ARCO Marine Zeus 24V 4kW Low Turn On Vortec Alternator with Isolated Ground - Model 4406

Zeus 24V 4kW Low Turn On (LTO) Vortec Alternator with Isolated Ground

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.

Competitors 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 competitors 24V alternators, having a direct impact on the alternator lifespan.

The ARCO Marine Zeus 24V 4kW Low Turn On (LTO) Vortec Alternator is engineered for high-performance applications, offering efficient power generation at low RPMs. Its design enables the alternator to turn on at just under 1,100 RPM, providing over 1.4kW (51 Amps) and nearly 2.4kW (87 Amps) at 2,000 RPM, making it suitable for marine, RV, military, and commercial use. This capability ensures rapid battery charging and consistent power output in demanding environments. The alternator's compact and lightweight construction, weighing approximately 16 pounds, allows for easy integration while maintaining durability and performance.

A key feature of the ARCO Zeus 24V 4kW is its use of a native 24V rotor and field current system, contrasting with competitors that rely on 12V field systems. This results in improved efficiency, lower operating temperatures, and an extended lifespan due to heat shedding coatings and dual cooling fans. The exterior rectifier housing and heat management technology contribute to cooler operation, especially during sustained high-output cycles. Built with OEM components and finished with an E-coat/Cerakote black coating, this alternator is designed for longevity and reliability.

The unit is optimized for cruising speeds and optimized to create additional power from your engine, reducing reliance on separate generators. Compatibility with the ARCO Bluetooth Alternator Regulator allows for maximum performance tuning and lithium battery charging. Certified SAE J1171 and proudly manufactured in the USA, this alternator offers a robust solution for demanding power needs. Its technical specifications include a maximum cold RPM output of 144 amps and a regulated operation up to 19,000 RPM, ensuring a wide range of performance in various applications. Mounting replaces Mando-type alternators using Vortec/GM pad feet, common on many marine engines, making installation straightforward and reliable.
