Good little power supply. Can't beat the price.
1 of 1 found this helpful Needed some simple lab/bench power supplies and saw these at a very low price, so I bought 4 of them. All 4 worked as advertised, right out of the box. Digital voltage display is easy to read and accurate enough for general power supply use (all 4 read with +/-0.1V of actual voltage, when checked against a precision reference). There's a switch that allows the digital display to read an external voltage, rather than the power supply output; a handy feature. Analog amp-meters on all 4 supplies worked and appeared to be reasonably accurate, although I did not check these against a reference. Have only had the supplies for a few days, so time will tell regarding reliability. I did a 2 hour "burn-in" of the 4 supplies, at 10V and about 250 mA, and all at least made it through this infant mortality period. The TO-3 transistor on the back gets pretty warm under load, so I would hesitate to run these for long periods of time near their rated load of 1 Amp. Outputs are floating unless you ground them, so you can easily series 2 for a bipolar +/- 15V supply, or series 4 for a +/-30V supply. The instruction booklet was barely legible and somewhat humorous (obviously translated into English by someone with little knowledge of the language), but this is unimportant for such a simple device. The power supplies were apparently originally designed for mobile phone diagnosis, and come with some interesting (and perhaps useful to some) leads with multiple alligator and pin clips. There's a radio-frequency power LED bar graph on one side of the digital display, with limited information in the instructions, but this is not a feature I will want to use anyway. Overall, appears to be a nice little supply at a great price.
