Notes: (1) Maximum o/p power: 90-120W for convection cooling, 150-310W for 400 or 600LFM Forced air cooling.
(2) Maximum load is the continuous operating load of each rail. But the maximum load of each rail can't be drawn from all outputs at the same time.
(3) Total combined current of V1 & V2 should be 50A.
(4) Minimum load is only required when PSUs do run in parallel.
