ARCO Marine Zeus A225S 3.15 Alternator with Case Ground and Terminal Block

Zeus A225S 3.15 Alternator with Case 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.


• SAE J1171 Certified.


• Models are available with an internal/external voltage regulator.
