Product Description

Product Overview

Compact Tethered Drone Ground Power Station Air DC to DC Converter

Unlock the full potential of your drone with the Compact Ground Power Station. Featuring an efficient air DC-to-DC converter, it provides stable power and compact design for seamless tethered operations. Perfect for on-the-go missions!

Product Description

Typical characteristics

1). Easy to operate, no need to operate tethering box during UAV flight.

2). Comprehensive input and output protection function, fault elimination and self recovery.

3). Automatic take-up, and manual button to rewind when power cut off.

4). The on-board power supply has output at constant voltage, and the backup battery remains fully charged throughout the entire process without any power loss.

Adaptive drone

Support flight altitude: 200m/300m (tethered cable 220m/330m, reserved safety length).

Support takeoff weight: 60-90kg (drone power efficiency varies, this data is for reference only).

Support flight duration: ≥ 24h (the system can support working duration, which depends on the structure and electrical fatigue resistance of the drone).

Functional characteristics

1). Safety protection: Strong and weak current separation design, with input undervoltage, input overvoltage. Output overvoltage, output overcurrent, output short circuit, and output overheating protection functions. The input and output withstand voltage is ≥ 3000VDC, and the cable insulation layer withstand voltage is ≥ 3500VDC. 

2). Data communication: Wired and wireless communication functions, remote display and control, data viewing and downloading; fiber optic communication optional.

3). Data display: The touch screen displays data and status of output voltage, output current, output power, cable reel out length, operating time, equipment temperature, total power consumption, and fault records.

4). Setting and adjustment: Support the setting and adjustment of parameters such as tension and speed for reel in&out cable, date and time, output voltage, safety meters, alarm temperature, etc. and support Chinese and English.

5). Alarm and reminder: When a fault occurs, the screen displays the fault content, and the buzzer sounds a reminder.

6). Carrying and Transportation: The box is equipped with handles and foot pads, and can be optionally equipped with a pallet components and a pull rod roller for carrying and transportation.

7). Automated winch reel: Synchronously retracting and releasing cables following the takeoff and landing of the drone, automatic adjusting the tension, and backup battery to activate cable reel in function in case of power cut off.

8). Power supply 25000W/100L diesel generators is recommended.
