Automatic Charging Relay "ACR" 

Automatic Charging Relay "ACR"

Blue Sea System SI-Series Start Isolation Automatic Charging Relay automatically isolates batteries during starting to protect sensitive electronics and manages the charging of two battery banks. The 120 AMP continuous rating supports the high-output alternators. LED light indicates when batteries are combined and blinks when the undervoltage or starting isolation feature is engaged.
