Tronair 1128162E0CK - 28.5V DC Rectifier, Dual Output

The Tronair 1128162E0CK is a dual-output 28.5V DC solid-state aircraft rectifier and ground power unit designed for FBO and MRO operations that need to power two aircraft or two independent aircraft systems simultaneously from a single unit. Operating on 60Hz 3-phase input voltage, this next-generation 1128 series rectifier provides two output cables with standard aircraft DC connectors, each delivering clean, regulated 28.5V DC power with voltage ripple below 0.2V DC RMS. For operations where servicing throughput matters, the dual-output configuration eliminates the need for a second GPU, reducing equipment footprint and cost on the flight line.

Standard Features

• Front Panel Usage History Summary
• Emergency Power "OFF" Switch
• Integrated Communication Ports
• Input High Voltage Protection
• Adjustable Output Current Limit from 150 amps to full rated current (150A-2000A)

Each of the two outputs delivers stable power suitable for avionics testing, software loading, lighting checks, and ground system verification without drawing on the aircraft's onboard batteries or requiring engine operation. The dual outputs can support two independent aircraft concurrently or be used to feed separate electrical systems on a single aircraft, giving ground crews added flexibility in how they structure their maintenance workflow.

The 1128162E0CK 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 built-in overvoltage, overcurrent, and short-circuit protection on each output. The towable low-profile steel frame with pneumatic wheels and a steering handle allows easy single-operator positioning on both hangar floors and outdoor ramps. CE rated and backed by Tronair's 2-year Platinum warranty.
