Blue Sea 7622-BSS 12V DC Automatic Charging Relay - ML-ACR with Manual Control

The Blue Sea 7622-BSS 12V DC Automatic Charging Relay - ML-ACR with Manual Control is designed to automatically manage the charging of two large battery banks and allows paralleling of battery banks for emergency starting. With a 500 Ampere continuous rating to support high-output alternators, this relay is perfect for heavy-duty applications. The Magnetic Latch (ML) ACR draws very low current (<40mA to monitor terminal voltage) in the "ON" or "OFF" states and draws moderate current for a very short time when changing state. Dual sensing senses charge on both battery banks, while Start Isolation (SI) can be configured for temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics. Engine Isolation (EI) can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator output. The manual control switch provides an added level of safety allowing control with or without power and offering LOCK OFF capability for servicing.

With a 500 Amp magnetic latching (bi-stable) relay, this product automatically combines batteries during charging and isolates batteries when discharging and when starting the engine. It comes with a SPDT Remote Control Contura Switch - ON-OFF-ON.
