Product overview
The Kitefly WF-1000S60-4K from Nanjing Airfly Electronic Technology Co., Ltd. is an onboard power supply for drone integration. It converts an 800–1000Vdc input, rated at 900Vdc, to a regulated 60 ±0.6Vdc output with a range of 57–60.6Vdc. Rated output power is 4000W, with 67A rated current and a 75A maximum. Ground supply compatibility calls for at least 4000W output at 800–1000Vdc, with consultation for system matching. The product is a power module for integration into a drone.
The module weighs 1000g and uses an aluminum enclosure with three-proof PCB coating and certified IP54 protection. Heat sink dimensions are 187 × 95 × 70mm, providing the dimensional reference for integration space. Operation from -40°C to +50°C requires forced air cooling; storage temperature is -40°C to +80°C, and maximum altitude is 2000m. Parallel operation is limited to eight units. Efficiency is ≥97% at 750Vdc input and half load, while dynamic response recovery is ≤2ms for a 25%–50%–25% load step.
