Product Description

Uninterruptable Power System Dji M300/350 Support  Live TV aerial photography

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.

1. Typical characteristics
1). Small size, light weight. It is easy to carry. Rapid deployment.
2). Simple operations, the entire process of drone taking off and landing does not require the operation of ground module.
3). Comprehensive input /output protection,fault elimination and self recover. 
4). Fully automatic take up and pay off function, the wire can be rewound once ground power cut off.
5). The air module power supply has a constant voltage output, and the back up battery has no charging and discharging phenomenon.

2. 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.
3. Functional characteristics 

1). Protection function: Separate design for strong and weak electricity. Input over-voltage, input under-voltage. Output over voltage ,output over current, output circuit, output over temperature protection, input and output voltage resistance≥3000VDC, tethered cable insulation voltage esistance≥3500VDC.
2). Data communication: Wired and wireless communication function. Support remote display and control, client-side data viewing and downloading.Optional fiber optic communication.
3). 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.
4). Set and adjustment: The display screen supports setting and adjustment the parameters such as reel in/out tension and speed, date and time, output voltage, safety lengths, warning temperature, etc., and support Chinese and English.
5). Alerts and reminds: When the system malfunctions, the display screen scrolls to display fault information, and the buzzer strong sound reminder.
6). Automatic take-up and payoff: Following take off and landing of the drone to synchronously tethered cable automated winch reel in/out, adjusting the tension auto management, and backup battery to activate cable reel in function in case of power cut off.
7). Carry and transport: The ground module is equipped with a handle and foot pads. folding trailer and trolley wheels is optional for transportation.
8). Power supply 5800W/7000Wh outdoor mobile power bank or 4300W/6L gasoline inverter 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, achieving true automatic tether cable reel in & out function without human intervention.
