Product Description

Large Emergency Tether Drone Power System with Constant Voltage Output for Surveillance
 

Typical characteristics 

Easy to operate, no need to operate during UAV flight.
 

Comprehensive protection function, capable of self recovery.
 

Fully automatic cable reel in/out function, allowing manual retract in case of power loss.
 

The air module power supply has a constant voltage output, and the backup battery has no charging or discharging or power loss phenomena.

 

Adaptive drone

Support flight duration	≥ 24h
Support flight altitude	≥200/300m, (tethered cable 200/300m, reserved safety length)
Optional task payloads	floodlights, spotlights, tweeters, aerial suspension systems, communication base stations

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, client data viewing and downloading; optional fiber optic communication.
 

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 the retraction and release of cable, date and time, output voltage, safety meters, alarm temperature, etc. and support switching between 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.Automatic cable retraction and release: synchronously retracting and releasing cables following the takeoff and landing of the drone, adaptively adjusting the tension, and manually retracting cables under power loss conditions.

8.Optional task payloads include aerial suspension systems, pan tilt cameras, floodlights, spotlights, flash warning lights, and speakers.
