Blue Sea Systems ML-Series Automatic Charging Relays – 24V – 7621100-BSS

Blue Sea Systems ML-Series Automatic Charging Relays – 24V – 7621100-BSS

Enhance Battery Management with Blue Sea Systems Automatic Charging Relays # 762110-BS   24 VOLT

The Blue Sea Systems ML-Series Automatic Charging Relays are high-capacity 500A magnetic latching (bi-stable) relays designed for advanced battery management. These relays automatically combine batteries during charging and isolate them during discharging and engine starting, optimizing battery performance and ensuring protection for sensitive electronics. The magnetic latching (ML) design draws minimal current in the ON state, enhancing energy efficiency.

The relays offer configurable Start Isolation (SI) to temporarily isolate house loads from the engine circuit during cranking, protecting delicate electronics from voltage sags. Additionally, the Engine Isolation (EI) function can be configured to isolate two engines while both are running, safeguarding engine electronics and maximizing alternator output. For added safety and control, the manual override knob allows for operation with or without power and includes a LOCKED OFF setting for secure servicing.

These relays sense charging on two battery banks and provide an LED output for remote indication of switch state, compatible with optional LED or Remote Control Contura Switch with integrated LED. The 3/8″-16 tin-plated copper studs ensure maximum conductivity and corrosion resistance, while the 7/8″ stud length accommodates multiple cable terminals. Durable one-piece stainless steel flange nuts guarantee secure connections, and silver alloy contacts ensure high reliability for live switching.

    Blue Sea Systems 12V Automatic Timer Disconnect 7615-BSS

    Optimize Battery Systems with Blue Sea Systems 12V Automatic Timer Disconnect  7615-BSS

    The Blue Sea Systems 12V Automatic Timer Disconnect offers four powerful functions to manage battery systems effectively: Timer Disconnect, Low Voltage Disconnect, Automatic Charging Relay, and Solenoid. These features are designed to optimize battery performance and protect power systems from unnecessary drain.

    The Timer Disconnect function triggers the relay to connect battery power to devices, and once the signal is removed, the timer starts, disconnecting devices after a preset time ranging from 15 minutes to 4 hours. The optional charge sense feature can be used instead of a 12V signal to simplify wiring. The Low Voltage Disconnect feature automatically disconnects devices when battery voltage drops below a set threshold (11V, 11.5V, or 12V), preserving battery life and preventing over-discharge. It can work alongside the Timer Disconnect for even better power management.

    The Automatic Charging Relay combines two battery banks for charging from a single source, automatically isolating them when charging stops or during discharge. This function is particularly useful for auxiliary batteries that are AGM or larger than the starting battery. Lastly, the Solenoid provides instant connection or disconnection of the relay with a 12V signal, without any time delay, allowing for manual control of battery connections.
