PSU wiring dilemma...
(1/2) > >>
LektroiD:
Hi, I just did a continuity check on my switching PSU but the ‘COM’ which I presumed to be common ground are not connected to each other and also isolated from the chassis of the PSU, I’m wondering if I should tie all the COM connections and the chassis to mains ground (is it safe to do so)?
bob225:
standard switch mode ? all the outputs are isolated and not reference on the dc-dc transformer - don't tie it to ground, and you don't really want it referenced to earth or the mains, that sort of defeats the filtering
LektroiD:
Yes, switch mode...

So I'm guessing this is unusable for my purposes, as my power bus needs a common ground for all voltages... The +5V will not work from the COM of the +/-12V
stj:
you can tie the outputs if you need to i imagine.
nice selection of voltages, where did you get it and what's the output ratings?

It didn't explode, so all good.

One of AliExpress' finest, although I cannot find that particular one now...
Specs:
+5V 5A
+24V 1A
+/-12V 1A
