G35‑M400 Tethered Power Station is a tethered power system designed specifically for the DJI Matrice 400 drone. It consists of a ground‑based tether box and an airborne power supply. Using 850V high‑voltage transmission, the tether cable is thinner and lighter with lower wind resistance, reducing the load on the drone’s propulsion system. The new AI‑driven speed and torque control system supports cable retraction/extraction speeds up to 5 m/s, delivering truly hands‑free, contact‑free automatic cable management – no cable sag, oscillation, severe swinging, or sudden jerking. Multi‑end connectivity is supported via the device panel, mobile app, PC, and drone remote controller.
The Matrice 400 tethered drone can carry mission payloads such as gimbal cameras, floodlights, searchlights, loudspeakers, optical‑display devices, cleaning spray guns, etc., enabling long‑endurance aerial video shooting, area surveillance, high‑power illumination, searchlight scanning, voice broadcasting, warning announcements, light‑show projection, curtain‑wall cleaning, and more.
