Product Description

Uav Accessories 3KW Drone Tether Supply Constant Voltage Output
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.
Main Applications of Drone Tethered Power System

-Day and night missions
-Radio relay
-Crisis management
-Site protection
-Traffic surveillance
-Large-scale events security
-Forest surveillance
-Industry monitoring
-Air-quality monitoring

2). Support takeoff weight: 10-15kg (drone power efficiency varies, this data is for reference only).
3). Supporting flight duration: ≥ 24h (the system can support working duration, which depends on the structure and electrical fatigue resistance of the drone).
3. Functional characteristics
1). Automatic reel in/out: Follow the takeoff and landing of the UAV to synchronously cable reel in/out, automated adjust the tension, and backup battery to activate cable reel in function in case of power cut off.
2). Communication function: Wired and wireless communication function, support remote display and control, client-side data viewing and downloading.
3). Protection function: Separate design for strong and weak electricity. Input and output voltage resistance≥3000VDC, tethered cable insulation voltage resistance≥3500VDC. Input overvoltage and undervoltage protection. Output overvoltage, overcurrent, short circuit, over temperature protection, fault elimination and self recovery. 
4). Data display function: The touch screen displays data such as output voltage, output current,output power, cable outlet length, working duration, installation temperature, total power consumption, fault record, and working status information.
5). Set adjustment: The display screen supports the setting and adjustment of wire winding speed, wire winding tension, wire reel out tension, safety length, date and time, and supports Chinese and English display.
6). Fault alarm function: When the system malfunctions, the display screen scrolls to display fault information, and beeps to alert.
7). Equipment carrying: With a backpack design, the backpack can be equipped with a complete set of tethering systems, including a tethering box, air module power supply, lighting unit (optional), and other accessories. The overall weight is 12 ± 0.5kg.
8). 5800W/7000Wh outdoor mobile power bank or 4300W/6.0L generator 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.
