The A275L-12-N62-IE-49K6CP model provides exceptional electrical output and precise voltage regulation, ensuring reliable performance for your vessel’s systems. Designed for marine-grade durability and efficiency, this alternator is an ideal choice for boaters seeking robust, long-lasting power solutions to tackle the challenges of the open water.
- Engineered for High Energy Production.
- Optimized for performance at idle speeds.
- Rapidly charges large battery banks.
- High-density, ultra-efficient stator winding
produces maximum energy output. - 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
- Unleash peak performance with E-Coat/ Cerakote. Our advanced coating dissipates heat, keeping the A275L cooler. This translates to more amperage for
sustained periods. - For maximum performance or lithium battery charging, use an ARCO Zeus Alternator Regulator.
- SAE J1171 Certified.
