High performance alternator for marine and commercial applications
The ARCO Alternator A225S Series is engineered for high energy production, making it suitable for marine, RV, military, and commercial applications. With a robust output of 254 amps at 9000 RPM, this alternator is designed to rapidly charge large battery banks while maintaining optimal performance at idle speeds. Its advanced E-Coat or Cerakote finish absorbs less heat, allowing the A225S to operate 8 to 20 percent cooler than traditional alternators, which enhances its reliability and efficiency.
This alternator features a 6-groove 49 millimeter K6 belt and operates at 12 volts, ensuring compatibility with a wide range of systems. The external regulator and 4-wire configuration provide flexibility in installation, while the SAE J1171 certification guarantees compliance with industry standards. The small frame and side mount M8 thread battery post facilitate easy integration into various setups, making it a versatile choice for demanding environments.
ARCO has a long-standing reputation for dependability, having set the gold standard for marine engine parts nearly 60 years ago. Each unit is rigorously tested beyond normal operating conditions to ensure the highest quality and performance.
