mastervolt.us ALTERNATORS & REGULATORS 102 Alternators and Charge Regulators: For rapidly recharged batteries The existing alternator on the main engine is designed to charge the starter battery. As a result the combination is not ideal for fast and full charging of other batteries, especially if you want to charge the batteries over a short time or when powering a heavy load. There are two options to solve this issue: Equip the standard alternator with a Mastervolt Alpha Pro charge regulator. This charge regulator maximizes the output of alternators by regulating the alternator in a way that ensures the batteries receive the optimum charge. The proven 3-step+ charge method guarantees fast and safe charging of your batteries. You can also choose a powerful second Mastervolt Alpha alternator with Alpha Pro charge regulator. This combination was specifically designed for charging service batteries, and allows you to charge quickly and turn off your engine when you want. Alpha Pro Charge Regulators • Suitable for 12V and 24V • Including plug & play connection cable, an adapter cable for Bosch alternators is optional • The Alpha Pro series is suitable for alternators up to 400A charge current • Automatic voltage and temperature compensation • ‘Keep alive’ function for tachometer • MasterBus compatible 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. Alpha Alternator Series • Fast and complete charging of all batteries • Power supply for all consumers • 12V and 24V versions • 75A to 200A charge current • As standard, delivered with Alpha Pro MB charge regulator for an optimal performance and longer-lasting batteries Using a Battery Mate, Charge Mate or BI battery isolator in conjunction with an Alpha Alternator, makes it possible to easily charge two or three separate battery banks simultaneously. Alpha Compact Alternator Series Alpha Compact “automotive style” alternators provide an easy fit on factory-installed PTO (power take-off) brackets available from most engine manufacturers. If space is limited, Alpha Compact can also be used to exchange the stock alternator for a more powerful model. • Plug and play solution, with Alpha Pro III regulator included. • Up to 40% lighter and 25% more compact than conventional alternators • Up to 30% lower fuel consumption • OEM quality with optimized material composition • Suitable for use in high temperature areas • Cable and electronic parts protected against oil, moisture and dust • Engine RPM signal • Wide range of accessories available • Models with suffix “VP” are a perfect fit for Volvo Penta engines A second alternator on the main engine, combined with a larger battery bank and inverter, could be an alternative for a generator.
