Works great
I am very disappointed in this supply
GrahamH•September 6, 2015
I am very disappointed in this supply. It does basically work, once it is turned on and settles, but has a bad transient when the output is turned on. And it gets worse when you add capacitance across the output. For instance, if I turn it on, set the output to 5.0 Volts, then turn on the output, it overshoots to almost 6 Volts then settles back to 5 Volts. This is enough to trip overvoltage protection in some of my 5 Volt CPU boards. It took a lot of time to figure out that my problem was my "precision" bench supply. I called B&K Precision's service line, and they said: "It is a low cost supply, what do you expect?" I also had it go out of regulation during an AC power outage event, and it destroyed some components on the output due to much higher output than it was set for. It is a switching power supply, and puts out a lot of radio noise in the 1 to 15 MHz frequency range. I think there are better supplies for the price from other companies.
I'm very happy with this

I'm very happy with this, it's small and quiet, exactly what I needed as I don't have a lot of desk space and use it in a living room/office environment. I read some reviews elsewhere that complained bitterly about the current-limiting feature and how it's too slow, so be aware of that if you care about that aspect.
