GFC-90M - Unitron UFC-90M 90 kVA Ground Power Unit (GPU)

The Unitron UFC-90M is designed to power a wide range of aircraft requiring 400 Hz electrical input, including commercial, military, and business jets. Its 90 kVA capacity makes it suitable for larger aircraft systems that require sustained ground power for avionics, lighting, air conditioning, and preflight checks. Depending on load demand, it supports simultaneous use with both narrow-body and wide-body aircraft. This versatility makes the UFC-90M a key component in modern ramp operations.

Yes, the Unitron UFC-90M is CE marked, meeting European safety, health, and environmental protection requirements. This certification allows the unit to be operated in global markets that require CE compliance and demonstrates that it adheres to strict manufacturing standards and international safety protocols.

The UFC-90M is rated for outdoor use and built with an aluminum NEMA 3R weatherproof enclosure. This enclosure provides protection against rain, sleet, and airborne debris, making the unit suitable for year-round ramp operations. Internally, thermal and overvoltage protections ensure continued performance in harsh environmental conditions. The system is also protected against short circuits and overloads.

Yes. The UFC-90M requires adequate ventilation clearance to maintain safe operating temperatures. According to the manual, the unit should be positioned to allow unobstructed airflow through its intake and exhaust vents. Failing to maintain clearance can result in thermal overload and reduced performance, especially in hot weather or enclosed spaces like hangars.

Routine maintenance for the UFC-90M includes checking filters, inspecting connections, verifying voltage calibration, and cleaning debris from ventilation grills. Scheduled inspections should be performed monthly and after prolonged use. Preventative maintenance enhances system reliability and reduces the risk of downtime.

The unit includes an internal protection system against overvoltage, undervoltage, short circuits, and phase loss. These safeguards help protect sensitive aircraft electronics from electrical anomalies. Built-in diagnostics and alarms also alert users to any fault conditions in real time.

The UFC-90M comes equipped with digital displays that monitor system output, fault detection, and unit status. These diagnostics provide readouts for voltage, frequency, current, and system health. LED indicators and alarm buzzers are included for quick notification of abnormal conditions, reducing troubleshooting time and minimizing equipment downtime.

Yes, the UFC-90M is approved for use in both outdoor ramp operations and indoor hangar environments. When used indoors, proper ventilation and exhaust routing are essential. The unit’s low noise profile and clean electric power output make it suitable for enclosed aircraft servicing areas that prohibit combustion-based GPUs.

Key safety features include emergency stop controls, output contactor interlocks, and overtemperature shutdown. The unit is also equipped with ground fault detection and overload circuit breakers. These features help ensure safety and protect connected aircraft during ground servicing.
