ARCO Marine Zeus A225S High Output Alternator with Regulator

The Zeus A225S is the highest power output alternator in its class, designed specifically for demanding marine environments.

Key Features:

• Engineered for high energy production, ideal for marine, RV, military, and commercial applications.
• Rapid charging capabilities for large battery banks.
• Operates at cooler temperatures, running 8 - 20% cooler than standard alternators due to advanced heat shedding coatings, external rectifier, and dual cooling fans.
• Optimized performance at idle speeds and reduces the need for generators by generating additional power while the engine runs.
• Utilizes E-Coat/Cerakote technology to minimize heat absorption, providing sustained amperage output.
• Compatible with ARCO Zeus Bluetooth alternator regulator for maximum performance and lithium battery charging.
• SAE J1171 Certified and proudly made in the U.S.A.
