    • Designed to provide field current to (2) alternators on the same engine, the Balmar MC-612-DUAL voltage regulator features a unique dual harness design that eliminates the complication of wire splicing
    • In addition, the MC-612-DUAL can be programmed to offer alternator temperature sensing at two alternators
    • The regulator initiates the charging process with a user-adjustable start delay that allows the engine and belts to warm up before the alterrnator applies horsepower load to the system
    • The regulator then gently ramps up to bulk charging voltage
    • The bulk charging mode is where the lion's share of aggressive charging output occurs
    • Once the requirements of the batteries being charged, the MC-612-DUAL regulator reduces charging voltage to absorption voltage, and later, to float voltage, where the charging system is able to supply enough charging current to replace whatever electrical load the vessel demands
    • The Max Charge uses a combination of timed and calculation-based segments to ensure that the regulator remains in each stage of charge for as little or as long is required in the bulk, absorption, and float stages
      • In other words, the regulator will remain in bulk charge for a mini - mum time period (12 minutes is standard)
      • At the end of that 12 minutes, the regulator considers a number of criteria
        • Whether target voltage has been achieved, if the regulator was able to maintain that voltage for a given time, and how hard the alternator has to work to maintain that voltage
      • When all criteria are met, the regulator will advance to the next charging stage
    • Like a smart shorepower charger, the MC-612-DUAL uses advanced software programming to provide individualized charging profiles, depending on the battery type being charged
    • By setting the regulator to the battery program for your battery type, you can rest assured that your batteries will receive optimal charging whenever your engine is running
    • Dual field outputs for dual alternator operation on a single engine
    • Selectable Programs:
      • Factory Default (Universal)
