High Power High Voltage High Energy DJI Matrice 300 Tether Drone Power System
With the continuous advancement of technology, the performance and application range of tethered drones will continue to expand, indicating that future drone technology will become more intelligent and efficient. For enterprises and individuals pursuing technological innovation and efficiency improvement, tethering drones is undoubtedly a direction worth paying attention to and investing in.
1. Typical characteristics
| 1). Small in size, light weight, backpack storage, easy to carry, with a tethered box weighing only 8.5kg. |
| 2). Air module power supply 980g< single TB60 battery 1350g, safe replacement and non-destructive mounting. |
| 3). Replace a battery without changing any structure of the drone, and seamlessly switch between tethering mode or free flight mode. |
| 4). The operation is simple, and the entire process of unmanned aerial vehicle takeoff and landing does not require the operation of the mooring box, truly automatically reel in/out. |
| 5). The air module power supply has a constant voltage output, and the backup battery has no charging or discharging phenomenon throughout the entire process, without losing power or causing hidden damage. |
2. Adapted to DJI M300/350

3. Functional characteristics
Automatic reel in/out: Follow the takeoff and landing of the UAV to synchronously cable reel in/out, adaptively adjust the tension, and manually press the button to retract the cable while power cut off.
|
Communication function: It has wired communication function with serial port protocol and supports wireless communication function with Bluetooth or wireless serial port protocol.
|
Protection function: Input overvoltage and undervoltage protection, output overvoltage, overcurrent, short circuit, over temperature protection, fault elimination and self recovery.
|
Data display function: The 4.0 inch touch screen displays data such as voltage, current, temperature, cable outlet length, date, time, operation records, fault records, and working status information.
|
Set adjustment: The display screen supports the setting and adjustment of wire winding speed, wire winding tension, wire reel out tension, safety length, date and time, and supports switching between Chinese and English display.
|
Fault alarm function: When the system malfunctions, the display screen scrolls to display fault information, and the fault alarm light flashes red and beeps to alert.
|
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.
