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:

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.

  1. 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.

  2. Good Day,

  3. 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
