of a DC short circuit or current overload, the station’s electronic overload protection
circuit will shut down the DC output to avoid damage. As soon as the fault condi-
tion is removed, the auto-reset circuitry will automatically restore system power –
even under full load conditions. There is no need to disconnect stations
to allow the power supply to reset.
