Ceaseless Power Supply for Drone/Unmanned Aerial Vehicle(UAV)
Main features
1) It has greatly extended the operation time of UAV, and supports continuous operation for 24 hours and uninterrupted immediate secondary operation;
2) It is small in size and light in weight. It can be carried by pull rod or hand. It can be used to tie down the folding cover of the box;
3) Automatic retraction and pay-off, the whole process of UAV takeoff and landing flight does not need to operate the tether box, just concentrate on the flight operation;
4) 640W or 1280W high-power and high-intensity lighting unit can be optional, and the effective lighting area can reach more than 10000 m2;
5) Comprehensive input and output protection function, operation, fault record and data storage, support wired communication and mobile phone synchronization;
6) The two modes of tether and release can be switched freely and quickly, which greatly expands the application scenarios and functions of the DJI M300 UAV.
