Key Benefits & Specifications:

• Robust Power Output: Delivers a rated 4kW of power, with a sustained cruising output of 5.1kW PTO (3,575 Watts / 130 Amps) and a maximum output (cold, 9,000 RPM) of 5.7kW PTO (3,960 Watts / 144 Amps).
• Low Turn On (LTO) Design: Generates power at just 1,072 Alternator RPM, providing over 1.4kW (51 Amps) at under 1,500 RPM. A marine diesel engine idling at 750 RPM with a 2:1 pulley ratio can generate over 1.5kW (55 Amps).
• Enhanced Cooling & Durability: Features a native 24V rotor and field current, dual cooling fans, heat-shedding E-coating, and an external rectifier for significantly cooler operation and extended alternator lifespan.
• Isolated Ground: Provides critical protection against stray current corrosion, essential for marine electrical systems.
• Certified Safety & Quality: SAE J1171 Certified for ignition protection, ensuring compliance with US Coast Guard requirements for gasoline engine applications, and proudly made in the U.S.A.
• Versatile Application: Suitable for a wide range of uses including marine, RV, military, and commercial power systems.
• Rapid Battery Charging: Engineered for high energy production to rapidly charge large battery banks, reducing reliance on a separate generator.
• Compact & Lightweight: Weighs only 15.89lbs (7.2kg), offering a powerful solution in a manageable package.

Compatibility & Pairings:

• Replaces Mando-type alternators utilizing Vortec/GM pad mounting feet.
• Commonly found on many Mercruiser and Volvo Penta 3.0GLM, 3.0GLP, 4.3GXi, 5.7GiL, and 5.7GXiL Marine Engines.
• Optimize performance and facilitate lithium battery charging by pairing with the ARCO Zeus Bluetooth Alternator Regulator (sold separately).
