4402 - Arco Marine Zeus 24V 4kW Low Turn On Alternator w/Isolated Ground

Zeus 24V 4kW Low Turn On Alternator with Isolated Ground

The Zeus 24V 4kW Low Turn On alternator is designed to operate efficiently at lower RPMs, generating significant power while running cooler than traditional models. This alternator provides over 1.4kW (51 Amps) at nearly 1,500 RPM and up to 2.4kW (87 Amps) at 2,000 RPM. In practical terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio can yield over 1.5kW (55 Amps).

This innovative design exceeds older alternators, emphasizing durability and higher output. By employing a native 24V rotor and field current, the Zeus alternator outperforms competitors that utilize less efficient 12V configurations, leading to cooler operation and improved lifespan.

The ARCO Marine Zeus 24V 4kW Low Turn On Alternator with Isolated Ground (part number 4402) is engineered for applications requiring efficient power generation at lower engine RPMs. This alternator is designed to deliver over 1.4kW (51 Amps) at approximately 1,500 RPM and up to 2.4kW (87 Amps) at 2,000 RPM, making it suitable for rapidly charging large battery banks. Its native 24V rotor and field current contribute to cooler operation and an extended lifespan compared to less efficient 12V configurations. Key features include heat shedding coatings, an exterior rectifier, and dual cooling fans for thermal management. This unit is ideal for marine, RV, military, and commercial use cases where maximizing engine power for charging and reducing reliance on auxiliary generators is a priority. It is SAE J1171 Certified and made in the U.S.A.
