Blue Sea 7622 ML-Series Heavy Duty Automatic Charging Relay

Manage charging across two battery banks with the Blue Sea Systems 7622 ML-Series automatic charging relay. For boat owners using high-output alternators, it combines a 500-amp continuous rating with manual control and configurable isolation of engine and house circuits.

Key features

• Operate the manual switch with or without power, or lock it off for servicing.
• Monitor charging at both battery banks while drawing less than 10 mA to sense terminal voltage in the ON and OFF states.
• Configure Start Isolation to separate house loads from the engine circuit during cranking, helping protect sensitive electronics.
• Configure Engine Isolation to separate two running engines, helping protect engine electronics and maximize alternator output.
• Use the LED output for remote indication of combined, isolated, voltage lockout, Start Isolation or Engine Isolation status.
• Connect multiple cable terminals to the extended studs; tin-plated copper provides conductivity and corrosion resistance.
