Alpha Pro MB

The charge regulator measures the battery temperature and adjusts the charging process accordingly, resulting in a safe and fast charge. Therefore the battery is always kept in good condition.

  • Suitable for 12 and 24 V.
  • Including plug & play connection cable, an adapter cable for Bosch alternators is optional.
  • The Alpha Pro series is suitable for most alternators with a charging current of up to 400 amps.
  • Automatic voltage and temperature compensation.
  •  ‘Keep alive’ function for tachometer.
  • MasterBus compatible.

Alpha Pro: Easy to operate

Easy operation LEDs on the body of the charge regulator indicate the charge phase. The Alpha Pro is designed as a ‘fit all’ solution. Just one unit is needed for both 12 and 24 V applications, with a simple selector switch to set the regulator to the right voltage. The charge regulator can also be used on any other brand of alternator that has a standard Bosch connector, using a Bosch adapter cable (optional; product code 45510500). 

MasterBus connectivity

The Alpha Pro is compatible with MasterBus, allowing easy monitoring via a MasterView touchscreen. In a MasterBus system the voltage drop over the battery cable and the battery temperature is compensated automatically.

Benefits of a Mastervolt charge regulator

  • The Alpha Pro charge regulator maximises the output of Mastervolt Alpha alternators or any other alternator by regulating the alternator in a way that the batteries receive the optimum charge. The proven 3-step+ charge method used by all Mastervolt battery chargers guarantees fast and safe charging of your batteries.
  • The Alpha Pro helps to cut emissions by requiring less run time because it maximises the power from any alternator. A battery can be charged quickly even at very low RPM, especially when connected to an Alpha series alternator. By connecting the Alpha Alternator to a Battery Mate or battery isolator, several battery banks can be charged simultaneously.
  • Does your tachometer sometimes indicate zero while the engine is running? The ‘keep alive’ function of the Alpha Pro gets rid of this problem for ever.
