The AF-G4-100M tethered drone system can be combined with an airborne module to form a tethering system compatible with multiple drone platforms. This tethering system mainly includes: a winding reel, a tethering box, and integrated tethering cables and ground power supply. Its primary function is to provide wired power supply, information transmission, and cable winding/unwinding for the tethered drone. The winding reel mainly includes the system box, main frame, cable storage reel, and control circuit.

System box dimensions: 375mm x 345mm x 225mm (length x width x height)

System box dimensions including handle and control panel: 420mm x 345mm x 225mm (length x width x height)

Cable length: 100m

Weight: 13.5kg 0.5kg

External power supply: 220Vac

Maximum winding speed: 2m/second

Operating mode: Passive unwinding/Active winding

Output voltage: 400Vdc (30Vdc compensation)

AF-G4-100M UAV Tethered Power Supply Box

The AF-G4-100M UAV tethering case combines with an onboard module to form a complete tethered system compatible with multiple UAV platforms. The system includes a retractable winch, a tethering case, integrated tethering cables.delivering wired power, information transmission, and cable retraction for continuous drone operation.

Scenario: Compatible with various drone platforms, including DJI M200/M210, Inspire 2, M350, and drones that support 6S or 12S onboard module power supply and power consumption within 2500W

System Components:

• Retractable Winch: Includes system case, main frame, cable storage reel, and control circuitry.
• Integrated Tethering Cables: High-quality, durable cable for reliable power and data transmission.
• Ground Power Supply: Provides 400V DC (with 30V compensation) output to the drone.

Advantages of Tethered UAV Operation:

1. Extended Flight Time: Perform long-duration fixed-point missions without battery limits.
2. Enhanced Safety: Operate in no-fly zones, crowded areas, or hazardous environments with minimized risk.
3. Ease of Use: Simple operation requiring only basic flight skills.
4. High-Power Payload Support: Airborne module can provide high-power output for drones carrying heavier loads.

Key Features:

• All-aluminum alloy shell lightweight (<14kg) and durable.
• One-button start for high-voltage output and automatic cable retraction.
• No modification needed for the aircraft; just install the onboard module.
• Customizable shell color, text language, and fiber optic communication.
• Two transport modes available: backpack or trailer.

Usage Instructions:

Mooring Box Panel:

• Main power circuit breaker: controls all electrical devices.
• Main power switch button: energizes high-voltage DC output for the drone.
• Indicator light: shows power supply status.
• Torque adjustment knob: controls reel tension.
• Transparent panel: visual cable length observation.
• LCD Display: shows output voltage, current, power, and input voltage.

Wiring Instructions:

1. Connect the supplied power cord from mains or generator to the mooring box.
2. Connect the high-voltage cable (XT90) to the drones onboard power supply and secure the load-bearing hook.

Operating Instructions:

1. Adjust torque knob to minimum, close circuit breaker, and power on the system.
2. Pull cable out during takeoff; adjust torque for tension and reel-in synchronization.
3. Press “main power switch” to start high-voltage output when drone is ready to take off.
4. After mission, turn off main power, safely reel in the cable, and unplug power cord.

Maintenance & Safety:

• Level equipment before operation and wear insulating gloves.
• Adjust speed knob gradually; do not exceed max torque suddenly.
• Check cable, connectors, and moving parts every 50 flights or 20 hours.
• Store cables coiled in a dry, cool location; avoid dragging or sharp objects.
