My first bench power supply. Overall happy with purchase. Read reviews to disassemble and verify connections and solder joints. Everything on my unit checked out fine, just the top carrying handle was loose. Tested accuracy and range with a decent (Extech) digital multi-meter. Full range was observed and off by 0.1A and 0.1V which were easily calibrated on the front panel. Accuracy does vary from one end of the range to the other, but within 0.1 and can be calibrated to within ~0.05 V or A within a for specific narrow range if ever required (I doubt I'd every need to). Moderate to good quality in general. Paint on the case is of poor quality (uneven, flakes easily and chipped around screw heads). Test leads are of low quality, but work fine. Excellent value and definitely suits my needs for occasional useRead full review

Sure, it's lightweight, switching power supply instead of of the "heavies" which use a heavy and stable step-down transformer. Switch supplies have got a bad name over the years, primarily because of the RF hash they are prone to produce on nearby AM/SSB receivers. But, this unit produces no HF interference. Indeed, I have several other switching supplies which do not either --- not a bit. On the other hand, I have had switching supplies that I needed to toss away, or not use anywhere my ham shack equipment. Switching supplies seem to have improved over recent years, proving that the inherent RF noise they produce can be suppressed. I do have a heavy, DC-transformer 40-amp supply, and this switching supply makes no more noise than the "big boy." There is also almost no AC riffle leak-thru; another bane of some switching supplies. This supply will give you want you want in a bench supply. For those hobbyists and folks who need a variable output power supply - and who doesn't for testing and equipment operation, this will fill the bill. Like most switchers, it's small and light, taking up little bench space, and provides the wide range of DC voltages advertised. The digital readouts are a plus, and tested against a calibrated VTVM, are accurate to within one-tenth of a volt or ampere. Of course I would always rather have a conventional DC-transformed, rectified and filtered supply, but had all switchers performed as well as this one did, I might not feel that way. :)Read full review

Works great on the audio amp project I needed it for. No problems. It's versatile and would recommend it to anyone for the price. The only con I see is that in reading the instructions, it seems to not very tolerant to abuse. Follow instructions on how to use it.

Board looks very clean with good soldering joints and wiring. Voltage output is wrong by 0.2v which is nothing really but i like it to be exact. That can be adjusted at the front thru small holes. Knobs have mold residue i needed to trim with a razor to make them turn smooth. otherwise all good. Dont know how long it will last. ONE WEEK lol

Its new, it works, the on/off switch is a little wobbly and gets caught. Overall I am happy with it. It certainly beats what I was using before,like night and day!
