Hey guys,
As part of the checks during the build of my CNC control box, I thought I should confirm the voltage of my 48v power supply. It is an S-350-48v with 7.3A output. When I first measured, it was in the 50's, something like 52.5v, so I adjusted the pot to read 48.5v (close as I could get it as I mounted it in a real inconvienient location). My question is, did I do the right thing in adjusting it closer to spec or do they normally ship high to account for voltage drop under load? I haven't got to the point of sending power to the drivers, so no harm done, but if you guys normally run your power supplies a little hot, please chime in and let me know why and any other tips on setting the voltage. The drivers are Wantai DQ542MA, breakout board is a generic DB25-1205, steppers are 57BYGH633.
Thanks...
