Product overview
The Kitefly XF-400S56-2K from Nanjing Airfly Electronic Technology Co., Ltd. is an onboard power conversion component for tethered-drone systems. It accepts 340~450V input and provides 42.5~56.25V output, with an output power rating of 2000w and an unregulated 8:1 conversion ratio. Peak efficiency is up to 98% at 380V input. Its physical configuration includes a heat spreader; dimensions with the heat spreader are 86.7x36.0x12.6mm (3.41 × 1.42 × 0.50 inches), defining the component’s integration envelope.
Control and communication features comprise remote on/off switching, startup with no load and PMbus communication. Input protection includes undervoltage lockout and overvoltage protection, while output protection covers overvoltage, overcurrent and overtemperature. Reinforced isolation is rated at 4242Vdc from the input to the output/heat spreader. UL 60950-1 and UL 62368-1 approvals are pending. The manufacturing facility is certified to ISO 9001, TL 9000, ISO 14001, QS 9000 and OHSAS18001, with these certifications applying to the facility.
