ARCO Zeus A275L High Output Alternator

Description

THE HIGHEST POWER OUTPUT ALTERNATOR IN ITS SIZE/CLASS

• 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:
  • Heating shedding coatings
  • Rectifier located on housing exterior
  • Dual cooling fans
  • OEM Components
• Optimized for performance at idle speeds
• Reduces need for 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
• For maximum performance or lithium battery charging, use an ARCO Zeus Bluetooth alternator regulator
• SAEJ1171 Certified
• Proudly made in the USA

REGULATION

External Only (EX): These units will come with a terminal block and a P-Type harness. They will only work with an external regulator, such as an ARCO Zeus Bluetooth alternator regulator.

Internal/External (IE): Internally regulated with adaptor for optional external regulation.

TRANSPARENCY – HOW WE TEST FOR OUTPUT

To measure sustained output, the alternator is run at 3,000 RPMs for 60 minutes with a plexiglass shield covering the units. Testing shows that after 60 minutes in these conditions, alternators reach their maximum operating temperature, or the conditions under which the unit will produce the least output.

It is under these harsh conditions where we measure the “hot” output of the units at various RPMs. The complete power curve is shown above.

Note: The “hot” conditions are much less favorable than the conditions typically used in the industry. The temperature of the stator during our “hot” test was 305°F. Incumbents measure the power curve at an ambient temperature of 140°F. “Cold” testing was done at 71°F.
