SI-ACR Automatic Charging Relay - 12/24V DC 120A

7610

Automatically combines batteries during charging, isolates batteries when discharging and when starting engines
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
• Dual sensing

Optional Features

• Start Isolation allows temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics from sags and spikes
• Remote LED remotely indicates ACR states - requires optional LED
