The Blue Sea Systems ML-ACR Automatic Charging Relay with Manual Control (Model: 7623-BSS) is a must - have for efficient battery management. It automatically handles the charging of two large battery banks and enables paralleling for emergency starts. With a 500 - Ampere continuous rating, it's perfect for high - output alternators. The Magnetic Latch design draws very low current. It features dual sensing to monitor charge on both battery banks. The Start Isolation (SI) can safeguard sensitive electronics during engine cranking, and Engine Isolation (EI) protects engine electronics and maximizes alternator output. The manual control switch adds an extra safety layer, allowing control with or without power and offering LOCK OFF for servicing. This 500 Amp magnetic latching relay combines batteries during charging and isolates them when discharging or starting the engine. Specifications include a 24V DC nominal voltage, 13mA operating current, and more. In the box, you'll get the ML - ACR relay and an SPDT Remote Control Contura Switch.
Using the Blue Sea ML - ACR Automatic Charging Relay is straightforward. First, make sure to connect it according to the specified cable sizes and terminal stud torques. During normal use, the relay will automatically manage the charging of your two battery banks. For emergency starts, you can parallel the battery banks. If you need to perform maintenance or want extra control, use the manual control switch. You can turn it on or off with or without power and use the LOCK OFF function for servicing. When starting the engine, the Start Isolation feature will protect sensitive electronics, and when both engines are running, the Engine Isolation will keep the engine electronics safe. Always operate the relay within the specified temperature range of - 10°C to 60°C. Check the cable connections regularly to ensure they are tight and in good condition. Also, be aware of the amperage ratings to avoid overloading the relay. With proper use and maintenance, this relay will serve you well for a long time.
