ARCO Launches Zeus A8000-48V: The Next Generation High-Output Alternator

48V ON CATAMARAN AND SAILBOAT

Pensacola, FL – 2/25/2025 – ARCO is proud to announce the launch of the Zeus A8000-48V, the latest innovation in high-output alternators. Designed with a native 48V rotor, this cutting-edge alternator offers superior efficiency, cooler operation, and unparalleled power generation compared to traditional 48V models.

Revolutionary Performance
The Zeus A8000-48V alternator is engineered to turn on at lower RPMs while delivering greater power output than its larger, heavier counterparts. It consistently generates over 3kW (55 Amps) at 2,500 RPM, and nearly 6kW (111 Amps) at 4,000 Alternator RPM.

In real-world applications:

  • A marine diesel engine operating at 1,200 RPM with a 3.13:1 pulley ratio produces over 5kW (97 Amps).
  • A Mercedes Sprinter at 750 RPM with a 3.21:1 pulley ratio generates over 3kW (55 Amps).

True 48V Efficiency
Unlike many competitors who modify 12V rotors for 48V applications, ARCO’s Zeus A8000-48V utilizes a native 48V rotor. This not only maximizes efficiency but also prevents excessive field current reductions, ensuring optimal performance at all RPM levels. The result? A cooler-running alternator with enhanced longevity, providing reliable power without the risk of component failure.

“Our customers have been asking for a 48V offering with the same build quality they’ve come to expect from ARCO Zeus. What they did not expect was such a great performer, easily outclassing the competition while using the same footprint as our 12V/24V products,” said Chris Witzgall, VP of Sales at ARCO. “We couldn’t be more excited to bring this level of innovation to the market and see how it transforms 48V power solutions.”

The Zeus A8000-48V is now available through ARCO’s authorized distributors and partners. For more information, visit the A8000-48V page here or contact sales@arcomarine.com
