Better Technology = Better Performance

High Output / High Amperage Alternator: The Highest Power Output in Its Class

A8000-48V Advantage

The ARCO Zeus A8000-48V alternator turns on at lower RPMs, runs cooler and provides more power than other 48V alternators that are larger and heavier. This alternator continuously generates over 3kW (55 Amps) 2,500 RPM, and almost 6kW (111 Amps) at 4,000 Alternator RPM. Put in real world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!

True 24V Alternators

Instead of using rotors designed for 48 volts, many competitor’s alternators simply use their 12V rotors which is less efficient and limits output at all RPMs. In this scenario, your external smart regulator must drastically reduce field, by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitor’s 48V alternators, having a direct impact on the alternator’s lifespan.

  • Replace your noisy generator!
  • Engineered for high energy production.
  • Suitable for marine, RV, military, and commercial applications.
  • Rapidly charges large battery banks.
  • Coolest operating temperatures for increased performance:
    • Heat shedding coatings
    • Rectifier located on housing exterior
    • Dual cooling fans
    • OEM components
  • 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, keeping the high amp alternator cooler for sustained amperage output.
  • For maximum performance or lithium battery charging, use the ARCO Zeus Bluetooth Alternator Regulator.
  • Mercedes requires the use of a clutch pulley on secondary alternators used on all Sprinter vans. For Mercedes Sprinter, please use our N62 with Clutch Pulley here.
  • SAE J1171 Certified.
  • Proudly made in the U.S.A.

Mounting Options and Applications

Mounting ARCO Part Number Application
1-2” Single Foot 4505 Replaces most domestic styles using a single 1or 2”mounting foot (e.g., Motorola, Prestolite).
3.15” J180 Saddle 4501 Replaces most small case styles using a 3.15” J180 saddle style mount
(e.g., Hitachi, Lucas, Mitsubishi) Most Yanmars.
3.15"R Saddle Mount, Rear Exit B+ 4502 Must Be Used on Yanmar Common Rail Engines Introduced after 2013 (JH-CR, 3JH40, 4JH45, 4JH57, 4JH80, 4JH110).
4” J180 Saddle 4503 Replaces most Volvo Penta alternators using a 4” J180 saddle style mount. Also use on many larger industrial-based engines.
Vortec/GM 4506 Replaces Mando type alternators using Vortec/GM pad mounting feet (Found on many Mercruiser and Volvo Penta 3.0GLM, 3.0GLP, 4.3GXi, 5.7GiL, 5.7GXiL Marine Engines).
N62 (Clutch Pulley) 4504 Replaces factory dual alternator on many Sprinter RVs, including Roadtrek, Thor, Winnebago, and others.
For all Mercedes Sprinter applications with N62 option.
Meets current Mercedes Upfitter weight and PTO requirements.
Isolated ground only for marine units.

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.

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.
