After being stepped down by the onboard power supply, it is converted into a DC stabilized output suitable for Drone Power Supply (such as 50V for 12S), providing a long endurance power supply mode for the drone.

　　Application areas of Tethered Drone

　　The application of Tethered Drone is very extensive, including but not limited to emergency rescue (emergency lighting, emergency communication, high-rise firefighting), military (intelligence surveillance, electro-optical reconnaissance, radar electronic warfare), public safety (relay self-organizing network, environmental monitoring), and civilian (nighttime power repair, high-rise building cleaning/spraying). These application scenarios require drones to remain in a fixed position for a long time to complete specific tasks.
