The applications of Tethered Drone
The tethered UAV can be applied in situations and environments that require long-time operation, making up for the shortcomings of short endurance time, faster power consumption with more mounts, and the need for frequent battery replacement. It expands the industry application of UAV.




Company Information
 

The "Drone Tethered Power System" - 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.
Our Mission:
Provide best quality, fastest service and most professional tether solution for drone users. 
Our Vision: 
Be the leading manufacturer of drone tether station. 
 

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.
