This product is BRAND NEW.



Alpha Pro II Alternator Regulator, MFG# 45512000, controls Mastervolt Alpha alternators, along with Bosch and other brands using the Bosch connector. Offer efficient 3-stage charging and is controlled through the MasterBus system.

The charge regulator 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 unit can also be used on any other brand of alternator that has a standard Bosch connector, with a cable supplied as standard in the box. Easy operation LEDs on the body of the regulator indicate the charge phase.

The Alpha Pro MB is also fully connectable to the MasterBus CANBus system, allowing easy monitoring via a MasterView touch screen. In a MasterBus system the voltage drop over the battery cable will be compensated automatically, as well battery temperature, improving the charging time without having to install additional cabling.

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.
