The ACR 12/24 Isolation Relay (Blue Sea Systems SI-ACR) automatically connects two battery banks as soon as a charging source – such as the alternator – supplies voltage, and disconnects them again as soon as charging ends or consumers draw more current than is being supplied. With a continuous current of 120 A, it is also suitable for onboard electrical systems with powerful alternators.

Advantages

  • Automatic, voltage-dependent, and time-delayed connection of two battery banks for joint charging
  • Supports high-output alternators with a 120 A continuous current rating
  • Optional start isolation separates house loads from the engine circuit during starting
  • Integrated LED for status display, optional remote LED available
  • Side and bottom cable entries, and removable terminal covers for flexible installation
  • Connection studs for multiple cable lugs simultaneously

Technical Data & Compatibility

  • Continuous current 120 A, intermittent current 210 A (5 minutes)
  • Automatically detecting input voltage 12 V / 24 V DC
  • Combine voltage 13.0 V (2 min.) / 13.6 V (30 sec.), disconnect voltage 12.75 V (30 sec.) / 12.35 V (10 sec.)
  • Undervoltage lockout 9.5 V / overvoltage lockout 16.0 V DC (12V operation)
  • Cable cross-section 1 AWG (50 mm²), max. 1/0 AWG; connection studs 3/8"-16 (M10)
  • Protection class IP67, UL 1500, ignition protected according to ISO 8846 and SAE J1171

When do I need an isolation relay like the ACR 12/24?

As soon as two battery banks are to be charged via a common alternator without affecting each other during discharge – for example, the starting and house battery in a boat, RV, or commercial vehicle. Thanks to its 120 A rating, the ACR 12/24 is also sufficiently dimensioned for more powerful alternators and larger house batteries.
