ARCO Marine Zeus 24V 4kW Low Turn On (LTO) J180 Alternator with Isolated Ground

Zeus 24V 4kW Low Turn On (LTO) J180 4 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) J180 Alternator is designed to deliver superior power output at lower RPMs, making it ideal for a variety of marine, RV, military, and commercial applications. Featuring a native 24V rotor and field current, this alternator operates cooler and more efficiently than traditional models that utilize a 12V rotor, significantly extending its lifespan. It can continuously generate over 1.4kW (51 Amps) at just under 1,500 RPM and nearly 2.4kW (87 Amps) at 2,000 RPM, providing reliable power even during idling conditions. For example, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio can produce over 1.5kW, while a Mercedes Sprinter at the same RPM with a 3.21:1 ratio can generate more than 2.5kW, demonstrating its robust performance in real-world scenarios. The design emphasizes durability and high energy production, making it suitable for charging large battery banks and supporting demanding power needs. The alternator features heat shedding coatings, dual cooling fans, and an external rectifier located on the housing exterior, ensuring optimal operating temperatures and enhanced performance. Its black E-coating finish provides additional protection against harsh environments. The unit is engineered with OEM components and includes a 49K6 pulley, M8 side mount post, and avalanche-rated diodes, ensuring high quality and reliability. Certified to SAE J1171 standards and proudly made in the USA, the ARCO Zeus 24V 4kW alternator is a high-performance solution for demanding power applications. It is compatible with most Volvo Penta alternators using a 4 J180 saddle-style mount, simplifying installation and integration into existing systems. With advanced cooling features and efficient operation, this alternator is engineered to maximize performance and longevity, making it a valuable asset for any power generation setup. Use with the ARCO Zeus Bluetooth Alternator Regulator for maximum performance or lithium battery charging, ensuring your power system operates at peak efficiency.
