Product Description

Customizable VTOL Drone Unlimited flight time tether power system for tethered drone

 
The main function of this product is to provide safe and reliable long-endurance flight power for drones.

This product includes two parts: the ground end tether box and the sky end airborne power supply. The tether box integrates AC/DC DC power supply, automatic take-up and pay-off device, tether cable and intelligent control module to convert single-phase AC power of the mains, generator or mobile power supply into high-voltage power and transmit it to the airborne power supply through the tether cable. The airborne power supply can safely replace an original battery and provide constant voltage stabilization, continuous and reliable long-endurance power supply for the UAV without reducing the standard load weight. The system has the function of automatically retracting and releasing the line synchronously following the rise and fall of the UAV.

This product can be used as a tool to enable users to concentrate on flight operations without additional operations during the whole takeoff and landing flight operations.



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.

 

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.

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.

Yes, support take off weight 60-90KG.

2). What happens if the ground power is cut?
The backup drone battery will kick in and supply power to the drone. At battery critical level, the drone will auto land.
The the ground power recover power to drone, then it automated switch to tether power to drone. 

3). Will there be warranty? How long?
Yes there will be warranty for 1 year.
Extend warranty is optional.
