Bluewater Auto Charging Relay 12V, 140 Amp - Battery Management System for Marine and RV Applications - 9800-7101-00

Bluewater Auto Charging Relay 12V, 140 Amp - Battery Management System for Marine and RV Applications

The Bluewater Auto Charging Relay (ACR) Part Number 9800-7101-00 is a high-performance device designed to optimize battery charging and protection in various vehicular and marine environments. With a continuous rating of 120 amps and an intermittent capacity of 140 amps, this relay is suitable for managing dual battery systems, including starting and house batteries, as well as navigation and lighting batteries on sailboats and fishing boats. Its robust construction ensures reliable operation in harsh conditions, featuring an IP67 waterproof rating and ignition protection for marine and RV applications. The relay automatically manages battery connections during charging cycles, connecting batteries when voltage levels are appropriate and isolating them when voltage drops to prevent deep discharges. It also incorporates Start Isolation (SI) to safeguard sensitive electronics from engine cranking surges by temporarily disconnecting house loads, indicated by a slow-flashing yellow LED. Dual-color LEDs provide real-time status updates, including fault, charging, discharging, combine, SI, and override modes, facilitating easy monitoring and troubleshooting. The relay supports high-output alternators up to 120A, making it suitable for demanding power systems. Key features include an under-voltage lockout that prevents relay engagement when battery voltage falls below 9.5V for 12V systems, or 19V for 24V systems, ensuring safe operation. The durable design and support for cables up to 4/0 AWG make this relay ideal for marine, RV, and utility applications where reliable battery management is critical. Installation is straightforward, and its compact, waterproof design ensures longevity and dependable performance in challenging environments, making the Bluewater Auto Charging Relay an essential component for efficient and safe battery system management.
