Function characteristics

Adapted to D JI Matrice 400

1). Support flight altitude: ≥ 100m (equipped with 110m professional tethered cable, including 10m redundant length).
2). Support flight duration: ≥ 24 hours (actual endurance is affected by the structural strength and electrical system durability of the drone).
3). Optional lighting: 800W.

1. Lightweight and Portable, Fast deployment
Compact design, easy to carry by one person, supports rapid field deployment for mobile operations.

2. Intelligent Winch Automated Control System
Follow the takeoff and landing of the UAV to synchronously cable reel in/out, adaptively cable tension auto management, and
backup battery to activate cable reel in function in case of power cut off.

3.  Smart Power & Battery Management
Constant voltage output prevents unnecessary charging/discharging, extending battery lifespan and always maintain a fully charged standby state during operation.

4. Real-Time Monitoring Touchscreen (4.3-inch)
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.

5. Multiple Protections, Safe and Reliable

 •  Complete AC/DC isolation for maximum safety 

 •  Multiple protections: overvoltage, undervoltage, overcurrent, short circuit  •  Ultra-high withstand voltage ≥ 3000VDC

6. Flexible Communication System
Wired communication: USB Type-C or RJ45 high-speed transmission.
Wireless communication: Bluetooth 5.0 low-power connection.
Optic fiber wired communication: Optic fiber. Achieve fast data transmission.

7. Low Voltage Button to Start AC Input, No Need AC Air Switches, Improve The Safety. 
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.
