Blue Sea Systems 7610 SI-ACR Automatic Charging Relay - 12/24V DC 120A

Blue Sea Systems 7610 SI-ACR Automatic Charging Relay - 12/24V DC 120A

SI-ACR Automatic Charging Relay - 12/24V DC 120A, rated 120A continuous. Start Isolation allows temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics from sags and spikes.

Features:

• Protects sensitive electronics by temporary isolation of house loads from engine circuit during engine cranking
• Designed for 12 or 24 volt systems
• 12/24 volt auto ranging voltage input
• Hermetically sealed contacts/vaporproof
• Ignition protected—safe for installation aboard gasoline powered boats
• Supports high-output alternators up to 120 Amperes
• Remote LED remotely indicates ACR states - requires optional LED

Installation Notes:

• Terminal Stud Torque: 140 in-lb (15.82 Nm)
• Cable Size to Meet Ratings: 1/0 AWG

Why Choose This Charger?

• Charges from the boat's own DC system, with no inverter and no shore power
• Keeps phones and electronics alive without a cigarette-lighter adapter hanging loose
• A finished, flush fitting rather than an accessory plugged into a socket
• Built and sealed for the cockpit, not for a car dashboard
