Product overview
The Kitefly D4 from Nanjing Airfly Electronic Technology Co., Ltd. is a ground power supply for tethered drone installations, with the equipment designation AF-D4. Its physical package measures 420 × 200 × 95 mm and weighs 6.2 kg ±0.3 kg, defining the space and mass required for ground-side integration. The configuration incorporates a cable retraction system capable of real-time automatic operation and includes a manual winding handle for manual cable winding.
Electrical integration centers on ground-adjustable power from 0–4000 W and an adjustable 0–500 V DC output, supplemented by auxiliary outputs of 24 V / 130 W and 5 V / 1 A. Real-time compensation maintains stable voltage at the onboard terminal. The display supports output-voltage and power recording together with temperature acquisition. Operating limits are -20 °C to +60 °C, with use at 5000 m altitude specified. Fiber optics can be added as an additional configuration.
