Decent build quality for the price. Power supply with those specs for less than $100 shipped sounds like a great deal.
Nice video about a potentially very useful product. Thanks. The build quality looks good, but it would have been nice if you had put on at least 50% of the maximum load and checked to see if the unit would work, and if so, whether it could dissipate the waste heat over a reasonable period of time. You didn't really show the heat sink, but the few glimpses appeared sort of flimsy for a converter which is rated to output 360 Watts, which probably would translate into 70+ Watts of heat dissipated in the unit.
I thought the exact same thing watching the video. He could have droved it at 100% It's not a real review if you dont test the equipment to their stated limits.
I would have liked to see a scope shot of the startup transient, at different voltages, and maybe see how fast is the CV-CC transition.
But it seems like a reasonable power supply.
I'll make sure to test on the next power supply. Thanks
It took about 2 seconds from CV to CC. I don't know whether that's a good or bad number for this kind of power supply but I burned 3 LED because of this slow transition speed.
10:13 my OCD is not able to tolerate those to-220 mounted in that way.
Ty, loved the video and the detail I'm researching designing my own and gaining a lot of new knowledge
I've got a couple of other power supplies to test. Hopefully they will have some useful design aspects.
That's a good unit for the money. Thanks for the review Steve. Cheers!!
Thanks Jim :)
Great walk around review. Reassuring that the brand looks to be solidly built with good parts. I am looking at Wanptek DPS3010U with updated features and wider power setting. All good and thank you for your review.
This will be good for anodizing my weaponry
Thanks Steve! I wonder why it doesn't have a ground terminal? That's where I like to hook my anti-static wristband when I wear it.
Wait your multimeter can measure noise?!! Nice! I got a fancy scope for that lol. I also wanna measure inrush current but current probes are expensive
Bought their 30V 10A one and so far very happy with it.
but this font (120V 3A(360W)) doesn't the same of 30V 10A= 300W?
I got one of the newer ones and have the voltage spike issue when turning it on from cold. The newer one has a "output" button that starts the output though, but the main switch gives a voltage spike on the + and - terminals.
I think i'll get one, they do deliver out of Poland so it should arrive in no time.
Isn't the quad opamp a TL494 PWM controller? The TNY switcher just supplies the logic&control, while the 494 is doing the heavy lifting.
I really like that you know your good Chinese brand caps from non-good ones - and don't just blanketly criticize "poor Chinese caps". Do you think the isolation from 230v to DC is sufficient?
From testing, it definitely withstands a flash test. Bear in mind, it is a low cost device though and is a little noisy on the waveform
Great video! Just ordered one, thanks!
Not a bad unit, though personally I'd be nervous about how easily it can deliver a dangerous voltage.
Eg you could accidentally flick it up to 120V just by brushing against the coarse adjustment knob.
I'd happily pay a few quid more to have some sort of lockout or maximum voltage protection.
Because it is relatively low cost, I'd be quite happy to reserve this just for higher voltage use - it's a great point though
it would be interesting to review one of their electronic DC loads (and maybe revisit this psu with it?)
Which Security Terminals do you Plan to use? Have a Link to high quality ones for me?
So does that have floating output?
Hello, witch camera you are using? I´m thinking of buy another for my youtube videos. Thank you
Nice review, and nice bit of kit. What is the minimum output voltage, does it go all the way to zero? Is the coarse voltage control a pot or an encoder? What range is there on the fine setting, or is it continually variable? Thanks!
Yes, right down to zero. They're potentiometers giving around 2V on the fine control. One upgrade could be changing the potentiometers for multi-turn types.
I just don't like the terminals of that thing, considering it can go to 120v@3A... it can be hazard if you accidentally touch bare metal. It should have fully shrouded safety terminals to lessen that chance :)
You got a new sub here.
you didn't test cc capabilities..
I want to be able to charge a 16S LiPo up to 63 Volts at 6-8 Amps Max and as low as 3 Amps when time is not of issue. Having a really hard time coming up with a power supply. Any ideas?
Hey Steve, could please you measure the voltage of the positive or negative output with respect to chassis(earth) ground? I have a similar unit and it seems to have ridiculous voltage between the two terminal output and earth ground (close to 180V!). Definitely safety hazard!
Couldnt you just short the - to ground?
great vid, thanks mate
Did you ever change those lead terminals over to safety type? I'd like to do that as well to use my same leads for my fluke meters but i can't find some terminals that i know will fit easily.
can i get 10v 30A from this power supply?, or 3A is the maximum for 10v?
3A maximum at any voltage
@@sdgelectronics tks
It might be worth checking the leads from the transistors/mosfets to the pcb after the tightening to the heatsinks looks to have twisted them?!
I did take a look, everything all looks fine 👍
I'd like to increase the brightness of the display on mine. Anyone know if it's possible?
I dont like it because of the over shoot win you start it
As for the build it the same circuit like pc power supply and i think power circuit bord its the same in other models
I have another lowish cost power supply coming, so will be interesting to see if it suffers in the same way. Thanks
Ptc for limiting inrush current??🙄🙄🙄
amazing review tks
Are these multi Turn pots? Can the fine adjust cover the entire voltage range?
No, single turn. They are non-linear adjustment though, so greater control at lower voltages.
Currently the price is almost double now
Hi, do you have an opinion about wanptek dps3010U ?
Is the output properly isolated?
I will double check with an isolation tester later
@@sdgelectronics update? Cheers
@@ReubenHorner apologies, yes it's isolated from the mains earth (and mains AC)
How many KV of isolation? Can it output be put in series (several power supplies)?
I purchased one and it was defective right out of the box.
I think the TNY chip is only providing 12v or 5v for the opamps/comparators and front panel leds ... and the 3.3v linear regulator is powering the microcontroller. The actual switcher IC may be on the other side of the board, and you have there diodes/mosfets in to-220 or similar packaged screwed directly to case - see @7:43 ... right in front of the heatsink.
One of the small transformers is used by the TNY chip, the other is most likely for feedback / current sense...
Other than this... typical Chinese stuff ... shitty electrolytic capacitors, bridge rectifier right by the primary capacitor so it can stay nice and warm and degrade over time, also outside the regular airflow so fan won't help keep that area cooler... that ntc/ptc/whatever is gonna be constantly hot as it's not shorted out using a relay or other methods...
The PI chip is driving the mosfets on the heatsink. No components on the underside. The components on the heatsink have isolating hardware on them. The airflow comes from near the front so the capacitors should get sufficient airflow - it's a relatively low power converter so heat in the power supply is minimal. It's not a premium supply by any means but not anything that could be considered bad design
i cant get over no ground
Would it be safe if I accidentally shocked myself with this at full power 120v 3 amps?
Are you still alive?
@@panashe8478 🔌⚡☠
Hi, can you adjust the intensity manually? I have the same power supply but I just can set the voltage. Could you explain me how it works more or less?
Can i anodize titanium with this ?
If memory serves, yes, I remember the voltage being something like 90 VDC for that.
Yeah, I bought this to try with my titanium anodizing, it works perfectly.
@@PkwyDrive13 thank you. This is the reason I'm looking at this. My current power supply is only 30v. How is it holding up? I saw some negative reviews on Amazon which is why I'm doing further research on this
@@bobkeller8383 I have not had any problems with mine at all, has been fine so far
@@PkwyDrive13 thank you. I just received mine today
caught my interest, until i saw the bad reviews
Hello! What were those bad reviews about? What's not good about this supply?
- Current limit protection
- Short circuit alarm stop output
- Self-recovery
BULL SHIT!!!!
All you have to do is to connect a 12V battery with reversed polarity and you can see this Power Supply die in 5 seconds!!!
(Without giving and amperage or Volt actually).
BE CAREFULL!!
sorry, did you buy this power supply ?
You might want to stick to promoting equipment with Electrical Compliance/Certification. Stay safe my man, buy professionally designed power devices only.
PS: just how did that thing made it past the UK Border Customs?? U got lucky, my guess...
Not everyone have 100s of Euro to buy a power supply ...
It did come with a booklet with the approvals listed. The sticker is actually on the bottom of this unit, but supposedly it has passed safety testing. I didn't see anything dangerous in the design - did I miss something?
Anyone know of a better unit and value for this price point?
@@sdgelectronics try to load a old 12Volt Car battery with 100mA. This device starts smoking. The Mosfet is totally burned out. Do you know which one is used on this device?
