Product Description

Multiple Protection Function 18KW MTOW 90KG Tether Drone Power System

      In today's rapidly developing technology field, tethered drones are undoubtedly a rising star. This innovative technology greatly extends the endurance of drones through tethering, enabling them to work continuously for over 24 hours, far exceeding the limitations of traditional drones that can only work for a few hours. This breakthrough not only significantly improves the efficiency of drones, but also brings revolutionary changes to multiple industries.
       The application fields of tethered drones are extremely extensive, from high-altitude monitoring to precision reconnaissance, from efficient cleaning to emergency firefighting, and even to critical relay communication, they can play an irreplaceable role. This versatility makes tethered drones an indispensable part of modern technology, providing stable and efficient services for both urban management and communication support in remote areas.

1. Typical characteristics 

1). Easy to operate, no need to operate tethering box during UAV flight.
 

2). Comprehensive input and output protection function, fault elimination and self recovery.
 

3). Automatic take-up, and manual button to rewind when power cut off.
 

4). The on-board power supply has output at constant voltage, and the backup battery remains fully charged throughout the entire process without any power loss.
 

2. Adaptive drone

1). Support flight altitude: 200m/300m (tethered cable 220m/330m, reserved safety length).
 

2). Support takeoff weight: 60-90kg (drone power efficiency varies, this data is for reference only).
 

3). Support flight duration: ≥ 48h (the system can support working duration, which depends on the structure and electrical fatigue resistance of the drone).
 

3.Functional 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). 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.
 

4). 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.
 

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

6). Carrying and Transportation: The box is equipped with handles and foot pads, and can be optionally equipped with a pallet components and a pull rod roller for carrying and transportation.

7). 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.
 

8). 25000W/100L diesel generators is recommended.
