Abstract
A plug-in power supply includes a housing dimensioned to fit into a space designed to accept a circuit breaker in a load center to provide D.C. power from an A.C. main power. The housing encloses a circuit card that has components that are connected between A.C. inlet terminals and D.C. output terminals to provide a peak current for a short duration, limit the output to a D.C. voltage maximum, and interrupt the output current when the output voltage drops below a certain level.
