Blue Sea Systems Si-Acr Automatic Charging Relay - 12/24V Dc 120A

Features

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

  • 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
