    Sterling ProReg-B Universal Advanced Digital Alternator Regulator

    The Sterling ProReg Advanced Regulator converts an alternator from a constant voltage battery charger to an efficient 4-step progressive constant current battery charger. Because of this improvement in the alternator control system, these regulators dramatically enhance the alternator's charge rates by between 200-2000%, depending on how effective the original system is. The Sterling Regulator is designed to charge batteries as fast as possible and to their maximum capacity without damage to the batteries or alternators.

    The Sterling ProReg-D Advanced Regulator is for use on alternators rated up to 400 amps. For smaller alternators rated up to 90 amps, and where an alternator temperature sensor, 24 volt operation, and the option of a remote display are not required, see the ProReg-B Regulator.

    Please note: If you have an integrated engine management system, it can interpret the Advanced Regulator's increased voltage as an alternator fault. These systems are rare on boats, but can be found on some motorhomes.  Also, installation of the Advanced Regulator often requires soldering a wire to the alternator brush connection. This is not difficult, but requires dismounting the alternator and access to a soldering iron. Use an Alternator to Battery Charger or a Battery-to-Battery Charger for applications where an Advanced Regulator is not appropriate.

    Sterling ProReg-D Features:

    • Maintains maximum performance of an alternator’s power curve.
    • Batteries charge 2-20 times faster, depending on original system efficiency.
    • Enables 25-35% extra useful power to be stored in batteries. A conventional alternator will only charge the battery to a maximum of about 75% of capacity; advanced regulators can acheive a 100% charge.
    • Battery plates receive less sulphate damage, resulting in longer life.
    • Built in safety features will switch the regulator off in case of an incorrect installation or other fault.
    • Reduces engine run time when charging batteries.
    • Compensates for voltage drops resulting from long cable runs, ammeters, diodes and other general wiring-related problems.
    • Software controlled slow start to avoid heavy loads on engine start.
    • Original regulator can be left in place as a parallel standby /failover.
    • Selectable for four battery types.
    • Fits 99% of alternators.
    • Self-diagnosing.
    • Battery temperature sensor with 1 meter cable.
    • Alternator temperature sensor disengages charger if an overheat situation occurs.
    • LED display.
    • High alternator or battery voltage trip.
    • Battery is protected if regulator or sense wire fails.
    • 12 or 24 volt operation.
    • For use on alternators rated to 400Amps.
    • Size: 180mm x 90mm x 55mm, 0.5 kg.
    • Optional remote control (170mm x 90mm x 40mm)..
    • 2 year warranty.
