Zusammenfassung:A direct current (DC) overvoltage monitoring and protection device includes an overvoltage sensor operably connected to an electrical power input line. The overvoltage sensor is configured to change state upon detection of a voltage over a preselected threshold. An overvoltage relay is operably connected to the overvoltage sensor. The overvoltage relay includes one or more relay switches configured to move between a first position and a second position when the voltage over the preselected threshold is detected. An independent relay power source is operably connected to the overvoltage relay to provide electrical power to the overvoltage relay, separate from the electrical power being monitored via the electrical power input line.
