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 A4000-24V Low Turn On (LTO) Alternator here.

24V 7kW Advantage

The ARCO Zeus A7000-24V alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM, and almost 6kW (218 Amps) at under 6,000 RPM. To put in real world terms, a marine diesel engine 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 A7000-24V alternator turns on for cruising 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.

True 24V Alternators

Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact on alternator lifespan.

ARCO Zeus 24V High Amperage Alternators, A4000-24V LTO or A7000-24D: Which One's Right for You?

Choose A7000-24V if:

  • You primarily charge at cruising rpm or on the road
  • You only charge every other day when moving to a new
    location
  • You are willing to trade low RPM output for class-leading output at
    mid to high RPMs

*On the power curve graph, select A4000-24V LTO for use cases left of the Decision Point; otherwise, select A7000-24D.

 

Here’s a concise comparison of the DF315, DF4, and SF12 ARCO Zeus alternator mounting configurations:

Mount Code Mount Type Foot Style Foot Spacing Common Use Notes
DF315 Dual Foot (Yanmar-style) Dual 3.15 inches (80 mm) Yanmar marine engines Stable, compact mount for tight bays
DF4 Dual Foot (J180-style) Dual 4 inches Heavy-duty marine and industrial engines Rigid, robust mounting
SF12 Single Foot (Universal, Delco Style) Single 1" or 2" (adjustable) Flexible marine/automotive applications Adapter allows fit to multiple brackets
  • DF315 is ideal for Yanmar-style brackets.
  • DF315R is ideal for Yanmar-style brackets. R = Rear Battery Post 
  • DF4 is suited for larger, more robust engine frames.
  • SF12 offers the most flexibility and is often used in retrofits or tight spaces.
