ARCO Zeus 24V 4kW Low Turn-On (LTO) Alternator with Isolated Ground and Zeus High-Energy Regulator

Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground (Common Rail) Zeus High-Energy Alternator Regulator

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 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 alternators lifespan.

Zeus High-Energy Alternator Regulator

ARCOs Zeus is the only high-energy external alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you can access information on your system that you never had before. This information will enable you to regulate your system and optimize your battery charge and alternator output, resulting in a safer experience while protecting your energy system investment.

Zeus is the only alternator regulator that can read 2 shunts at a time (the battery shunt and alternator shunt). This feature enables Zeus to react to inputs from the battery current/temperature and alternator current/temperature.

Through the ARCO Zeus application, you are in good hands. Your data is automatically logged and can be shared with your technician to troubleshoot your system remotely. You can even import your remote technicians configurations.

Zeus optimizes battery charges for 12-48 volt systems. Whether you are using Lithium (LiFePo4) batteries or lead-acid Deep Cycle batteries, Zeus has you covered with its pre-set battery libraries and configurable menus to optimize your charging profiles. Zeus manages a complex set of inputs by giving you easy-to-understand options.

Zeus also takes into consideration the power of your engine and allows you to configure the alternators power take-off from the engine by managing the field, or duty. An advanced feature of Zeus is that it can turn your engine into a dedicated generator with the press of a button, whereby it focuses the alternators performance on the creation of energy to replenish your battery bank quickly.

Consistent with Zeus ease of use, Zeus is the only alternator regulator on the market that comes with alternator/battery harnesses and 2 thermistor harnesses, without an additional charge, saving users money and time from sourcing harnesses.

Features:

• Secure Bluetooth connection


• Harnesses, Thermistors, and NMEA 2000 kit included

The ARCO 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. Its design allows it to generate over 1.4kW (51 Amps) at just under 1,500 RPM and nearly 2.4kW (87 Amps) at 2,000 RPM. For practical context, a marine diesel engine idling at 750 RPM can produce over 1.5kW, and a Mercedes Sprinter at the same RPM with a 3.21:1 pulley ratio can produce over 2.5kW, illustrating its robust power output. The alternator's efficient operation results from its native 24V rotor and field current, which run cooler and extend lifespan compared to competitors utilizing 12V rotors. This design also reduces heat, contributing to increased durability and sustained performance. Featuring heat-shedding coatings, exterior-mounted rectifiers, and dual cooling fans, the ARCO Zeus alternator ensures optimal operating temperatures, even during prolonged use. Its large frame and lightweight construction make installation straightforward while maintaining durability and high energy output. The alternator is compatible with engines introduced after 2013 on Yanmar Common Rail systems, such as JH-CR, 3JH40, 4JH45, 4JH57, 4JH80, and 4JH110 models. Technical features include a maximum RPM of 19,000, a cut-in RPM of 1,072, and a maximum output of 3,960 watts at cold start conditions. The unit also features a M8 threaded side post for easy wiring, standard 6-groove pulleys, and avalanche-rated diodes for safety and longevity. The Zeus alternator regulator complements this power source with Bluetooth connectivity, allowing remote configuration via IOS and Android apps. It monitors system charge states, manages multiple shunt inputs, and can turn your engine into a dedicated generator, optimizing energy production. The regulator's pre-set battery libraries support lithium and lead-acid batteries, ensuring efficient charging profiles. Included in the package are harnesses, thermistors, and a NMEA 2000 kit, making setup quick and cost-effective.
