The Mastervolt Alternator Alpha 24/95 Compact produces direct current (DC) for your 24V on board system to charge batteries (starter, service or bowthruster) fast and complete through its three-stage charge characteristic. This alternator can be installed on any engine type. A charge regulator Alpha Pro (24V) (three-stage) is included and achieves maximum yield from minimum engine hours. A loss in voltage due to wiring and/or battery isolator is automatically compensated for.
