Power Control Unit (PCU) Fault Analyzer

Power Control Unit (PCU) Fault Analyzer-The Ultimate Field Test Tool for Aircraft Power System Maintenance

When your aircraft’s power system fails, every minute counts. Our PCU Fault Analyzer is the portable, rugged solution designed to get your fleet back in the air faster. Engineered specifically for aircraft power management centers, it turns complex fault data into actionable insights in minutes—no guesswork, no delays.

Technical Specifications

Applications

This PCU Fault Analyzer is a professional-grade maintenance tool designed for aircraft operators, MRO (Maintenance, Repair & Overhaul) facilities, and military aviation units. It is ideal for:

• Field Maintenance: Quickly diagnosing and troubleshooting faults in aircraft AC/DC power systems, generator control units (GCU), and ground power supply systems at airfields or remote sites.
• Hangar Testing: Performing detailed offline analysis of PCU fault records to identify potential system risks before they cause downtime.
• Routine Inspections: Regularly monitoring the status of aircraft power management centers to ensure compliance with safety standards and extend system lifespan.
• Troubleshooting Support: Providing maintenance teams with actionable fault data to reduce aircraft turnaround time and improve fleet operational efficiency.

Functionality

The analyzer delivers comprehensive diagnostic and protection capabilities to streamline aircraft power system maintenance:

• Power Supply & Protection: Supplies dual redundant, isolated power to the PCU, with automatic overcurrent/overvoltage protection and manual power control for safe operation.
• Fault Code Decoding: Reads and parses fault codes from both A and B channels of the PCU, reconstructing the exact time, type, and operational context of each failure.
• Real-Time Monitoring: Tracks contactor status, command signals, AC BTB control signals, and PCU fault states in real time for proactive maintenance.
• Automated Testing & Reporting: Runs built-in self-tests and generates Excel-format diagnostic reports, enabling fast data sharing and repair decision-making.
• Safety Control: Features a two-level power safety system (manual + program-controlled switching) and anti-misplug test lines to prevent operational errors.

Key Features

• Rugged Portability: Weighing ≤ 10kg and housed in a durable transit case, it is engineered for reliable performance in harsh environments (-20°C to 55°C operating temperature).
• User-Friendly Interface: An intuitive, easy-to-navigate human-machine interface allows technicians to quickly query and trace historical test records without specialized training.
• Dual Power Input: Supports AC220V ± 10% / 50Hz or DC28V ± 10% for flexible use in both workshop and field settings.
• Enhanced Safety: Dual redundant power supply and overcurrent/overvoltage protection safeguard both the analyzer and the aircraft’s PCU during testing.
• Efficient Reporting: Automatically generates clear, structured test reports to reduce paperwork and accelerate maintenance workflows.
