ARCO Marine Zeus A275L J-180 4" Alternator with Regulator

The ARCO Marine Zeus A275L J-180 4" Alternator with Regulator is a top-tier power solution designed for high energy production. This alternator is engineered to deliver the highest power output in its size and class, making it an ideal choice for marine, RV, military, and commercial applications. With its rapid charging capabilities, it efficiently powers large battery banks, ensuring a reliable energy source for your vessel or equipment.

Unmatched Performance and Durability

The Zeus A275L J-180 stands out for its exceptional performance and durability. It operates at the coolest temperatures compared to other alternators in its category, thanks to advanced heat-shedding coatings, a refrigerator on the housing exterior, dual cooling fans, and OEM components. This not only enhances its performance but also extends its lifespan. The alternator is optimized for performance at idle speeds, reducing the need for a generator and creating additional power with your engine. Additionally, the E-Coat/Cerakote coating absorbs less heat, allowing for more amperage and sustained periods of operation. To maximize performance, it is recommended to use an ARCO Zeus Bluetooth alternator regulator or lithium battery charging systems.

Technical Specifications and Practical Applications

The ARCO Marine Zeus A275L J-180 4" Alternator with Regulator offers a range of technical specifications that make it a versatile and reliable choice. With a 12v voltage, 16 rotor poles, and a stator size of 138mm, it is designed to replace most Volvo Penta alternators using a 4” J180 saddle-style mount. The alternator boasts a maximum output of 311 Amps at 9,000 RPM and a sustained cruising output of 227 Amps at 6,000 RPM. Its internal/external regulation and 14.1v output voltage ensure optimal performance. This high-quality alternator is SAE J1171 Certified and proudly made in the U.S.A., making it a perfect fit for those seeking top-notch performance and reliability. Whether you are a marine enthusiast, an RV owner, or a professional in the commercial sector, the Zeus A275L J-180 is the ultimate power solution for your needs.
