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


• Monitors the state of charge


• Can turn your engine into a dedicated generator with generator mode


• Pre-set battery libraries


• Data logging and sharing


• CAN bus and NMEA 2000-integrated networks


• Compatible with all voltage systems (12- 48V)


• IP66 IP67 rated


• 2-Year warranty

The ARCO Zeus A275L Transit Alternator is engineered to deliver high output and high amperage, making it ideal for marine, RV, military, and commercial applications. Designed to replace noisy generators, this alternator quickly charges large battery banks while operating at cooler temperatures thanks to heat-shedding coatings, exterior-mounted rectifiers, and dual cooling fans. Its robust construction and OEM components ensure durability and reliable performance even under demanding conditions.
Built for optimal efficiency at idle speeds, the A275L enhances energy production without compromising engine performance. It features a large frame, a 16-pole rotor, and a 138mm stator, providing a maximum cold output of 311 amps at 9,000 RPM. The alternator's design includes a side-mount M8 threaded post and a standard 49mm multi-groove pulley, facilitating easy installation on various engine configurations. With a weight of approximately 15 pounds, it is suitable for replacing Ford Transit alternators on 3.5L and 3.7L gas engines from 2015 to 2022.
The Zeus high-energy alternator regulator distinguishes itself with Bluetooth connectivity and a native app compatible with iOS and Android devices. This allows for seamless installation, system monitoring, and configuration, giving users real-time insights into battery charge status and system health. The regulator can read two shunts simultaneously—battery and alternator—allowing precise control based on current and temperature data. It supports 12-48V systems, including lithium and lead-acid batteries, and offers pre-set libraries for optimized charging profiles.
Additional features include the ability to turn your engine into a dedicated generator with a simple toggle, data logging for troubleshooting, and compatibility with CAN bus and NMEA 2000 networks. The regulator comes with all necessary harnesses and thermistors, simplifying setup and saving time.
