This supply is fairly stable when not connected to a driver or motor. The back EMF from my NEMA 24 did cause the voltage to fluctuate some (47.0 to 48.2 volts) But did not cause any problems with my driver or motor. My DM542T driver can accept up to 50 volts, so I would recommend 1 to 1.5 volts from max of your driver input so that back EMF will not cause you to exceed the input voltage of a driver.. I do not fault the supply for this, it is just the mature of driving a stepper motor to high rpm and slowing it back down to a stop.
This supply shows no signs of stress or heat when operating a NEMA 24 at 1350 RPMs for a continuous 25 minutes. I highly recommend this supply up to at least NEMA 24 motor sizes.
