Automotive Relay

On Board Marine Group Limited

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 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. Digital enhancements have introduced remote sensing circuitry that allows an optional connection from the ignition switch to provide the same functionality as single sense VSR and zero power consumption when engine is off. Another benefit is a zero stand by current draw when remote sensing circuit is utilized with a storage mode switch fitted (switch in open position). 	 Safely charge two or more independent battery banks from one charge source such as an alternator or 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 	 Replaces previous models 710-125A and 710-125A-DS 	 Multi voltage, auto selects between 12 and 24V DC operation 	 Digital circuits provide very low power consumption and enhanced performance 	 Remote status LED output option 	 Continuous rating: 140 	 Engages: 13.2 VDC, Disengages: 12.7 VDC
