Abstract
An overvoltage protection unit includes a power circuit module and a controller module. The power circuit module receives power from a power source on an AC input and includes a rectifier that converts voltage on the AC input into a DC Link output voltage, and an AC input current sensor that senses a current on the AC input. The controller module provides an output to terminate power from the power source based upon the DC Link output voltage and a sensed current from the AC input current sensor.
