The Digital Voltage Sensing Relay (DVSR) provides a highly efficient but inexpensive solution for automatic charging of a second battery bank. It ensures correct charging while removing the risk of flat start batteries. When the voltage on the first bank rises sufficiently, the DVSR engages allowing the second battery bank to charge. When charging stops and 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…)
Charges engine starting batteries before combining auxiliary bank for charging
Protects start batteries from becoming flattened by domestic loads
Isolates electronics from harmful electrical surges from starter motors
Simple to install 3-wire connection, leaves alternator wiring intact
No volt drop vs. diode isolators
Ignition protected
Surface or panel mountable
Digital Technology Provides:
Multi voltage, auto selects between 12V and 24V DC operation
Digital circuits provide very low power consumption (<2mA in standby, up to 8xmore efficient than analog models) and enhanced performance
Remote sensing circuitry allows optional connection from ignition switch, providessame functionality as single sense VSR and zero power consumption when engine is off Zero stand by current draw when remote sensing circuit utilized with storage mode switch fitted (switch in open position)
