- 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.
