Compatible with DJI M400 Tethered Drone System (Standard Edition)

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; backup power allows cable retraction even during power failure. Onboard power supply provides stable, regulated output voltage. Backup batteries exhibit no charging/discharging cycles or capacity loss. Compatible with UAVs. Supported flight altitude: ≥50/100 m (tether cable length: 55/110 m, with safety margin预留). Supported takeoff weight: 10–15 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; supports remote display and control, as well as client-side data viewing and downloading. Display: Real-time display of voltage, current, power, temperature, deployed cable length, operating duration, and power consumption. Configuration & Adjustment: Supports setting and adjustment of parameters such as tension, speed, and voltage; multilingual interface support. Alarms & Notifications: Fault conditions trigger on-screen alerts and loud audible buzzer notifications. Supports alarm activation via control panel buttons, mobile APP, and remote host computer. Automatic Cable Winding/Unwinding: Adaptive tension control; synchronized automatic cable deployment/retraction in coordination with UAV takeoff/landing; automatic orderly cable spooling. Transportation & Portability: Equipped with an aviation-grade carrying case capable of housing the complete system—including the onboard power unit.
