    Zeus 24V 7kW J180 4" Alternator with Isolated GroundThe 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.Features: Engineered for high energy production. Suitable for marine, RV, military, and commercial applications. Rapidly charges large battery banks.

    Zeus A8000-48V 8kW 3.15 Alternator with Isolated Ground (Common Rail)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) at 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)!Instead of using rotors designed for 48 volts, many competitor 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.Features: Engineered for high energy production. Suitable for marine, RV, military, and commercial applications. Rapidly charges large battery banks.

  • ARCO Marine Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator w/Isolated Ground (Common Rail) [4402] ARCO Marine Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator w/Isolated Ground (Common Rail) [4402]

    ARCO Marine ARCO Marine Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator w/Isolated Ground (Common Rail) [4402]

    Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground (Common Rail)The ARCO Zeus 24v 4kW 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)!The ARCO Zeus 24v 4kW 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.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 the alternator lifespan.Features: 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 cruising 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.
