Continuous Power Supply Cable Auto Reel Tether Power System
The main function of this product is to provide safe and reliable long-endurance flight power for DJI M300 UAV up to 24 hours.
This product can be used as a tool to enable users to concentrate on flight operations without additional operations during the whole takeoff and landing flight operations.
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.
