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

1) Condition: Engine starting

  • Relay is open isolating batteries
  • Batteries are isolated to protect sensitive electronics from voltage sags and spikes

2) The maximum current a switch is designed to conduct for an indefinite period.

3) The maximum amount of current a switch is designed to carry for a minimum of a designated period of time.

4)  As a safety feature, some ACR's prevent combining into a severely discharged battery. A dual-sensing ACR will monitor the voltage on both batteries and will not connect if either battery is below the under voltage lockout level. Use caution when combining into a battery with extremely low voltage, because this might represent a faulty battery or a problem elsewhere in the system.
