Average Reviews:
(More customer reviews)The two most important things about this power supply are:
(1)The single adjustment knobs - 1 for voltage, 1 for amperage - are sufficient for both fine and coarse adjustments.With a little patience its easy to adjust by 1/100th.1/10th or greater adjustments are mostly effortless.
(2)The output reading on the display is correct.I spent about 20 minutes when this first arrived comparing voltage and amperage output with a multimeter for the entire range that this power supply supports.All values were within 0.01 of the reading on the display (*note: I was hoping for 0.5 or better, so the accuracy that I found was a pleasant surprise).
