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.

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

My power supply is varying the voltage alone .
Can you send me a schematic/ service manual?
Thank You, Jim

Looking for the wiring diagram for a 3010KDS power supply
that I am trying to fix.
Regards Roger.
