Abstract
A power supply monitoring apparatus, for which a plurality of different preset reference current values and corresponding permitted times are provided, includes: a cutoff device; current detection circuits; overcurrent detection circuits; an idle-up command circuit; and a low voltage detection circuit. When an overcurrent detection circuit detects a current value equaling or exceeding at least one of the preset reference current values, and when that condition continues for a time equaling or exceeding a permitted time corresponding to the pertinent reference current value, the circuit transmits a command to the cutoff device to interrupt the current supplied to a power feeding path. Further, when the idle-up command circuit detects an increase in a supplied current, an idle-up command is issued.
