Abstract
An overvoltage protection device includes a disconnect circuit configured to be coupled to a voltage source having a phase conductor and a neutral conductor, an output voltage connection coupled to the disconnect circuit; and a microprocessor circuit in communication with the disconnect circuit. The disconnect circuit is also configured to detect an overvoltage condition with respect to the phase conductor and the neutral conductor and to provide a first signal to the microprocessor circuit indicating whether the overvoltage condition is detected. The disconnect circuit is further configured to disconnect the phase conductor and the neutral conductor from the output voltage connection in response to a second signal from the microprocessor circuit if the overvoltage condition is detected, and to connect the phase conductor and the neutral conductor to the output voltage connection in response to the second signal if the overvoltage condition is not detected.
