Excellent lab supply.
I’ve had mine for 6 months now and I love it. Don’t pay attention to the bad reviews, some people just don’t know how to read. It’s dead quiet on the outputs, the series parallel are a must for ease of amplifier testing or whatever your doing. It doesn’t overshoot, can drive large capacitances, quiet, lovely useful display. Highly recommend and am thinking about buying a second so I can have +/-66v bi-polar supply. Well worth the money. ... show more

Great price on a great power supply.
Overall you just cannot beat the price for the feature set you are getting with this unit. I am about 3 months in and have had no issues at all.

hand set voltage only
I was very disappointed in waveform generator It requires a stepped function of I think it's 10 milliseconds per step which means it cannot effectively create any sine wave over about .01 hertz And stepped functions have to have a big jump or rapid change for them to be meaningful. So even though it is labeled as power supply dynamic voltage It is really only good setting it to a voltage and using it at that fixed voltage. ... show more
