ML-ACR Automatic Charging Relay - 12vDC 500A

The ML-ACR Automatic Charging Relay is engineered for serious marine power systems. This 12VDC relay automatically manages charging between two large battery banks, connecting them when your alternator is running and isolating them when the engine shuts down. With a robust 500-ampere continuous rating, it handles high-output alternators without compromise. In emergencies, the relay allows instant paralleling of battery banks for emergency starting power when you need it most. The innovative Magnetic Latch design keeps current draw incredibly low—under 40mA in both ON and OFF states—so monitoring terminal voltage won't drain your batteries. Ideal for dual-battery setups on fishing boats, cruisers, and offshore vessels where reliability and power management are non-negotiable.
