The TLD GPU-409-E-CUP Aircraft Ground Power Unit features an optimized 1,846 RPM brushless revolving field generator, which efficiently produces 90 kVA (72 kW) 400 Hz AC power to start and service aircraft. Designed with operators in mind, the GPU-409 Ground Power Unit’s full-size performance comes in a compact size, allowing for easier handling and better mobility near aircraft while reduced sound levels ensure customer and passenger comfort. Powder-coated aluminum and fiberglass panels that surround a rugged galvanized steel chassis are a durable, yet lightweight alternative to traditional designs. Mobility is enhanced by a rubber torsion axle, tight turn radius fifth-wheel steering, simple direct-acting brakes and a safe nodrop towbar. The unit’s engine can meet U.S. Tier 4i and EURO emission standards. Other engines options are available that will meet the specific regulatory needs of your geographic location.

The GPU-409-E-CUP is available with an optional 28.5 volts DC power output package, part number GPU-409-E-CUP-28. The 28V option creates dual outputs for a 90 kVA 400 Hz AC and 28 VDC combination aircraft ground power supply.

Generator Controls:

Digital generator control module (GCM) features voltage regulation, generator fault protection, and a generator operating parameter display. The GCM monitors the 400 Hz output when 400 Hz is in use and automatically switches over to monitor 28.5 VDC output when optional 28.5 VDC transformer rectifier is in use. The voltage regulator provides line drop compensation on 400 Hz as well as line drop compensation and current limiting on optional 28.5 VDC transformer rectifier. The GCM displays the generator output operating parameters such as voltage, current, and frequency digitally on a backlit LCD. The GCM is programmed to provide generator output fault protection in the following settings:

  • Over frequency: 420 Hz in 5 seconds
  • Under frequency: 380 Hz in 7 seconds
  • Over voltage: 130 volts in 2 seconds
  • Under voltage: 100 volts in 7 seconds
  • Overload: 125% of rated load for 5 minutes

Engine Controls:

Electronic engine governors provide precise frequency regulation and fast transient response. Engine protection such as low oil pressure and high coolant temperature are programmed into the ECM. An engine diagnostic connector is provided for communicating with the engine. Engine operating parameters are displayed via SAE J1939 CANBUS:

  • Engine speed, voltage and hours
  • Oil pressure and coolant temperature
