Power control device for redundant reset outputs in an atm system

摘要

A power control device includes a power control circuit connected to a power supply and a supervisory power monitor unit for outputting a control pulse to the power control circuit for approximately one second. The power control circuit switches the power supplied at the power control circuit input to an output of the power control circuit when the control pulse is deasserted. A reset output logic device receives the power supplied from the output of the power control circuit when the control pulse is deasserted and outputs the power to reset outputs in a distributed power system.
