The YIHUA PS-3010D DC Power supply – Quick Review

The glorious PS3010D with its blinking segment and cracked screen. The front panel to the screen was cracked because I flicked it with my fingernail seeing if I could shake it a bit to make the segment work. Nope, just cracked the screen.

Having needed an adjustable power supply with a bit more current, I decided to buy this guy for about $140 off Ebay. I’ve played around with it a bit and I decided to review it because I’m sure there are a lot of people like me who buy cheap test equipment. You don’t pay much and you can’t expect much, but you can just hope it does the job.

I performed a few tests that you can see below:

With the current turned all the way down, the voltage will drop to -.15 volts. This generally isn’t an issue and I’m sure that even if something were hooked up, the current would be extremely low.

Here I test the accuracy of the voltage readout. I know that .1 volts isn’t a lot but it’s be nice if you could calibrate the display like my analog power supplies.

Testing the amperage at a lower setting. Not bad at this rate.

Bringing the amperage to full. The displayed value and the measured value are quite different. This is when the LED segment started flickering. I don’t know if it’s a coincidence.

So, if you looked at the values shown, you’ll see it works OK. Anyways, here are some pros and cons to this device.

Pros:

Cheap
Reasonably effective
Knobs and switched feel good
Nice high current for a unit like this
Nice grill effect over the LED’s make it look like a dot matrix LED
Standard size case

Cons:

LOUD LOUD LOUD! Not quite vacuum cleaner loud but louder than anything else in my office.
Front power connectors are kind of flimsy and cheap
Displayed and measured values do not quite jive
Does not have a handle on the top, it’s nice to have a handle on test equipment

Otherwise, the unit works as expected and I’ll write the LED flicker off as a coincedence. It’s too bad that it’s so loud, they could’ve used a different fan or something, becomes a real distraction. If you need something like this that produces 30V at 10A, this may be good purchase.

just purchased one of these. installed it on a 12 volt fuel pump test station at work. it worked for a few days, tested around 100 fuel pumps before it malfunctioned . it got stuck on 53 volts with no current. i guess you get what 150 dollars buys you.

Good Day,
please send me a Service Manual for Power Supply WEP 3010 D on my eMail Adress

My 3010D power supply went to 53 volts and is not adjustable.
Can you send me a schematic/ service manual?

Hi Steve, I have the PS-3010D and have used it quite a bit. It seems to have a internal ground problem ISO problem. When I hook up it to my scope the current limit triggers on AC or DC coupling and when I use it in circuit I isolate the case ground works fine. I wonder if other people have had this issue. Thanks for your time, Len
