Digital Voltage Sensing Relay (DVSR) 12/24V


Model # 14152185 | Mfg # 710-140A
Ships when available.

Enjoy the benefits of fully charged engine starting batteries and deep cycle house batteries with one easy-to-install charging system. The Voltage Sensitive Relay (VSR) allows two batteries to be charged at the same time. When the engine is started and the start battery reaches 13.7 volts, the VSR engages, allowing two battery banks (start and house) to be charged simultaneously. When the voltage drops below 12.8 volts (engine is stopped), the VSR disengages, separating the batteries.

This system eliminates the possibility of draining the start battery and protects sensitive electronics powered by the house battery from harmful engine start up spikes. Dual sensing allows the relay to sense the voltage of both batteries, activating if either is receiving a charge. Designed for systems where a battery charger or second charging source is connected to the house battery.

  • 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 three-wire connection leaves alternator wiring intact
  • No voltage 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
