FLYTEK GPU – 28 VDC GPU
FlyTek 28 VDC GPUs (Ground Power Units) provide continuous output power for a wide range of aircraft. Through innovative research and development, FlyTek 28 VDC GPUs provide continuous DC power to both military and civilian aircraft that are on the ground to start the engine, the APU (Auxiliary Power Unit) of the aircraft, as well as for the onboard power supply. The units are available in mobile or fixed configurations, suitable for either hangar or ramp use.
Input
- State of the art semiconductor technology (IGBT) Rectifier
- Power Factor Correction (PF= 1)
- 95% efficiency
- 4 Quadrant Operation (better response of the system and safer operation for NBPT)
- Low input harmonics (<1.5% THDi), to comply with the strictest regulations @ any load
Output
- Voltage compensation (Load Dependent or via Remote Feedback – Real PLUG & PLAY. Connect GPU to aircraft and voltage compensation is done automatically, no user adjustment required or additional accessories)
- 4 Quadrant Operation (better response of the system and safer operation for NBPT)
- Vector control Inverter for better response and higher efficiency.
