The Blue Sea Systems 7622 ML-Series Heavy Duty Automatic Charging Relay is designed for robust and reliable power management in marine, RV, and industrial applications. Featuring a manual control switch, this relay allows for added safety and flexibility, enabling control with or without power and providing a 'Locked Off' option for maintenance and servicing. The relay includes the ML-Series Remote Control Contura Switch PN 2146, ensuring easy operation from a convenient location. With a continuous current rating of 500 amps, it is suitable for high-output alternators and demanding electrical systems. The magnetic latch (ML) technology ensures low power consumption, drawing less than 10 mA during the 'ON' or 'OFF' states, and only moderate current during state changes, contributing to energy efficiency and system stability. The relay can be configured for start isolation, protecting sensitive electronics during engine cranking, and engine isolation, which prevents electrical interference when multiple engines are running. It also detects charging across two battery banks, making it ideal for complex power setups. The relay supports high-output alternators up to 500 amps and features LED indicators to remotely display battery status, including whether batteries are combined, isolated, in voltage lockout, or engine start and run states. The device is built with 3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance, with a stud length of 7/8" (22mm) that accommodates multiple cable terminals. Additional features include label recesses for circuit protection and silver alloy contacts ensuring high reliability during switching of live loads. This relay is an essential component for maintaining electrical system safety, efficiency, and protection in demanding environments. Please consult the owner's manual for detailed installation instructions, available online. Note that this product may contain chemicals known to cause reproductive harm, as detailed in the California Proposition 65 warning.
