GENERATE

The Alpha Pro comes standard

with connection cable and

battery temperature sensor.

Benefits of a Mastervolt Charge Regulator

n

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.

n

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.

n

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.
