I bought this power supply along with a set of power jacks for testing electronics like toys, radios, routers, and possibly the odd laptop. Its rated output is ample for this purpose and the controls are intuitive and precise. The indicated voltage and current seem to be within the margin of error of my cheapo multimeter. It runs cool due to the fan which varies based on the load. When running, the fan is relatively quiet and has a hushed sound due to being muffled inside the unit. It's light (about 4 lbs), but feels well-built due to the metal case and sturdy knobs. I tested it on a few electronics I had laying around and they all worked fine, as expected. Overall, I'm very satisfied with this unit.

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

This instrument is pretty versatile. My specific need is to power a small microscope lamp. It is imperative for me to not exceed 2.5 amps which would blow out the bulb. This device allows effective control. This device is compact and easy to use.

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
