The Tronair 1128261E0CH is a high-output 28.5V DC solid-state aircraft rectifier ground power unit built for aviation maintenance environments where elevated continuous or peak current delivery is required. Operating on 60Hz 3-phase input voltage, this single-output unit is part of Tronair's next-generation 1128 rectifier series and delivers clean, regulated DC power with voltage ripple held below 0.2V DC RMS. A stable external 28V DC supply is essential for ground servicing of aircraft whose onboard systems cannot be powered from utility AC directly, and the 1128261E0CH is engineered to meet that demand at a higher output capacity than the standard configuration.

The higher current capability of the 1128261E0CH makes it well suited for operations involving engine start support, large-cabin business jet servicing, or sites where multiple high-draw loads must be supported from a single GPU. By powering onboard avionics, flight management systems, and electrical equipment from the ground unit rather than the aircraft's batteries, technicians can complete system checks, software loads, and preflight inspections without engine run-up or battery drain.
The 1128261E0CH meets MIL-STD-704F power quality standards and is NEC compliant. It includes a 15A, 115V AC GFCI duplex weatherproof receptacle, an energy-efficient thermal-control cooling fan for operation under 52 dB, and comprehensive overvoltage, overcurrent, and short-circuit protection. The towable low-profile steel frame with pneumatic wheels and a steering handle makes hangar and ramp positioning straightforward for a single technician. CE rated and backed by Tronair's 2-year Platinum warranty.
