Hi everyone,
I've decided to replace the power supply on my delta 20 control. I've ordered a meanwell qp-320f, and it should be arriving tomorrow.

Can anyone provide guidance on the process? In particular, I'm not sure where to put the white lead labeled "P.F." on the new PSU. On the old PSU, it connects to the centre of the circuit board via a molex connector.

I think the rest of the connections should be easier to figure out, but if anyone has a handy list of what goes where, that would also save a bunch of time.

Thanks in advance,

Lee
