Blue Sea Systems ML-ACR Automatic Charging Relay with Manual Control - 12V DC 500A
Model: 7622-BSS
Automatically manages the charging of two large battery banks
Allows paralleling of battery banks for emergency starting
500 Ampere continuous rating to support high-output alternators
Magnetic Latch (ML)—ACR draws very low current (<40mA to monitor terminal voltage) in the "ON" or "OFF" states, and draws moderate current for very short time when changing state
Dual sensing—senses charge on both battery banks
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
Senses charging on two battery banks
Manual control switch provides an added level of safety allowing control with or without power, and offering LOCK OFF capability for servicing
500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine
