3). The air module power supply has a constant voltage output, and the backup battery has no charging or discharging phenomenon throughout the entire process, without losing power or causing hidden damage.

Functional characteristics

1). Automatic reel in/out: Follow the takeoff and landing of the UAV to synchronously cable reel in/out, adaptively cable tension auto management, 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: Touch screen displays data such as voltage, current, temperature, cable outlet length, date, time, operation records, fault records, running time, total power consumption, and working status information.

5). Set adjustment: The display screen supports the setting and adjustment of wire winding speed, wire reel in tension, wire reel out tension, safety length, date and time, alarm temperature, and supports Chinese and English.

6). Fault alarm function: When the system malfunctions, the display screen scrolls to display fault information, and the buzzer strong sound reminder.

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.

Adapted to DJI M300/350

1). Support flight duration: ≥ 24 hours.

2). Support flight height: ≥ 50m/100m/150m (cable length has 55m, 110m and 160m).

3). Optional lighting: 640W or 1280W.

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.

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.
