Product Description

Product Description

The Latest 12kw Tether Drone Power Supply System for Live TV Aerial Photography

      The tethered power supply system is perfectly adapted to the heavy load UAV with MTOW 40~60Kg, which is ready to use without any modification, and the product includes two parts: the tethered box (ground module) and airborne power supply (air module). This product convert the tethered box of the ground module into a high voltage 750V transmitted to the airborne power supply of the air module by mains or generator , and then the airborne power supply is converted into the working voltage of the UAV, which continues to supply power for the UVA to achieve the long-term hovering fixed point operation. The long-term experiment results show that under the working condition of using this product, the UAV can reach 24 hours or more non-stop fixed-point hovering operation.

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.
