For what it's worth, those using 2 or more supplies connected together
to get more amps, here's a suggestion.
For those with remote voltage sense lines, these lines should be
connected as close to the load (amp) as possible. This allows the power
supply to overcome the IR loss in the cable between the supply and the
amp. All connectors used should be crimped and soldered. Remember,
you're strivng for all the "E" at the amp and therefore you can discount
the loss in the cables.
If the sense is connected to the + & - at the supply then the IR drop in
the cable will not be compensated for. A .2 volt drop in DC cables is
equal to ~1.4% voltage drop, no load to load. Most supplies should be
able to provide +/- 0.05% or better.
Happy New Year
