The Tronair 1190400C28T3 / 1190400C128T3 towable diesel aircraft ground power units allows simultaneous use of 400 Hz (90 kVA) AC and 28.5 VDC.


  • Cummins QSB 4.5, 155 HP, 4 cylinder, Tier-3/EU Stage-3A engine operating at 2000 rpm
  • 28.5 VDC provides 600 amps continuous and 2000 amps maximum
  • 24 VDC battery system
  • Electronic governor system (via the engine ECM)
  • Intake manifold pre-heater for cold weather starting
  • Electronic controlled engine ensures maximum performance
  • Operates on diesel or jet fuel

Engine Protection

  • Low oil pressure shutdown
  • High coolant temperature shutdown
  • Low coolant level shutdown


  • Operating Temperature: -25º F to 125º F (-31º C to 52º C)
  • Relative Humidity: 10 to 95%, non-condensing
  • No altitude derating required up to 10,000 ft when running in normal operating range


  • 90 kVA, 72 kW, 3 phase, 4 wire, 115/200 AC V continuous rating
  • Meets or exceeds SAE ARP5015A and MIL-STD-704-F electrical power quality requirements
  • 30 ft DC output cable with AN2551 aircraft plug
  • 35 ft AC output cable with AN3430 aircraft plug
  • DC output current can be adjusted from 300 through 2000 amps by a Current Limiter switch
  • Industry leading three phase 25 KVA input power transformer and a Solid State 2000 amp Silicon Controlled Rectifier (SCR) powers the 28VDC
  • Voltage Regulation: ± 1% no load to full load
  • Voltage Adjustment: ± 15 volts
  • Line drop compensation ensures full power to the aircraft under heavy loads
  • Harmonic Distortion:
    Individual: <1% of the fundamental (RMS) voltage
    Total: <2% of the fundamental (RMS) voltage
  • Phase voltage balance not to exceed 1% on a 3-phase balanced load and does not exceed 4% with 33% unbalanced load
  • Frequency Regulation: ± 2 Hz steady state


  • All engine and alternator parameters and faults are controlled, monitored and displayed using an advance digital GenSet controller with option to connect to a web-based server allowing for real-time central monitoring through the internet
  • LED indicator lamps
  • DC Interface Printed Circuit Board (IPCB); monitors, controls, and protects all aspects of DC operation. The IPCB is connected to the Firing Board for the SCR pack; it is responsible for the current output of the rectifier

Generator Protection

  • Automatic voltage regulator tightly controls the voltage output to a ±0.5% accuracy of the voltage set point, response time is <4ms
  • When a fault is detected, the enhanced automatic voltage regulator (EAVR) will disconnect the output cable from the airplane
  • Voltage Disconnects Output:
    Over: between 124 to 126 volts in 1 second and 180 volts L-N in 50 ms
    Under: <104 L-N in 7 seconds
  • Frequency Disconnects Output:
    Over: >420 Hz in 5 seconds
    Under: <380 Hz in 7 seconds
  • Built in DC protection includes output over/under voltage, over current, input phase loss detection, missing phase, input over/under voltage, input circuit breaker 100 amps, transformer over temperature, SCR over temperature and a temperature controlled variable speed cooling fan

Generator Overload

  • >125% rated load for 5 minutes
  • >15% for 30 seconds
  • >200% for 10 seconds
  • >210% for 2 seconds
  • Individual outputs 325 amps, 5 minutes, 90 kVA


  • Heavy-duty steel chassis, low profile and fifth wheel steering for easy maneuverers in tight ramp spaces
  • Large, removable doors for easy access
  • 35-gallon rust free fuel tank provides 12+ hours of run time
  • Towbar latches in upright position, a hand brake ensures that the GPU will not roll when towbar latch is released
  • Forklift pockets
  • Tie down rings
  • Deep cable trays
  • Finish: Durable Powder Coat Tronair Blue

Additional Features: 1190400C128T3
