Tronair 1128262E0CK - 28.5V Dual Output GPU, 60Hz

The Tronair 1128262E0CK is Tronair's high-output dual-cable 28.5V DC solid-state aircraft rectifier GPU, engineered for demanding ramp and hangar environments where high current capacity and dual aircraft connectivity are required together. Operating on 60Hz 3-phase input voltage, this next-generation 1128 series unit provides two output cables delivering simultaneous 28.5V DC power with voltage ripple below 0.2V DC RMS and full MIL-STD-704F compliance. As the highest-capacity configuration in the 60Hz dual-output 1128 lineup, the 1128262E0CK is built for high-throughput flight lines, engine start operations, and large-cabin jet servicing environments where standard-capacity units may not meet peak demand.

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)
• Voltage & Current Monitoring
• 18" Frame legs
• Elapsed Time Meter
• Meets NEC 18" Rule, Article 513 NEC

Both output cables provide clean, regulated DC power suitable for avionics system testing, flight management software updates, lighting verification, and full electrical ground checks without running the aircraft engines or depleting onboard batteries. The combination of high peak current and dual connectivity makes this unit a productive choice for busy maintenance bays where two aircraft may require ground power simultaneously.

The 1128262E0CK 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 quiet operation under 52 dB, and comprehensive overvoltage, overcurrent, and short-circuit protection on both output channels. The towable low-profile steel frame with pneumatic wheels and a steering handle supports easy single-operator positioning in hangar and ramp environments. CE rated and backed by Tronair's 2-year Platinum warranty.
