Mastervolt Marine alternator 24 V 75 A with multi-groove pulley

24 V, 75 A alternator with multi-groove pulley, designed to deliver stable charging and reliable operation in on-board electrical systems.

This 24 V, 75 A alternator with multi-groove pulley is intended to provide continuous, stable and efficient charging on vessels that require a robust power system. Its compact design and marine-oriented construction guarantee safe operation even in demanding environments, where vibration, humidity and temperature changes are commonplace.

The multi-groove pulley transmits power with a larger contact surface, which is especially useful on engines fitted with poly-V belts that need to maintain rotational stability under high loads. Thanks to this architecture, the alternator improves mechanical transfer and promotes more uniform power generation.

As a reference from a previous generation, this model is usually supplied without an integrated regulator, which allows existing units to be replaced or the alternator to be integrated into systems that already have the corresponding regulator. Its manufacture is geared towards maximising durability, with components designed to resist corrosion and a stator capable of delivering a constant current output during hours of navigation.
