Description
rr
Alpha Compact 28/150 VP for Volvo Penta Engines.
rr
Alpha Compact alternators are optimised to deliver continuous high power output in energy storage applications. Combined with Mastervolt Alpha Pro regulators, they create a high performance, plug-and-play charging solution. This combination is suitable for all battery types, including Lithium Ion.
rr
These automotive style alternators offer many advantages. Most manufacturers offer a second alternator option, better known as PTO or Power Take Off option. This provides a straight-forward way to add an Alpha Compact as a second alternator. Alternatively, the stock alternator can be replaced with an Alpha Compact to obtain a powerful, MasterBus enabled 3-step charger.
rr
Compared to conventional alternators, Alpha Compact offers lower weight, smaller dimensions and reduced fuel consumption. This is made possible by its open construction with double internal fans. An integrated temperature sensor controls the operating temperature.
rr
The Alpha Compact VP alternators are fitted with a multi-groove pulley as standard (Mastervolt 48420170). Other Alpha Compact models come without pulley. Mastervolt offers a complete range of multi-groove pulleys.
rr
Applications: Worldwide use in marine, mobile, infrastructure and industrial applications.
