Arco Starting & Charging 4604 Zeus A8000-48V 8kW N62 Marine Alternator with Clutch Pulley

The ARCO Zeus A8000-48V 8kW N62 alternator with clutch pulley is a high-output 48-volt alternator engineered for high energy production. It is suitable for marine, RV, military, and commercial applications and charges large battery banks quickly.

The Zeus A8000-48V uses a native 48V rotor and field current rather than a 12V rotor adapted for 48V use. According to the manufacturer, this lets the alternator run cooler than competing 48V alternators, which has a direct impact on its lifespan.

Key Features:

• Engineered for high energy production and rapid charging of large battery banks
• Optimized for performance at idle speeds
• Reduces the need for a generator by creating additional power from your engine
• Heat-shedding coatings, a rectifier located on the housing exterior, dual cooling fans, and OEM components for cooler operation
• E-Coat/Cerakote finish to help keep the alternator cooler for sustained amperage output
• Works with the ARCO Zeus Bluetooth Alternator Regulator for maximum performance or lithium battery charging
• SAE J1171 certified
