KiprimProgrammable DC Power Supply (0-60 V 0-5 A) 110V Input High Precision 4-Digit Multiple Protection with PC Software and USB Charging

Bought the 30V. On screen voltage and current readings are surprisingly close to my calibrated meter. Nice to have the voltage/current graphed on screen --scales nice. Controls are simple and fairly polished--not awkward like other brands in this price range. Wish it was a little brighter and better viewing angles.. Decent size --fits on test bench with small footprint. Good value for the money.

SOFTWARE DOWNLOAD LINK IS AT THE BEGINNING OF THE PRODUCT DESCRIPTION!! Note: this is not needed unless you want to control it from a PC.NOTE: The .rar file at that link has a long filename, as do the nested directories, which causes Windows problems (failed my first try due to these long filename paths). Windows error messages (or lack thereof) are useless (Windows fault!).SOLUTION: Unzip (7zip) the contents to your root drive, and/or drag out the folder "iPowerCtrlv___" to a higher level directory, or even your C: drive, and install from there. Then it worked a treat. Also had to reboot to recognize the device.Small and extremely functional, doesn't take over my workbench. Love the display: your choice of history graph (good for tracking charging), or large output V&A display. All needed values shown on display at all times: Set values (V & A), Present output (V & A), Limits (OVP & OCP), Watts, Mode (CV vs CC), Time, On/Off - all except total Ah. Output within 0.01V of my voltmeter.Buttons & knob are simple, but everything you need. 4 memory slots (knob to select).Software spartan, but functional - 10 hotkeys for V/A settings, 100 memories, output control, configurable graphs (with export).The ONLY thing missing on this is total Ah, and I wish the fan was a little quieter - it runs even if the output is off (no load). Oh - and would be nice if the power switch was in front for ease of access on a workbench.Kiprim also responded within 24 hours to my request for the download link - and NOW I notice it was already at the top of the Product Description <insert sheepish grin>.If you want a 30v/10A supply with more than just V/A/W displayed, this is the one to get - or spend a lot more.Will update if there's any change ...

I bought two of these. One is the 30V 10A model which works great after adding a thermal switch to quiet the loud fan down when the supply is under light loads.This review is about the 60V 5A model which is functional but not at all accurate. Strangely the fan on this model is quiet from the factory and only ramps up when the power supply gets warmer. The fan speed does vary a good deal over the course of 30 seconds or so which makes the supply a little annoying if you happen to be working near it. I think for the low price I can tolerate the fan behaviour.Please see the attached pic for the issue with the current reading on this supply. The new supply is on the right and disagrees with both the other power supply (in the middle) and with the DMM on the left as to how much current is flowing. All three devices are connected in series so their currents are identical.I think I might send this one back and hope for a better one.Edit: I contacted the seller who offered to replace this defective unit at no cost. The replacement just arrived today and is bang on accurate just like the first power supply I bought from them. Seems the defective unit was just a fluke. I'm changing my review to 5 stars due to the excellent customer service I received and the fact that the new power supply works as expected.

It does a good job for what it is.It is not truely accurate. Mine is off by 0.4V. If its going to have the "ability" to do tenths of Vs, it needs to be accurate.The graphing is a nice touch.If youre just using it to charge batteries, or run Christmas lights, etc. Its a good unit.If you need a very accurate power supply, this isnt it.Its cheap, and does what you expect a cheap unit to do, so it is worth the price point.

Works great! The scope function turns out to be wonderful.

Very good quality. Display is very nice. I have been in the car business for 40+ years and have just been using a name brand 12 v power supply to bench test parts. This thing is over the top. It will display how many amps the load is using. This will help diagnose a part that has higher than normal internal resistance that may be missed during normal testing.

It only lasted 3 maybe 4 months before short circuit and warranty said a year but manufacturer is being hard to deal with it blows fuse as so it powered on no display they want me to buy more fuses and continue to try again to get it replaced
