[sdiy] Power-one supply setup question

[Paul Schreiber]

S terminals are "Remote Load Sensing" and some Power Ones have them 
internally connected, but most do not. So they have to connect to the 
respective output (-S to -OUT) and you can either:

a) short across right there on the supply, which is easy but defeats the 
purpose
b) run the extra wire(s) from the terminal to the load connection point.

The purpose is to remove the IR drop in the leads from the supply to the 
load. IN a synth drawing 1A or so....pfffttttt!!! Use 18ga or 16ga wire and 
you won't care about the 1mv of drop :)
