BEP Marine Digital Voltage Sensing Relay DVSR
A voltage sensing relay allows two independent battery banks to be charged from the the same charging source without complicated wiring. Boats and some caravans typically have both a start battery and service battery installed. The charging source such as an alternator is normally connected to the start battery. A voltage sensing relay is connected between the start battery and service battery. When the engine is not running the batteries are isolated avoiding discharging the start battery when using services. When the engine is started the start battery quickly recharges and then the voltage sensing relay connects the battery banks together to allow charging of the service battery. When charging stops, the batteries are isolated again. A Voltage sensing relay can also be used to supply some loads only when the battery is charging.
The BEP Marine Digital Voltage Sensing Relay (DVSR) is suitable for both 12 V and 24 V systems. Digital circuitry provides superior reliability and extremely low power consumption. The BEP Marine DVSR also features a storage / ignition circuit function which allows the DVSR to be connected to the ignition switch of an engine or remote switch. This provides optimal protection of electronics from electrical spikes and zero power consumption when ignition / switch is off.
