Abstract
A power distribution module has an input line to receive power from a DC power source. A switch selectively opens the input line and blocks supply of power from the input line to an output line to be connected to a DC load. A solid state power control controls a gate drive for the switch. The solid state power control is operable to distinguish between a pre-charge mode, at which current is rushing to supply a capacitor in the downstream DC load, and a short circuit mode, at which a short circuit exists.
