ARCO Marine Zeus 48V 8kW J180 4 in. Alternator with Isolated Ground

The ARCO Marine Zeus A8000-48V is an 8kW alternator with an isolated ground, designed for high-energy production in marine, RV, military, and commercial applications. Unlike units that adapt 12V rotors, this alternator utilizes a native 48V rotor and field current for increased efficiency and cooler operating temperatures. Its performance is optimized for low-RPM output, making it effective for charging large battery banks and reducing reliance on traditional generators.

Key Features and Specifications:

• Output: Sustains up to 78 Amps (4,173 Watts) at 2,500 RPM and reaches peak output of 180 Amps (9,360 Watts) at 9,000 RPM.
• Mounting: J180 4 in. saddle-style mount, commonly replacing Volvo Penta and industrial-based engines.
• Design: Features dual cooling fans, an externally mounted rectifier, and heat-shedding E-Coat/Cerakote finish for durability.
