Description
BEP Digital Voltage Sensing Relay 140 AMP 710-140A DVSR
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 second battery bank to charge. When charging stops and voltage falls, the DVSR automatically isolates the battery banks, ensuring engine start batteries are fully charged. Digital circuitry provides superior reliability and extremely low power consumption.
Features:
- 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 voltage drop compared to diode isolators.
- Ignition protected.
- Surface or panel mountable.
- Replaces previous models 113646, 113647 and 113649.
Digital enhancements:
- Multi-voltage, auto selects between 12 Volt and 24 Volt DC operation.
- Digital circuits provide very low power consumption and enhanced performance.
- Remote sensing circuitry allows optional connection from ignition switch, provides same functionality as single sense voltage sensing relay and zero power consumption when engine is off.
- Zero standby current draw when remote sensing circuit utilised with storage mode switch fitted (switch in open position).
- Remote status LED output option.
Power consumption (Standby): 1.8 mA (1.6 mA at 24 Volt DC)
Power consumption (Storage Mode): 0 mA
Cut in/cut out voltages: 13.4 Volt (26.8 Volt) / 12.8 Volt (25.6 Volt)
Warning: Ensure correct installation by a qualified marine electrician to avoid damage to battery banks or electrical system. Incorrect wiring can cause failure or unsafe operation.
Boat Hut Insight
When choosing a voltage sensing relay like the BEP 710-140A DVSR, consider not just the technical specs but also the environment it will operate in. Boats often face vibration, moisture, and temperature swings, so the relay’s robust digital circuitry and ignition protection are crucial for long-term reliability. Also, if you’re upgrading an older system, the ease of installation with this model means less downtime — a big plus when you want to get back on the water quickly. Lastly, if you’re running multiple auxiliary batteries for fridges, lights, or other toys, this relay ensures your engine start battery never gets drained, saving you from those dreaded “won’t start” mornings. A small investment in the right relay can save you hours of troubleshooting and towing fees later!
