Product Description

Product Description

Dji Matrice 350 300 Rtk Tethered Drone Power System for Building Window Cleaning with Automatic Retractable Tether Cable

      The tether power supply system can perfectly adapt to the DJI Matrice 300RTK and Matrice 350RTK drones, providing uninterrupted, long-endurance power for demanding aerial operations. Designed specifically for building washing and window cleaning, this system eliminates battery limitations, enabling continuous flight for hours without the need for frequent landings or swaps.

      Equipped with stable voltage output and intelligent power management, the tethered solution ensures safe and reliable performance even in high-intensity tasks. The rugged ground power station delivers consistent energy through a high-strength tether cable, allowing the M300/M350 RTK drones to operate at peak efficiency for extended missions.

Function characteristics

1). Automatic reel in/out: 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.

2). Communication function: Wired and wireless communication function, support remote display and control, client-side data viewing and downloading.

3). Protection function: Separate design for strong and weak electricity. Input and output voltage resistance≥3000VDC, tethered cable insulation voltage resistance≥3500VDC. Input overvoltage and undervoltage protection. Output overvoltage, overcurrent, short circuit, over temperature protection, fault elimination and self recovery.

4). Data display function: Touch screen displays data such as voltage, current, temperature, cable outlet length, date, time, operation records, fault records, running time, total power consumption, and working status information. 

5). Set adjustment: The display screen supports the setting and adjustment of wire winding speed, wire reel in tension, wire reel out tension, safety length, date and time, alarm temperature, and supports Chinese and English. 

6). Equipment carrying: With a backpack design, the backpack can be equipped with a complete set of tethering systems, including a tethering box, air module power supply, lighting unit (optional), and other accessories. The overall weight is 12 ± 0.5kg.

 7). 5800W/7000Wh outdoor mobile power bank or 4300W/6.0L generator is recommended.
