Abstract
A power supply including an input configured to receive input power, an output configured to provide output power to a load, at least one relay, a crowbar circuit configured to selectively divert the input power away from the load, and a controller configured to detect a high-voltage condition at the input, activate, in response to detecting the high-voltage condition at the input, the crowbar circuit to divert the input power away from the load, output, in response to detecting the high-voltage condition at the input, a signal to operate the at least one relay to transition from a first state to a second state, and deactivate the crowbar circuit in response to a determination that the at least one relay has transitioned to the second state.
