Arco Starting & Charging AZADM Zeus Omega Alternator Drive Module

The Arco Starting & Charging AZADM Zeus Omega Alternator Drive Module (ADM) is the alternator-side component of ARCO's patent-pending Zeus Omega Alternator Control System. Designed for marine, RV, and powersports applications, the ADM mounts directly at the alternator and communicates with the Zeus Omega Control Module via a single AZ CAN communication cable — eliminating the complex multi-wire harnesses required by traditional alternator regulators.

Key Features:

• Alternator-Mounted Design: Installs directly at the alternator using short pigtails — three quick-connect fittings plus positive and ground ring terminals when paired with an ARCO alternator
• IP68 Fully Sealed Enclosure: Rated for the harshest engine compartment environments, including moisture, heat, and vibration
• Single-Cable Communication: Connects to the Zeus Omega Control Module via one AZ CAN cable using industry-standard N2K-style DeviceNet connectors — no proprietary wiring required
• Scalable Architecture: One Zeus Omega Control Module supports up to six ADMs, enabling multi-alternator charging systems
• Hall Effect Current Sensing Compatible: Supports direct alternator current sensing via ARCO's Hall Effect sensors (sold separately, Part No. AZHSADM), replacing traditional analog shunts for faster installation and more accurate diagnostics
• Emergency Charging Mode: If communication with the Control Module is interrupted, the ADM automatically reverts to independent float-voltage charging, keeping critical systems protected
• Belt-Loss Detection: Detects when the alternator stops turning and shuts off charging to protect the rotor and charging system components
• Multi-Voltage Support: Compatible with 12V, 24V, 36V, and 48V charging systems
• USA Assembled: PCBAs manufactured in-house at ARCO Marine's Pensacola, Florida facility with proprietary firmware
• 2-Year Warranty: Covered under ARCO's standard two-year limited warranty

The AZADM is a standalone replacement or expansion ADM for the Zeus Omega system. It is compatible with both internal and external regulator-type alternators, selectable via the ARCO Zeus app. Whether expanding an existing Zeus Omega installation or replacing a component, the AZADM delivers intelligent alternator regulation with a dramatically simplified installation process.
