Newmar ERC-12-35 Emergency Relay

The Newmar Power ERC-12-35 Emergency Relay is an emergency relay and charger for keeping communications equipment supplied with backup DC power when AC power to the power supply is lost or the supply fails. When DC voltage is lost, the unit switches equipment input to a standby battery, then returns the equipment to the power supply when service is restored.
