Engineered for professional-grade tethered drone operations, the DJI M400 Tethered Drone System redefines reliability with three core advantages: its sleek, refined aesthetic design enhances on-site integration, seamlessly blending with diverse operational environments; IP-rated waterproof functionality ensures uncompromised performance in damp, rainy, or high-humidity conditions; and universal multi-scenario compatibility enables seamless adaptation to outdoor operations, large-scale events, and complex industrial environments alike. Marrying form and function, it meets the rigorous demands of professional missions.

• (1) Flight Altitude Support: ≥ 100 meters (equipped with an 110-meter professional-grade tethered cable, including 10 meters of redundant length for enhanced safety and operational flexibility).
• (2) Extended Flight Duration: ≥ 24 hours of continuous operation (note: actual endurance may vary based on the drone’s structural integrity and electrical system durability).
• (3) Optional Lighting Upgrade: 800W high-power lighting module (available as an add-on for low-light or nighttime missions, expanding operational versatility).

Adopting a lightweight design, it is compact in size, lighter in weight, and can be easily carried by one person. It supports rapid deployment in the field and meets the needs of mobile missions.

Electrical isolation: design with complete separation of AC high voltage and DC low voltage electricity.

Equipped with multiple protection mechanisms such as input overvoltage/undervoltage, output overcurrent/short circuit, etc., automatic fault detection and recovery ensure stable system operation.

Ultra High Voltage Withstand Standard ≥ 3000VDC.

Adopting low-voltage soft starting mode, replacing traditional circuit breaker starting, with ultra-high waterproof rating far superior than air switches, further improving the safety of isolated AC contact use.

Real time display: electrical parameters such as real time

power/voltage/current/temperature/cable length/power consumption/running time.

Operating data curve chart: Voltage/current/temperature curve chart. Fault record. Logs storage and read.

The onboard module provides constant voltage output, that avoids ineffective charging and discharging losses, protect battery lifespan, and always maintain a fully charged standby state during operation.

Automatically follow the takeoff and landing of the drone to retract cables.

Fully automated operation process, unmanned aerial vehicle takeoff and landing do not require manual operation throughout the entire process, reducing operational barriers and improving task efficiency.

Built in backup power supply, it can automatically switch to backup power mode in case of sudden power outage, completing emergency wire retraction and avoiding the risk of cable entanglement.

Wired communication between GCS and ground power module: USB Type-C or RJ45 high-speed transmission.

Wireless communication between GCS and ground power module: Bluetooth 5.0 low-power connection.

Optic fiber wireless communication between GCS and drone: Optic fiber. Achieve fast data transmission.
