The FYXL-XP01 tethered power supply system can be adapted to multi-UAV platforms, inclucing DJI M200/M210, Inspire 2, M300, as well as UAVs that support 6S or 12S power supply within 2500W. Just replace and use the airborne module that adapts to different UAVs. The system consists of an airborne module and a ground integrated power supply box. The electrical energy is transmitted from the ground to the airborne module on the drone through the high-performance alloy power supply line, and converted into the DC 6S/12S voltage used by the drone, which can continuously power the drone. It can be directly connected to generators or 220V mains power, allowing drones to perform ultra-long endurance operations on a safe basis. At the same time, the airborne terminal module provides a 48V/24V power interface (automatically switching between battery and power supply), which can be used by other airborne devices, such as mounting floodlights to realize emergency lighting at night, mounting relays to restore communication or extend communication distance, mount the camera gimbal to achieve long-term monitoring, etc.
