Would be nice to see the common mode noise on the outputs. I got a 60V single output switcher from uni-t a month back, and the flyback topology on that one unfortunately couples so much common mode noise into the output that you can't really use it with an oscilloscope. Just putting a grounded probe onto the negative lead noises up your scope display with +-0.5 V wideband noise, unless you remove the pigtail and ground the probe directly to the slip ring. Which is just not practical. Sadly most power supply manufacturers don't even specify the common mode noise.

Hi James. Which model did you purchase? Did you get it from an overseas seller?

[@KissAnalog]

This sounds like a great test! I'll do this very soon;)

[@KissAnalog]

Uni-T has great customer response as well:)

I like the led's above the jacks. A nice "at a glance" feature. I wish vendors were more consistent with their product line colours. I know, I know, it doesn't affect the functionality.

[@KissAnalog]

Thanks - I like those LEDs too. Makes it fast to see that you actually engaged the switch;) I do like consistency too - but I gotta say I like the Black;)

Noob's question: An amplifier board needs +/- VDC. How does a bench PSU do this? Does it have + and - leads so one just needs to adjust the necessary power to the board? Thanks.

[@KissAnalog]

Great question! A power supply like this Uni-T with 2 or more outputs can do this. Each output is isolated from the other, so you stack them like 2 batteries so where the plus of one connects to the negative of the second - this is the middle point of the Plus and Minus outputs. Does that make sense?
