Abstract

See full text

A recovery system for a power supply. The inventive system includes a first circuit which detects a reapplication of wall power to the power supply and generates a signal in response thereto after an interruption in the output thereof. A second circuit then automatically reactivates the power supply on receipt of the signal without operator intervention. The invention is particularly well suited for systems having multiple power supplies each operating within an associated power boundary. In this case, a first power supply provides power to a first load and a second power supply provides power to a second load. A control circuit is provided in each load. The control circuit is equipped to receive the signal indicating a reapplication of power to a power supply within another power boundary and automatically reactivate the power supply.
