Protection functions
output overvoltage protection (30Vdc typ. / 32Vdc max.)
active (input inrush current limiter)
Overload / short-circuit current -- min. 40A (max. 44A) load impedance Series / parallel operation -- Power supplies can be paralleled to increase the output power. The output voltage of all power supplies shall be adjusted to the same value (+/-100mV) in Single use mode with the same load conditions on all units
Back-feeding loads max. 35V -- The unit is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is ON or OFF. The absorbing energy can be calculated according to the built-in large sized output capacitor.
