Tronair 1128161E0CH - 28.5V DC Rectifier, 60Hz

The Tronair 1128161E0CH is a next-generation 28.5V DC solid-state aircraft rectifier and ground power unit designed for FBO, MRO, and flight line operations requiring reliable, clean DC ground power. Operating on 60Hz 3-phase input voltage, this single-output unit is the direct successor to the legacy 112860S series, delivering regulated 28.5V DC power with ultra-low voltage ripple of less than 0.2V DC RMS. Many systems aboard general aviation and corporate aircraft require a stable 28V DC external supply for ground servicing, and because this voltage cannot be drawn directly from utility power, solid-state rectifiers like the 1128161E0CH convert 3-phase AC input into the clean, regulated DC output that aircraft systems demand.

By supplying stable, regulated power directly to the aircraft, the 1128161E0CH allows technicians to perform avionics testing, software updates, lighting system checks, and other electrical maintenance without running the engines or drawing down onboard batteries. This reduces engine wear, extends battery service life, and accelerates preflight readiness across the maintenance workflow.

The 1128161E0CH meets MIL-STD-704F power quality standards and is NEC compliant. It includes a 15A, 115V AC GFCI duplex weatherproof receptacle for convenient shop power access, an energy-efficient thermal-control cooling fan for quiet operation under 52 dB, and built-in overvoltage, overcurrent, and short-circuit protection to safeguard both the unit and the aircraft's electrical system. The towable low-profile steel frame with pneumatic wheels and a steering handle allows easy positioning across hangar floors and outdoor ramps. CE rated and backed by Tronair's 2-year Platinum warranty.
