Customers who can not place an order please contact us;
The AF-G7 portable automatic retraction and deployment system for tethered drones primarily consists of a retraction winch, a tethering case, integrated tethering cables. This system provides wired power, information transmission, and cable retraction for the tethered drone. The retraction winch includes a system case, a main frame, a cable storage reel, and control circuitry.

3. Instructions for use
1. Description of the mooring box panel:
(1) Main power circuit breaker: the main switch for all electrical components, including the mooring box control power supply and the mooring power main power supply;
(2) Main power switch button: the switch button for the aircraft power supply. When pressed, the system high-voltage DC is energized and outputs 400V DC high voltage to supply power to the drone onboard power supply;
(3) Main power switch indicator (integrated on the main power switch button ring light): used to indicate the mooring box power supply status;
(4) Torque adjustment knob: used to control the reeling torque;
(5) Transparent panel: used to visually observe the winch cable length status.
(6) LCD display information:
Output voltage: displays the current ground power output DC voltage value
Output current: displays the current ground power output DC current value
Output power: displays the current ground power output power value
Input voltage: displays the current ground power input DC voltage value
2. Wiring Instructions
(1) Connect the power cord provided with the assembly from the mains or generator to the tethering box. Plug one end of the cord directly into the tethering box socket, and the other end directly into the mains or generator.
(2) The high-voltage cable output of the tethering box is an XT90 connector. Connect the cable to the drone's onboard power supply, as shown below.
Fix the load-bearing hook (the load-bearing hook pulls the wire to bear the force).
3. Operation Instructions
(1) During operation, first adjust the torque adjustment knob to the lowest position, then close the circuit breaker, and the system will be powered on. The display on the panel will light up.
(2) When the drone is ready to take off, adjust the torque knob to the lowest position or add a little torque (in windy conditions), and pull the cable out through the drone. When reeling in the cable, adjust the torque knob from small to large to synchronize with the drone's descent speed.
You can also adjust the torque to the appropriate torque from the start, always keeping the cable at a certain tension. The drone will release the cable and force the cable to hover. When landing, the cable will automatically reel in due to a certain tension.
(3) When the drone needs to be powered, press the "main power switch" button. The cooling fan of the tethered box will start working, and the "main power operation" indicator light will be on. The display will show the current output voltage, current output current and output power of the main power cable. When the system is loaded with current, the indicator light will turn on and the aircraft will be powered.
It is recommended that the main power be turned on when the aircraft takes off 5m or the propellers start rotating. The aircraft will descend to 5m off the ground. When the main power is turned off, it will prevent the inevitable reverse electromotive force shock to the airborne module. (4) After the task is completed, turn off the main power switch first, and the high-voltage DC power supply will be cut off. When performing the remaining cable reeling operation, prevent accidental electric shock. Finally, turn off the main power switch and unplug the power cord. 4. Precautions 1) Before starting to use, please try to level the equipment and keep it in a relatively balanced state; 2) Operators should wear insulating gloves to prevent accidental electric shock; 3) When adjusting the speed knob, turn it slowly from small to large, and do not adjust it to the maximum suddenly; 4) After retracting, wrap the power cord and place it in the box. Do not drag it on the ground; 5) The mooring cable should not be dragged on the ground during use to avoid linting. Pay attention to whether there are stones or other sharp objects on the ground to avoid cutting the cable. 5 6 IV. Product maintenance and warranty after-sales 1. Storage and transportation When transporting the mooring power box, it must be treated with shock absorption. Otherwise, it is normal for the internal screws to loosen. 2. Maintenance (1) Check and maintain the tethered power supply every 50 takeoffs and landings or 20 hours of flight to ensure the normal operation of the tethered power supply. (2) Check whether the various components of the tethered power supply have been subjected to strong impact and check whether the movable parts of the tethered power supply are still running smoothly. Inspection: 1) Cable inspection: Carefully check the entire length of the tethered cable to see if there is any damage to the outer sheath, exposed armor layer, excessive bending, or bent/contaminated connector pins. This is the most important step. 2) Interface cleaning: Disconnect all electrical connectors, check and clean the dust and moisture in the interface, and ensure that it is dry and clean. 3) Light body and module cleaning: Use a dry soft cloth to wipe the lighting body and power module housing to ensure that the ventilation holes are not blocked. 4) Standard storage: Store the cables neatly in a coiled manner, avoid small radius bends, and store in a cool and dry place.
