Abstract

A power supply includes a component for receiving input power and a controller that measures a RMS value of the input voltage and generates a command signal proportional to the RMS value. A current regulator of the power supply receives the command signal and independently regulates current flowing through each of one or more LED strings based on said command signal. A current monitor of the power supply compares the regulated current with a predetermined threshold and transmits a power supply termination signal when an aggregation of the regulated current is less than the predetermined threshold.
