BEP Marine Digital Voltage Sensitive Relay 140A 12/24V – BEP-710-140A
Manage your vessel’s dual-battery system intelligently with this digital voltage sensitive relay (VSR) from BEP Marine. The BEP-710-140A automatically connects your battery banks when the charging voltage rises above a set threshold — allowing both banks to charge simultaneously from your engine alternator or solar input — then disconnects them when voltage drops, ensuring your start battery is always protected and ready.
Rated at 140A continuous and compatible with both 12V and 24V systems, this VSR is built for the demands of larger recreational and commercial vessels where reliable battery management is critical. The digital design provides precise voltage sensing and switching, reducing the risk of false triggers that can occur with older analogue relay designs.
Key Features
- 140A continuous rating — suitable for larger vessel electrical systems
- Compatible with 12V and 24V battery systems
- Digital voltage sensing for precise, reliable switching
- Automatically combines banks during charging, isolates during discharge
- Protects start battery from being drained by house loads
- Manufacturer Part Number: BEP-710-140A
Parts Desk Insights
Best Use Case: The BEP-710-140A is the right choice for vessels running a dedicated start battery alongside a house bank — particularly those with higher electrical loads such as inverters, refrigeration, or multiple electronics. The 140A rating handles the output of most marine alternators without restriction, making it well-suited for twin-engine setups or vessels with high-output charging systems. If your system uses a battery isolator instead of a combiner relay, consider the ProMariner Battery Isolator as an alternative approach to dual-bank management.
