Compatible with DJI M400 Tethered Drone System (High-End Version)

Typical Features Compact size and lightweight for easy portability. Simple operation: the entire UAV takeoff and landing process requires no manual intervention with the tethering box. Comprehensive input/output protection functions enable automatic fault recovery. Fully automated cable winding/unwinding functionality allows cable retrieval using backup power in case of power failure. Onboard power supply provides stable, regulated output voltage; backup batteries exhibit no charging/discharging or capacity loss issues and are compatible with UAVs. Supported flight altitude: ≥100/200 m (tether cable length: 110/220 m, with safety margin reserved). Supported takeoff weight: 5–10 kg (UAV thrust efficiency varies; this data is for reference only). Supported flight duration: ≥24 hours (system capability; actual duration depends on aircraft electrical components and structural fatigue resistance). Functional Features Safety Protection: Separation of high- and low-voltage circuits; comprehensive overvoltage, overcurrent, short-circuit, and overtemperature protection for all inputs and outputs. Data Communication: Wired, Bluetooth, and digital transmission capabilities support remote display and control, as well as client-side data viewing and downloading. Data Display: Displays voltage, current, power, temperature, deployed cable length, operational duration, and power consumption. Configuration & Adjustment: Supports setting and adjustment of parameters such as tension, speed, and voltage; multi-language interface selection available. Alarms & Notifications: Fault conditions trigger on-screen fault messages and loud audible alerts via buzzer; notifications supported via control panel buttons, mobile app, and remote host computer. Automatic Cable Winding/Unwinding: Automatically adapts tension and synchronizes cable winding/unwinding with UAV takeoff and landing; ensures neat cable layering. Transportation & Portability: Equipment housed in an aviation-grade case capable of accommodating the complete system, including the onboard power supply.
