Description

The ARCO Zeus A8000-48V alternator is a high-output, high-amperage alternator for marine, RV, military, and commercial applications. It features a native 48V rotor for increased efficiency and cooler operation. It continuously generates over 3kW (55 Amps) at 2,500 RPM and almost 6kW (111 Amps) at 4,000 Alternator RPM. Key features include heat-shedding coatings, an exterior rectifier, dual cooling fans, and OEM components. Optimized for performance at idle speeds, it reduces the need for a generator. It is SAE J1171 Certified and made in the U.S.A.
