ARCO Marine Zeus A225S Vortec Alternator w/Terminal Block CWR

Zeus A225S Vortec Alternator with Terminal Block

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.
