Product Description

Dji Flycart 30 Tether Power System with fiber optic Support Data communication

Tethered drones are unmanned aerial systems connected to ground power sources via cables, possessing prolonged hovering capabilities. These drones can conduct extended flight missions within designated areas without concerns over energy depletion, thereby enabling long-duration aerial surveillance, communication relay, and data collection operations. Such systems are particularly suitable for disaster emergency response, border patrols, security at large-scale events, and environmental monitoring, providing critical aerial support during pivotal moments.

Typical characteristics 
1). Easy to operate, no need to operate during UAV flight.
2). Comprehensive input and output protection function, fault elimination and self recovery.
Fully automatic cable reel in/out function, and backup battery to activate cable reel in function in case of power cut off.
3). The air module power supply has a constant voltage output, and the backup battery has no charging or discharging or power loss phenomena.
4). The air module power supply is in stead of a original drone battery without any structural changes to the drone.

Adaptive drone

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.

Rosefinch Technology is the leading manufacturer of drone tethering power station.
Rosefinch mainly engages in the R&D, production, sales of AC-DC, DC-DC high-frequency switching power modular and the drone tether power system.The system is compatible for all multi rotor drones with MTOW 3-110kg.

These products are used and deployed by armed forces, law enforcement, civil security, and private security in over 20 countries for event protection, perimeter surveillance, border protection, radio communications, long-duration health monitoring, emergency communication, traffic management, environment inspections, scientific research and many more.

We have always adhered to independent research and development of core technologies. The air module adopts a output voltage stabilizing circuit scheme, with a wide range of input and constant voltage output, which is different from the commonly used Vicor power supply unstable voltage scheme on the market. It can ensure that the backup battery in parallel with it has no charging or discharging phenomenon, no battery capacity loss, and is only used as backup battery for landing, achieving true long-term tethering flight without battery capacity loss; The automatic cable reel in & out control adopts a difference between the reel out tension and reel in tension, and an adaptive torque transformation scheme, chieving true automatic tether cable reel in & out function without human intervention.
