Residual Voltage Immunity in Standby Mode
The power supply is immune to any residual voltage placed on its outputs (typically a leakage
voltage through the system from standby output) up to 500mV. There is neither additional heat
generated, nor stress of any internal components with this voltage applied to any individual
output, and all outputs simultaneously. It also does not trip the protection circuits during turn on.
voltage through the system from standby output) up to 500mV. There is neither additional heat
generated, nor stress of any internal components with this voltage applied to any individual
output, and all outputs simultaneously. It also does not trip the protection circuits during turn on.
The residual voltage at the power supply outputs for no-load condition does not exceed 100mV
when AC voltage is applied.

Protection Circuits
Protection circuits inside the power supply cause only the power supply’s main outputs to
shutdown. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF
for 15sec and a PSON# cycle HIGH for 1 sec will reset the power supply.
