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
