ARCO Marine Zeus A225S Vortec Alternator w/Regulator

Zeus A225S Vortec Alternator with Regulator

The highest power output alternator in its size/class. 

Features:

• Engineered for High Energy Production.


• Suitable for Marine, RV, Military, and Commercial applications.


• Rapidly charges large battery banks.


• Coolest operating temperatures for increased performance. Runs 8 - 20% cooler than incumbent alternators due to:


• Heat shedding coatings


• Rectifier located on housing exterior


• Dual cooling fans


• OEM Components


• Optimized for performance at idle speeds.


• Reduces the need for a generator by creating additional power with your engine.


• Unleash peak performance with E-Coat/Cerakote. Our advanced coating absorbs less heat, keeping the A225S cooler. This translates to more amperage for sustained periods.


• For maximum performance or lithium battery charging, use an ARCO Zeus Bluetooth alternator regulator.


• SAE J1171 Certified.


• Proudly made in the U.S.A.
