Intelligent Battery Management for Marine Applications

The BEP Marine 710-140A Voltage Sensing Relay (VSR) is an advanced solution for efficiently managing battery charging in marine environments. Designed to safely charge multiple independent battery banks from a single source, this device ensures that your engine start battery remains fully charged while seamlessly managing auxiliary battery power. With digital circuitry for enhanced reliability and extremely low power consumption, this VSR is an essential component for any marine electrical system.

Advanced Digital Voltage Sensing Technology

The BEP Marine 710-140A DVSR automatically engages when the voltage of a charged battery bank reaches the necessary level, allowing a second battery bank to charge. Once charging stops and voltage drops, the relay isolates the battery banks to prevent depletion of the starting battery. The integration of digital enhancements, including remote sensing circuitry, allows for added control with zero power draw when the engine is off.
