I have my 1st proper bench PSU. It's a Siglent SPD3303X-E, seems quite nice so far. It's all linear, not SMPS. It has 3 independent outputs, each with it's own +/- terminal, and that's all isolated from chassis GND (at least when it's turned off anyways, I didn't want to check contin. when powered). And there's also a chassis GND terminal, connected to mains Earth-GND. CH1/2 can operate in series or parallel mode.
Does it have to be used anytime I want to connect the (-) terminals together , in independent mode. And then would I just connect the (-)'s to (GND) ? The instructional manual doesn't seem to say, they just label it, I don't see it mentioned after that.
Also in series mode, you use CH1(-) and CH2(+) for up to 64V. What if in independent mode, you want to stack the channels like any other 2 voltage sources ? I never used multi-rail bench PSU before.
