Blue Sea Battery Voltage Sensing Relay (MPN: 7623-BSS)

Efficiently manages dual battery systems for optimal performance.

The Blue Sea Battery Voltage Sensing Relay is designed to manage the charging and discharging of two large battery banks effectively. Operating at 24 volts DC, this relay supports a continuous rating of 500 amps and an intermittent rating of 700 amps, making it suitable for high-output alternators. The magnetic latching feature ensures low current draw in both the ON and OFF states, while allowing for quick transitions when changing states.

This relay offers dual sensing capabilities, monitoring the charge on both battery banks to ensure efficient operation. It can be configured for start isolation, protecting sensitive electronics during engine cranking, and engine isolation, which maximizes alternator output while safeguarding engine electronics. The LED output provides clear remote indication of the relay's status, including when batteries are combined or isolated.

Constructed with tin-plated copper studs for enhanced conductivity and corrosion resistance, the relay also features silver alloy contacts for reliable switching of live loads. This combination of features makes the Blue Sea Battery Voltage Sensing Relay a robust solution for managing complex battery systems.
