Blue Sea Systems SI-ACR Automatic Charging Relay with Start Isolation

The Blue Sea Systems SI-ACR Automatic Charging Relay with Start Isolation automatically combines batteries during charging and isolates batteries when discharging and when starting engines. Start Isolation (SI) protects sensitive electronics by temporarily isolating house loads from engine circuit during engine cranking protects house circuit from voltage sags and spikes

Features:

• Automatically combines batteries during charging
• Automatically isolates batteries when discharging and when starting engines
• Allows temporary isolation of house loads from engine circuit during engine cranking to protect sensitive electronics start isolation (SI) indicated by blinking LED
• Supports high-output alternators up to 120 Amps
• Ignition protected safe for installation aboard gasoline powered boats
• LED light is On when batteries are combined
• Under voltage lockout will not close when lower battery is below 9.5 Volt @ 12 Volt System or 19 Volt @ 24 Volt System lockout indicated by blinking LED
• Hermetically sealed contacts, vapor-proof
• Dual Sensingsenses charge source on either battery bank
• Designed for 12 or 24 Volt systems 12 / 24 Volt auto-ranging voltage input
• Remote LED output indicates relay state away from ACR unit
