Alpha Compact 14/120
Delivery includes Alpha Pro III charge regulator.
Alpha Compact alternators are optimized to deliver continuous high power output in energy storage applications. Combined with our Alpha Pro regulators, they create a high performance, plug-and-play charging solution. This combination is suitable for all battery types, including Lithium Ion.
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 3-step charger.
High performance plug & play alternators
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.
The Alpha Compact series consists of 4 models in 12 V and 24 V. Special models for Volvo Penta engines are under development. Finding the right alternator for a specific application can be complicated. Please feel free to contact Mastervolt for assistance, we are happy to help you.
Freewheeling multigroove pulleys are available in various diameters and widths for an optimal pulley ratio and belt alignment. Exception to the rule is the Alpha Compact 14/200, which comes with a multigroove pulley as standard.
Isolation bushings - the negative pole of Alpha Compact alternators connects to the housing. Isolated operation is possible by installation of isolating bushings.
Modern Euro 5/6 engines include an auto start/stop system. Multiple solutions are available to detect a running engine.
