Features

Blue Sea Systems ML-ACR Automatic Charging Relay - 12V DC 500A

Model: 7620-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

500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine
