BEP Digital Voltage Sensing Relay DVSR - 12/24V

The Digital Voltage Sensing Relay (DVSR) is an essential component for marine and boating electrical systems, enabling efficient and safe charging of multiple battery banks from a single power source. Whether you're powering your boat's engine start batteries or auxiliary systems, the DVSR ensures optimal battery performance and longevity by intelligently managing the charging process.

Key Benefits

• Dual Battery Management: Seamlessly charge two or more independent battery banks from a single alternator or battery charger.
• Engine Battery Protection: Prioritizes charging of engine start batteries before activating the auxiliary bank, preventing engine battery depletion by domestic loads.
• Enhanced Safety: Isolates electronics from harmful electrical surges generated by starter motors, safeguarding sensitive marine electronics.
• Reliable Performance: Digital circuitry ensures superior reliability and extremely low power consumption, ideal for marine environments.
• Easy Installation: Simple 3-wire connection maintains the integrity of existing alternator wiring, making installation straightforward.
• Versatile Mounting: Can be surface mounted or panel mounted to fit various marine vessel configurations.
• Automatic Voltage Selection: Supports both 12V and 24V DC systems, automatically selecting the appropriate voltage for your setup.
• Remote Monitoring: Optional remote status LED output allows for easy monitoring of the relay's status from a convenient location on your vessel.
• Zero Standby Power: When using the remote sensing circuitry with a storage mode switch, the DVSR draws no standby current, conserving battery life when the engine is off.
