ALT29000001 is a high-performance aircraft alternator control unit (ACU), engineered to AS9100D aerospace quality standards and FAA TSO-C125 specifications, specifically designed for Boeing 737 MAX and Airbus A320neo narrow-body aircraft.

Constructed from rugged aerospace-grade thermoplastic with a metalized EMI shield, it operates in temperatures from -40°C to 85°C and withstands vibration levels up to 10g (10–2000 Hz), ensuring reliability in harsh flight conditions. This 2.1 kg unit regulates the output of 115V/400Hz three-phase alternators, maintaining a stable 28V DC power supply for avionics, lighting, and flight control systems. Featuring a built-in fault diagnostic module and CAN bus communication, it enables real-time monitoring by MRO teams, making it a critical component for preserving aircraft electrical system integrity and minimizing in-flight power disruptions.
