Zeus A4000-24V Low Turn On (LTO) High Output Alternator

ARCO MARINE Zeus A4000-24V Low Turn On (LTO) High Output Alternator

High Output / High Amperage Alternator: The Highest Power Output in Its Class
24V Advantage - Low Turn On (LTO)
The ARCO Zeus A4000-24V LTO alternator turns on at lower RPMs, runs cooler and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM, and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!
Best-in-Class Performance
The ARCO Zeus A4000-24V alternator turns on at lower 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.
Choose A4000-24V LTO if:
You prioritize charging at idle (at campsite or anchor)
You need to limit power take-off i.e. smaller engine
You are willing to trade some top-end output for increased output
