Portable Drone Tether System DJI Mavic 3 : Empowering Endless Aerial Operations
In drone technology, the DJI Mavic 3 Tethered Power System is a notable innovation. Designed for security, surveying, and environmental monitoring, it can revolutionize these fields. By using ground - based power, it overcomes the short flight - time problem of traditional drones.Equipped with this system, the Mavic 3 can fly continuously for over 8 hours, much longer than battery - only drones. This extended flight time not only lengthens missions but also ensures power stability, crucial for accurate data in long - term surveys. In high - risk security or tough - terrain monitoring, the system enables stable, long - term drone use, expanding drone applications and enhancing their professional performance.
The Applications of Tethered Drone
The tethered UAV can be applied in situations and environments that require long-time operation, making up for the shortcomings of short endurance time, faster power consumption with more mounts, and the need for frequent battery replacement. It expands the industry application of UAV.
Typical characteristics
- It is small in size and light in weight, with a tethered box weighing only 3.6kg. It is easy to carry with a backpack for storage.
- . Replace the primary battery, without changing any structure of the UAV, and seamlessly switch between tethering mode or flying mode.
- . The operation is simple, and the entire process of drone takeoff and landing does not require the operation of the ground module. The button type take-up function is also available.
- . The onboard power supply has a constant voltage output,and the backup battery has no charging or discharging phenomenon throughout the entire process, without losing power or causing hidden damage.
