Zeus A275L N62 Alternator with Clutch Pulley & 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, and OEM Components.
• It is 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 A275L cooler. This translates to more amperage for sustained periods.

The ARCO Marine Zeus A275L N62 High-Performance Alternator is a 12V unit designed for demanding power requirements in marine, RV, military, and commercial applications. This alternator is engineered for superior energy production, providing a maximum output of 311 Amps at cold, 9,000 RPM, and sustained outputs of 227 Amps at 6,000 RPM and 198 Amps at 3,000 RPM. Its design focuses on efficient power delivery and thermal management, operating 8-20% cooler than traditional alternators through heat-shedding coatings and dual cooling fans. This feature helps maintain performance during extended operation and reduces the need for an auxiliary generator by maximizing output at idle speeds. The A275L-12-N62-EX-50K6CP is compatible with ARCO Zeus Bluetooth alternator regulators for optimized performance and is SAE J1171 certified for safety. It fits Mercedes Sprinter models from 1999-2006 and can replace the dual alternator setup in 2007 and newer models, making it suitable for specific vehicle upgrades or replacements.
