Blue Sea Systems 7615-BSS Automatic Timer Disconnect for 12V DC Systems

The Blue Sea Systems 7615-BSS Automatic Timer Disconnect is an essential device for managing your battery power efficiently in 12V DC systems. Designed for marine and RV applications, this relay-based controller automatically disconnects devices after a preset time, helping to preserve battery life and prevent over-discharge. The timer feature allows you to set disconnect durations ranging from 15 minutes up to 4 hours, providing flexible control tailored to your needs. The relay is triggered by a 12V signal, activating the connection to your devices, and automatically disconnecting them when the timer expires. Additionally, the device incorporates a low voltage disconnect function, which senses battery voltage levels and disconnects devices if the voltage drops below set thresholds, further protecting your battery from damage due to deep discharge. This feature can be used in conjunction with the timer to optimize power management, ensuring devices are disconnected before the battery reaches critical levels. The unit's robust construction includes tinned copper terminal studs rated for continuous currents up to 120A, with intermittent ratings up to 210A for short durations. The device is compatible with cable sizes up to 1/0 AWG, making it suitable for high-current applications. Its input voltage range spans from 9.5V to 16V, accommodating typical vehicle and marine power systems, while the over-voltage lockout at 16V prevents damage during voltage spikes. The timer disconnect's compact design is lightweight yet durable, with terminal stud sizes of 3/8-16 (M10) and a terminal ring diameter clearance of 1.12 inches. This device is engineered with a tinned copper stud material for enhanced corrosion resistance and long-term durability. Overall, the Blue Sea Systems 7615-BSS Automatic Timer Disconnect offers reliable, automated power control, making it an ideal solution for safe and efficient battery management in various 12V systems.
