ML-ACR Automatic Charging Relay with Manual Control - 12vDC 500A

The ML-ACR Automatic Charging Relay is engineered for serious marine power systems. This 12VDC, 500-amp relay automatically manages charging between two large battery banks, connecting them when your alternator is running and isolating them when the engine shuts down. Need emergency starting power? Simply parallel both banks for maximum cranking amperage. The Magnetic Latch design is exceptionally efficient, drawing less than 40mA in standby mode to monitor terminal voltage—ideal for systems where every amp matters. Manual control override gives you flexibility when automation isn't enough. Built for high-output alternators and demanding marine applications.
