UFC-90M-UDC620 - Unitron UFC-90M-28VDC Dual-Output AC & DC GPU – 90 kVA (AC) & 28V DC – 3-Phase Input Voltage

The Unitron UFC-90M-28VDC is designed to support a wide range of commercial, military, and business aircraft that require both 400Hz AC power and 28VDC output. Its dual-output capability makes it suitable for mixed fleets and maintenance environments where different aircraft power requirements are common. This versatility helps reduce the need for multiple ground power units on the ramp or in the hangar.

Yes, the UFC-90M-28VDC is engineered to deliver simultaneous 400Hz AC and 28V DC outputs from a single ground power unit. This allows technicians to power avionics and perform engine start operations without switching equipment. Total output remains limited to the unit’s rated capacity to ensure safe and reliable operation.

The UFC-90M-28VDC is built for indoor and outdoor operation, making it suitable for both hangar maintenance and ramp environments. Its rugged enclosure and environmental protection help it withstand temperature extremes, moisture, and debris commonly encountered during ground operations. This flexibility supports year-round use across varied operating conditions.

The integrated self-diagnostic system continuously monitors system performance and records fault data in an onboard event log. This allows technicians to quickly identify issues, reduce troubleshooting time, and minimize aircraft downtime. Diagnostic visibility also helps maintenance teams plan service more efficiently and proactively address potential problems.

The unit includes multiple safety protections, such as overload, short-circuit, over- and under-voltage protection, and emergency power-off capability. Automatic line monitoring and safety interlock options further enhance protection for both aircraft and ground personnel. These safeguards are especially important during engine start and high-load operations.

Automatic line-drop compensation helps maintain a stable output voltage by compensating for voltage loss along long cable runs. This ensures consistent power delivery even when the GPU is positioned farther from the aircraft. Stable voltage improves avionics protection and reduces the risk of power-related faults during servicing.

The UFC-90M-28VDC supports multiple communication interfaces, including USB, Ethernet, RS-232, and RS-485. These connections allow for system monitoring, data logging, and integration with maintenance networks. Network connectivity helps operators track usage, diagnostics, and service history more efficiently.

By combining AC and DC power in a single unit, the UFC-90M-28VDC can replace two separate ground power units. This reduces equipment acquisition costs, simplifies maintenance, and frees up valuable ramp space. Fewer units also mean less congestion around the aircraft during ground operations.

Yes, the unit is designed to meet or exceed multiple aviation and electrical standards, including UL certification and international power specifications. It is also manufactured in an ISO 9001:2015-certified facility, supporting consistent build quality and reliability. Compliance helps ensure acceptance across global aviation operations.

The UFC-90M-28VDC can be configured with optional input and output cable lengths, aircraft safety interlocks, and alternate mounting configurations. These options allow the unit to be tailored to specific operational needs and facility layouts. Customization helps ensure efficient deployment in both fixed and mobile ground power setups.
