Description
DJI M400 drone tethered system. it converts single-phase AC to high-voltage DC and transmits it to the onboard power module via a high-performance nickel-alloy power cable to provide continuous power to the aircraft. Paired with the DJI TB100C tether-specific battery, it enables up to approximately 12 hours of continuous operation while ensuring flight safety. The system also integrates an ultra-compact, high-power lighting module for night and low-light missions.
System Components
The DJI Matrice 400 RTK drone tethered power supply system consists of 3 major parts that work together to deliver long endurance and powerful lighting:
- Onboard power module: Receives power from the tether, regulates and converts it to supply the aircraft and lighting system.
- Integrated auto/manual winch: Combines the ground power source, high-performance power cable, and automatic cable reel, supporting both automatic and manual modes.
- Lighting system: High-power, compact optical module offering both spot and flood illumination options.
Key Features
- Based on DJI SDK,tethered data real-time transfer to DJI Pilot , real time monitoring tethered data , control and operate via DJI Pilot .
- Continuous power: Single-phase AC input converted to high-voltage DC on the ground, stably transmitted via a nickel-alloy tether to the onboard end.
- Extended endurance: With a backup battery strategy, supports up to about 12 hours of continuous flight missions.
- Cable management: Supports automatic payout and retrieval of up to 110 meters of cable with fast, smooth operation, reducing impacts and bending on the cable.
- Highly integrated and portable: All-in-one winch design supports backpack and hand-carry transport for efficient deployment and teardown.
- Safety and reliability: Power delivery and cable protection mechanisms work in tandem to reduce risks from power loss, bending, and external impacts.
- Powerful lighting: Built-in ultra-compact, high-power lighting system suitable for diverse operational scenarios.
Application Scenarios
- Long-duration aerial inspection and surveillance
- Nighttime emergency lighting and security deployment
- Disaster assessment, search and rescue, and command support
- Specialized operations and media aerial filming in low-light environments.
