BLUE SEA SYSTEMS 7620, is a 500 Amp magnetic latching (bi-stable) relay that automatically combines batteries during charging and isolates batteries during discharge and engine start.
Features
Includes ML-Series Remote Control Contura Switch PN 2146
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 connection voltage) in "ON" or "OFF" mode and draws moderate current for a very short time when state changes
Dual Sensing - senses charge on both battery banks
Start Isolation (SI) - can be configured for temporary isolation of house loads from the 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 charge on two battery banks
LED output to remotely indicate when batteries are combined, isolated, in voltage lockout, or in start or engine isolation
3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance
