DVSR: Dual Battery Charging Made Easy
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
12 and 24V DC operation
• Digital circuits provide very low power
consumption (<2mA in standby, up to 8x
more efficient than analogue models) and
enhanced performance
• Remote sensing circuitry allows optional
connection from ignition switch, provides
same 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)
• Remote status LED output option
