Mastervolt Alternators and Charge Regulators For rapidly charged batteries The Mastervolt Alpha alternator with Alpha Pro MB charge regulator were specifically designed for charging service batteries, and allows you to charge quickly and turn off your engine when you moor. For all engine types Alpha alternators are equipped with several fixations for customised alternator brackets, available from your installer or engine supplier. Some engine brands come with Mastervolt alternator brackets as an option. Performs above 40°C Forced cooling via the ventilator action of the pulley provides a lot of power in higher temperatures, even in enclosed engine rooms where the temperature can easily rise above 40°C. Multi-belt pulley The 12/130 and 24/75 models are also available with a multi-belt pulley. Alpha Pro MB charge regulator: Easy to install The Alpha Pro MB charge regulator is designed as a ?fit all? solution, just one unit is needed for both 12 and 24V 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. Fast charging, even at a stationary rpm Standard alternator only supply the specified capacity at a high rpm. The Mastervolt Alpha generator was specifically designed to charge powerfully, even with a low engine rpm. Mastervolt Regulator - Alpha Pro MB Charge Regulator Features: - Suitable for 12 and 24V - Plug and play connection cable included, also for Bosch alternators - Automatic voltage and temperature compensation - MasterBus compatible - The charge voltage is automatically adjusted if there is any risk of gas formation - Electronics permanently regulate the voltage, ensuring that the battery is always kept in good condition 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 forever.
