Description

The Mastervolt Alpha Compact 14/200 is a high-output 12 volt, 200 amp automotive-style alternator supplied as standard with the Alpha Pro III charge regulator and a multigroove pulley. Together they form a plug-and-play, MasterBus-enabled three-step charging solution optimised for continuous high power output and suitable for all battery types, including lithium ion.

Its open construction with double internal fans and an integrated temperature sensor makes it up to 40 percent lighter and 25 percent more compact than a conventional alternator, with up to 30 percent lower fuel consumption and a strong 106 A even at 1800 rpm. It can be added as a second (Power Take Off) alternator or fitted in place of the stock unit. The cable and electronics are protected against oil, moisture and dirt, and it is built to original equipment quality with a full two-year warranty.
