Marine Electrical BEP 12/24V 140A Digital Voltage Sensitive Relay

The Digital Voltage Sensing Relay (DVSR) allows the charging of a second battery bank from any single charging source. When the voltage on the charged bank rises sufficiently, the DVSR engages allowing the 2nd battery bank to charge. When charging stops and the voltage falls, the DVSR automatically isolates the battery banks, ensuring that engine start batteries are kept fully charged. Digital circuitry provides superior reliability and extremely low power consumption.Safely charge two or more independent battery banks from one charge source (alternator, battery charger).It charges the engine starting batteries before combining the auxiliary bank for charging.
