know... I just a enthusiast! Again, thanks for watching and nice comment! 👍
@@TechCornerTV Hi, do you know if the USB port is isolated?
Best Regards.
Thanks for the video 😎
Hi Daniel, it was my pleasure. Glad that it was helpful. Thanks for watching.
Good review. Thanks!
Hi Werner, thanks for watching!
For programmable power supplies, please test the programming part (not the manufacturer application, but actual SCPI support). KORAD for example has issues with that, their app uses some proprietary undocumented format, and the SCPI commands sent to the device can be randomly interrupted by transmissions from the device itself.
Hi, I will try to come out with some kind of test script that allow me to test the equipment without spending to much time in it, right now I don't receive a lot of power supplies for testing, but I will try in the feature to cover that part also. Thanks for watching.
Very informative video thanks.
Hi, glad it was helpful, thanks for watching.
It's important to note that the top model is also only 300w, therefore while it can provide 10A, it can only do so up to 30V. Being 300w maximum, it can only deliver up to 5A @ 60V, same as all the other cheap 60V power supplies out there.
Hi, totally right. Thanks for watching and sharing.
Addition of interesting music. Well Done!
Hey Lian, thanks for the watching and for the comment! 👍
Hello, thx for the great video!
Did you still have the version of pc software from your Video? I only find the new version without voltage sweep.
kind regards
Marc
Hi Marc, I do have installed in the computer the version, you will not believe, but the original version came in a CD that somehow I broke,while storing the power supply in the box, so, really sorry... can't help you. Thanks for watching!
Nice review but you are VERY gentle towards OWON regarding the noise production. It would have been nice to have a sound sample without always available background music. I need a 60V5A psu for charging a battery bank controlled by a bms that gets the chance to balance the cells at low power input.
72dB to me sounds like a fighter jet flying by in the room.
Otherwise I would have pulled the plug immediately and orederen one of these...
Hi! Ok, I understand what you mean, since I was testing sound, the background music shouldn't be there... this feedback is precious for future videos. Thanks. What I can do help you is, cut this part of the original recording feed, it took quite a few minutes and send you by wetransfer without any editing. Just send me a e-mail trought the business conctact on the channel about page. Thanks for watching and your input. 👍
That being said, you can mod that yourself with a low noise fan... Or maybe even they can fix it with a firmware update (still would go with a low noise fan though). As for the ripple, that is something you can probably also fix with a few small mods (i.e. some resistors and some caps).
I am RETURNING mine straight away... since I really wanted something that looked nice and modern on my bench I picked this one hoping at least on 1 to 4.5V 1A range it would be quiet.... but NO.
It's like a Philips Silence series hair dryer at minimum... it can DRIVE YOU ABSOLUTELY INSANE when you're troubleshooting small devices, not only for the noise but also because it blows DEAD COLD AIR from the sides, my hands went numb in a minute with it on.
And I spent 15 minutes trying to figure out how to program it since the manual was mistakenly saying you need to push the wheel... when in reality you had to push AND HOLD.
I also bought a bench multimeter from Owon which I thought to keep but I am returning it as well. All it was required for the multimeter was to measure Ohm decently enough and voltage with two decimal precision. Guess what? It is WHINING like crazy... it seems like an "open air" function generator set at 15kHz.
Absolutely APPALLED by the poor usability of Owon's tools.
wow very nice!
Hey Tron, yeah, I think so, propably a sales hit... thanks for watching and coming by again! 👍 New giveaway is running, take a look!
Very nice design. But fan makes too much noise. The temperature-dependent fan speed control is incorrect.
Hi! I loved this power supply, for a switch power supply is pretty good. There is some "issues" but nothing major to be honest. Regarding the fan, I have the Rigol DP832 as my main power supply and as soon you power it on, it makes a huge noise with the fan, way more than this small Owon. When you take the SPE to the max, the fan can get quite noisy, yes it is true, but it depends on the charge you apply to it, if you're working with 5V and 1A or less, is very acceptable. As I said, it is a good "package" full of features for more or less $120. Off course all I said here is my opinion and experience, yours might be tottally different, even the device you got might behave in a different way. I trully appreciate your comment and thanks for watching . 👍
@@TechCornerTV Maybe I have got defective one. Fan still running at almost full speed.
I must have got a Friday model. Mine has 2.3v spikes on 12v output with no load. Ok for charging car batteries, but not much use for electronics.
Hi, that's a lot... I don't experienced such spikes. But I will run it on an oscilloscope again just to check. Thanks for your input and watching.
it's hard when I wear headsets for the music to keep getting super loud, then I lower sound, then need to put sound back up for voice. it would be better to just keep music at lowest subtle volume and same level at all times otherwise there is need to change volume all through video
Hi, living and learning. You're right, my latest videos are better. Those the music was in fact a bit high, sorry for that. Thanks for watching 👍
So, are you going to ignore the 702mV oscilation around 25:10? (step frame by frame with . and ,). It looks horrible!
Hi! Sure I will, considering all the switching fonts I saw up until now, this is by far the best. It is perfect, not at all, but it is a hell of a power supply for $100. I can't even say if that oscillation wasn't cause by me touching the cables or something else. I understand your concern, specially in mV projects, that can be serious, but for that kind of work you should use something better, again this is a programmable power supply (connectable to the PC) with LCD for $100, we have a lot, but can't have it all for this price range. But what you get is enough for me! Off course this is only my opinion, I'm not even a professional in electronics, so it worths what it worths.... anyway, thanks a lot for your comment and the time spend watching the video, really appreciated! 👍
@@TechCornerTV Sorry but having ripple+noise+whatever that makes the signal oscillate so much, adding up to 500mV or 702mV+, can result in the destruction of some component under test/load. I wouldn't test any PC/PCB component with this unit.
Hello
Could I ask you to send me a photo of the mosfets area because I had a short circuit and burned the resistors and I can't read it.
Hello, sorry for the delay, but it's been hard on time, I will try to do that as soon it is possible. Thanks for watching.
The power supply is very similar to the KiPRiM DC310S. Only the color seems to be different.
Damn... you're right! But I can't find it on Aliexpress and only found some for sale on Amazon, can«t tell who is manufacturing for who... nice catch, thanks for sharing. Anyway, is a nice power supply, I liked it.
That's true. During my research for power supplys I also see both the owon and Kiprim. I wondered if they have the same internals and just a different color. Did you find out, which one is the original manufacturer, or if one has a weaker performance?
I want to buy one, but I am not sure which one is better.
I bought the Kiprim, I try to download the Owon software from official page without success.
I want to try it.
Best Regards.
Seems to be similar to VOLTCRAFT DSP-3005V SE 30V/5A power supply, distributed through Voelkner (89€, incl. shipping) and Conrad (99€ incl. shipping)
Will this do constant voltage and current.? Ta
Hi, not using right now (packed because I'm moving), but I think it does. Thanks for watching!
Tell me why the power supply without load shows a current of 27mA?
Hi Sergey, after your comment I went to unpack again the power supply and tested it. And you're right, as soon as you turn the channel on (not power on, power on and channel off gives 0V/0A), even without anything connected to it, it shows 0.022A in the display. I can't explain why but I will ask the marketing at Owon if they can connect me to a tech team that can explain why that happens, it will be nice if I can get the answer from them. Thanks for watching and for your comment. 👍
Hi,
I have seen this issue also in some other reviews of Chinese power supplys, like Topshak (I think) for example. Did you get any feedback from the manufacturer yet? I think it's quite important to know, if this "just" an offset error which can be corrected with a firmware update, or if it's just a bad general measuring precision. Especially for driving an LED in CC mode at just about 20 mA. Did you try to use the power supply in CC mode at such low current values an see if the control loop behaves normal an maybe test the current precision with a multimeter?
Thanks in advance!
@@TechCornerTV Hi, please tell me, is there any news on my question?
@@SegaKHV Hello! No not really... sorry!
@@SegaKHV Yes, it's possible to calibrate it. Take a look here: ruclips.net/video/8DgoMLwZc9A/видео.html (at 36m:30s). But beware, the overcurrent protection seems to be off during calibration, as mjlorton experienced...

Hi, I notice that too, I think that might be a construction issue, that the current consumed by some part of the control is being registered on the voltage meter. Other than that, is a darn pretty good power supply! Thanks for watching!
the music is very distracting for a very good review
Hi, during the life of the channel, I tested several things to make the videos "different", some worked, some didn't. This one, was one the things I currently don't have in my videos. Music is currently reserved for 30secs intro and 20secs feature highlights. Thanks for the input and for watching!
esse ingles portugues nao engana ninguem :P
Olá! Nem é para tentar, vê lá se na descrição do vídeo não tens o link para a versão em PT.... obrigado por assistires e comentares 👍
Please! Leave out that music. very annoying!
There is still something wrong with your voice recording. It sounds like you have some kind of compression, rather unpleasant.
I find the high frequency noise level unacceptably high.
Cheaper OWON models have more or less the same problem.
It is not clear if it is differential or common mode noise.
Therefore I strongly prefer linear power supplies on my benchtop.
Furthermore 72dB acoustical noise is unacceptable!
Still a useful review, even if we don't agree.
Hey Joop, I only have about 30 videos by this time, I experiment a little in some of them to see what works and what don't, I agree, the music in this one was a bit over the top. Regarding the noise, I have also a Rigol DP832 power supply (that I love) but from the moment I power it on, it starts making a huge fan noise... at least the Owon only speed up when the level reaches a certain point, it's loud but even so not so loud as some other devices I've seen. But for a switching power supply (no linear) I think is pretty good. Let's agree to disagree 😁 but I really give value to all comments and particulary yours, you always justify your opinion and give me useful feedback, thanks for that. Which power supplies do you use? Thanks for watching! 👍
0.000 how to solve
I'm not sure if you can...
У нього немає ocp тригерного захисту відключення по перевищенню струму тільки обмеження.Думаю це погано в такомуц класі.
Ok, thanks for watching! 👍
No mains switch on the front panel? That will put off most buyers. School boy design error! 🤦♂️
Hi Chris, yeah, that would be nice. Thanks for watching!
@@TechCornerTV I'd say essential if it's used in a stack like the vast majority of bench PSUs are 👍
Compare your output noise level measurements to this guy's results ruclips.net/video/bRWdQESwXMA/видео.html and you'll think you'd tested two different PSUs. Weird!
Hello! Sorry for late reply, house move and vacations. "You get what you pay for", this how I see everything I test. I have a almost $500 Rigol linear power supply, really nice that also have a spike on power up, so for the price you pay for this one and consideing it is a switching power supply, I still mantain my opinion that is one of the best in terms of features and quality "for the price range". There is always those can see the cup half full or half empty. I more to the first ones... 😁 but that's the cool part of YT, you can see different opinions and create your own! Thanks for sharing and for watching!
50 dB with no-load is absolutely unacceptable noise floor. You should have made your video without background music.
I am returning mine for this reason and the fact that it unnecessarily blows dead cold air from the sides... making my work almost impossible in my 15°C place. The bench multimeter from this brand wasn't any better... it whined like crazy, beeps like a lion with no way of turning it down. All it was required to do was to measure some Ohm and some Voltage with two decimal precision.
Not all Chinese maker are this bad... Uni-T makes wonderful multimeters, their bottom range function generator is equally awesome for the price... I don't know if it's just bad luck but I am appalled by Owon tools' usability.
Hi Tobias, sorry to ear that. Is a pitty your experience. I have mine for some time and it works well. But I understand what you're saying, I hope you get to solve your problems with a different equipment. Wish you the best! Thanks for watching!
I can not listen to that! Too many ohhh, ehhh, mhhhh. Bad sound quality.
Why you show a ripple/noise measurement, if you can not measure it accurately?! This makes no sense in my opinion.
Hello! Sorry for late reply, house move and vacations. Well this video has a bit of time, nowadays I try to take those of in editing. In my previous lab I had a lot of noise during the day, so I recorded at night, mostly after 0:00am and sometimes the brain don't work as expected 😁 and those ehhh.... are the time needed to put the ideas in place, mainly because english is not my natural language, no excuses here, just so you can understand. I moved this month to a new house, a new 20sqm electronics lab instead of 2 and is on a basement where I can record at any hour, so I expect to have less of those ehh... in new videos! Thanks for sharing and watching!
too small to be any good
Hi, you have to compare it with switching power supplies, not linear. For a switching power supply is pretty decent. My biggest complain is the power button in the back, doesn't make any sense. Thanks for watching.
🤢
Thanks for watching! 👍
Again with the annoying music! 👎 Unsubscribed.
Hey again, sorry to see you go. I explained the music thing in the message of the Loto video. See'ya around. Stay safe and thanks for your feedback and watch time. Cheers. 🤜🤛
