alpha pro ii

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 12v and 24v
  • including plug & play connection cable, an adapter cable for bosch alternators is optional
  • automatic voltage and temperature compensation
  • masterbus compatible

alpha pro mb: easy to operate
easy operation leds on the body of the charge regulator indicate the charge phase. the alpha pro mb 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).

masterbus connectivity
the alpha pro mb 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 mb charge regulator maximizes 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 mb 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.
