Zeus A225S 3.15 Alternator with Isolated Ground (Common Rail) & 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, running 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 for sustained amperage output.
• Use the ARCO Zeus Bluetooth Alternator Regulator for maximum performance or lithium battery charging.
