Blue Sea SI-ACR 120A Automatic Current Limit Relay
SI-ACR AUTOMATIC CURRENT LIMIT RELAY – 12/24 V DC 120 A
Connects batteries to each other during charging and isolates them while discharging and engine start up.
FEATURES
• Protects sensitive electronic devices by isolating the current-using equipment momentarily from the motor’s start-up circuit as it is started
• Suitable for both 12 V and 24 V systems
• Automatic voltage selection (12/24 V)
• Hermetically sealed contacts; protected from gases and vapor
• Protected against arcing — also safe for boats with gasoline-powered engines
• Supports high-performance chargers max 120 A
• Two detection circuits
OPTIONAL FEATURES
• Start-up isolation disconnects current-using equipment from the motor's start-up circuit during start-up and protects devices during voltage spikes and dips
• Remote installed LED indicates the ACR status – LED sold separately
TECHNICAL SPECIFICATIONS
Nominal voltage: 12V DC | 24V DC
