Blue Sea Systems 12V Automatic Timer Disconnect

Blue Sea Systems 12V Automatic Timer Disconnect: Versatile Battery Management for Optimized Power Control

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.
