[sdiy] My PSU...

[Tim Ressel]

Drew,

Never fear, it will all become clear. All those
S-things are for remote sensing. This is used to
compensate for voltage drops along the wires. The many
connections is because your power supply can sense
drops on the ground wire as well.

I have a Power-One that has the exact same setup. I
use the +OUT, COM, and -OUT, and ignore the sense
posts. Yours may need the posts jumpered, but I'm
guessing it would have come jumpered from the factory
if it needed jumpers. So just plug it in and see if
you get your voltages.
