PSU - getting +12, -12 and 0 volts
« on: February 22, 2019, 07:33:12 am »
I just purchased a Siglent SPD3303X-E bench power supply. It has three outputs, one of them being a range of fixed voltages, the other two being fully adjustable.

What I need is to be able to get +12, -12 and 0 volts from the unit. Would I do this by setting the outputs to independent mode, set both to 12 volts, then combining the inner + and - terminals to get my zero volt, using the remaining terminals for the + and - voltages?

Going by the datasheet it supports independent, series and parallel modes.
Series mode is what you're looking for.

So serial mode and combine the remaining terminals as the zero reference?

let me add to this question: what would it happen if I were to short the + of one channel to the - of another channel (both active) in idependent mode?

Cheers

I figured it out. Set to serial mode. The remaining terminals are zero volt. You can test by checking the voltage, should be 1/2 the output between the outer + or - terminals and any of the center ones.
