ARCO Marine Zeus 24V 7kW J180 4" Alternator w/Isolated Ground [4503]Zeus 24V 7kW J180 4" Alternator with Isolated Ground The ARCO Zeus 24v 7kW 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. In real world terms, a marine diesel engine at 1,500 RPM with a 2: 1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3. 21: 1 ratio

Zeus 24V 7kW J180 4" Alternator with Isolated Ground

The ARCO Zeus 24v 7kW 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. In real-world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio generates over 6kW!

The ARCO Zeus 24v 7kW 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.

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 onthe  alternator lifespan.
