ARCO Marine Zeus 24V 4kW Low Turn-On Alternator with Isolated Ground and Single Foot Mount

Zeus 24V 4kW Low Turn On (LTO) 1-2 Single Foot 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 onthe alternator lifespan.

The ARCO Marine Zeus 24V 4kW Low Turn-On (LTO) alternator is engineered to deliver high performance at lower RPMs, making it ideal for marine, RV, military, and commercial applications. Featuring a native 24V rotor and field current, this alternator operates cooler and more efficiently than competitors that rely on 12V rotors, which enhances longevity and reliability. Its robust design enables it to generate over 1.4kW (51 Amps) at just under 1,500 RPM and nearly 2.4kW (87 Amps) at 2,000 RPM, providing substantial power for large battery banks and demanding environments. This means that even idling engines, such as a marine diesel at 750 RPM with a 2:1 pulley ratio or a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio, can produce significant charging power, reducing engine load and enhancing efficiency. The Zeus alternator's advanced cooling system, including dual fans and heat shedding coatings, ensures optimal operating temperatures, extending its service life and maintaining peak performance under continuous use. The external rectifier and exterior-mounted diodes facilitate easier maintenance and improved heat dissipation. Built with OEM components and finished with durable E-coating, the ARCO Zeus is designed for demanding environments and long-term reliability. Its compatibility with Bluetooth regulators allows for customizable performance tuning and lithium battery charging, making it a versatile choice for various power systems. The alternator features a large frame size, side-mount M8 post, and a standard 49mm multi-groove pulley, ensuring straightforward installation onto most engine configurations.
