BEP Marine 710-140A Digital Voltage Sensing Relay DVSR 12/24V

The BEP Marine 710-140A Digital Voltage Sensing Relay (DVSR) is an intelligent battery management solution designed to charge multiple battery banks from a single charging source while maintaining complete isolation when not charging. This dual-voltage unit automatically detects and operates on either 12V or 24V DC systems, making it ideal for marine, RV, and commercial vehicle applications.

How It Works:

When the DVSR detects sufficient voltage rise on the primary battery bank, it automatically engages to allow the secondary battery bank to charge. Once charging stops and voltage drops, the relay immediately isolates the battery banks, ensuring your engine start batteries remain fully charged and ready. The advanced digital circuitry provides superior reliability with extremely low power consumption compared to traditional electromechanical relays.

Key Features:

• Automatic 12V/24V DC voltage detection and operation
• Charges engine starting batteries first before combining auxiliary bank
• Protects start batteries from discharge by house loads
• Isolates sensitive electronics from electrical surges generated by starter motors
• Simple 3-wire installation leaves alternator wiring intact
• No voltage drop unlike diode-based isolators
• Digital circuitry ensures very low power consumption and enhanced performance
• Optional remote sensing circuit connection from ignition switch for zero power draw when engine is off
• Remote status LED output option for monitoring relay status
• Ignition protected design for safe marine environment operation
• Versatile mounting options: surface or panel mountable
• Replaces previous BEP models 710-125A and 710-125A-DS

Applications:

Works with any single charging source including alternators, battery chargers, and solar charging systems. Perfect for vessels with separate house and engine battery banks, or any application requiring automatic battery bank isolation and charging management.

Installation:

The straightforward 3-wire connection integrates seamlessly with existing charging systems without modifying alternator wiring. Optional remote sensing wire can be connected to ignition switch for enhanced functionality and zero standby power consumption.
