A method for derating a power source to limit damage to a drive train of a machine including determining a first operational parameter associated with a power conversion unit and a second operational parameter associated with the power source, selecting, based on the first operational parameter associated with the power conversion unit and the second operational parameter associated with the power source, a power source derate value, and reducing an available power output associated with the power source according to the derate value.

Method for derating a power source to limit damage

A machine includes a plurality of electronic controllers electrically connected to an electrical power source along a first electrical circuit through a first relay and along a second electrical circuit through a second relay. A relay controller is directly connected to the electrical power source along a third electrical circuit, and is in communication with the first relay and the second relay. The relay controller is configured to open or close the first relay or the second relay in response to a power requirement indication.
