Product Description

How to build a tethered drone with a stable 3KW 50V output tether ground power station

1. Typical characteristics
1). Small size, light weight, easy to carry, and fast deployment.
2). Easy to operate, no need to operate tethering box during UAV flight.
3). Comprehensive protection function, fault elimination and self recovery.
4). Airborne power supply constant voltage output, the backup battery has no capacity and voltage loss.

2. Adaptive drone
1). Support flight altitude: 100m, reserved safety length.
2). Support takeoff weight: 10-15kg (drone power efficiency varies, this data is for reference only).
3). Support flight duration: ≥ 48h (the system can support working duration, which depends on the structure and electrical fatigue resistance of the drone).
 

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.

4. Air module (onboard power supply)

5. Tether cable

6. Ground module (tethering box)
