Product Description

Product Description

Long Time Hovering 12kw High Altitude Relay Communication Tether Drone Power System

      The New 12000W Drone Tether Power Supply System is an innovative solution designed to ensure continuous and stable operation of drones equipped with relay communication devices. This system provides a constant and reliable power supply to the drone through a tether, eliminating the need for frequent battery replacements and extending the drone's operational time significantly. With this system, drones can maintain a stable connection for relay communication, making it ideal for applications such as long - duration surveillance, data transmission, and remote monitoring.

Function characteristics

1). Safety protection: Strong and weak current separation design, with input undervoltage, input overvoltage. Output overvoltage, output overcurrent, output short circuit, and output overheating protection functions. The input and output withstand voltage is ≥ 3000VDC, and the cable insulation layer withstand voltage is ≥ 3500VDC. 

2). Data communication: Wired and wireless communication functions, remote display and control, data viewing and downloading; fiber optic communication optional.

3). Automated winch reel: Synchronously retracting and releasing cables following the takeoff and landing of the drone, automatic adjusting the tension, and backup battery to activate cable reel in function in case of power cut off.

4). Data display: The touch screen displays data and status of output voltage, output current, output power, cable reel out length, operating time, equipment temperature, total power consumption, and fault records.

5). Setting and adjustment: Support the setting and adjustment of parameters such as tension and speed for reel in&out cable, date and time, output voltage, safety meters, alarm temperature, etc. and support Chinese and English.

6). Alarm and reminder: When a fault occurs, the screen displays the fault content, and the buzzer sounds a reminder.
