Description

If Optimal Charging at Fast Idle or at Higher RPMs Is Important to You, this is the Perfect Alternator for You

 

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

 

Note: If low speed charging is important to you, view our ARCO Zeus 24V 4kW Low Turn On (LTO) Alternator here.

24V 7kW Advantage

The ARCO Zeus 24V 7kW high amp alternator generates over 3kW at just under 3,000 alternator RPM, and almost 6kW at under 6,000 RPM. To put in real world terms, a marine diesel engine idling at 1,500 RPM with a 2:1 pulley ratio is generating over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio is generating over 6kW!

Best-in-Class Performance

The ARCO Zeus 24v 7kW alternator turns on for fast idling or at mid to higher RPMs, runs cooler and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Cost and Weight Savings

In applications like boats or Sprinter vans, adopting a 24V system reduces wiring costs and overall weight compared to 12V systems, making it a practical choice for improving efficiency and lowering operational expenses. Due to source field voltage our 24V alternator runs cooler than other 24V alternators that use 12V field. This extends the life of our alternator by not overheating.

ARCO Zeus 24V High Amperage Alternators, 4kW LTO or 7kW: Which One's Right for You?

Choose 7kW if:

  • You primarily charge at cruising rpm or on the road
  • Your battery bank is larger, and you have heavy loads
  • You only charge every other day when moving to a new location

If these do not apply to you, check out the 4kW LTO page here.

  • 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/Cerakote, 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.

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.
