18000W Universal Tethered Power Supply System MTOW 82KG
1. Typical characteristics
1). Small size, light weight, easy to carry, and fast deployment.
2). Easy to operate, no need to operate tethering box during UAV flight.
3). Comprehensive input and output protection function, fault elimination and self recovery.
4). Automatic take-up, and manual button to rewind when power cut off.
5). The on-board power supply has output at constant voltage, and the backup battery remains fully charged throughout the entire process without any power loss.
2. Adaptive drone
1). Support flight altitude: 100/150m (tethered cable 110/160m, reserved safety length).
2). Support takeoff weight: 70-82kg (drone power efficiency varies, this data is for reference only).
3). Support flight duration: ≥ 48h (the system can support working duration, which depends on the structure and electrical fatigue resistance of the drone).
3. Functional characteristics
1). Cable retraction and release function: Follow the drone's takeoff and landing to synchronously retract and release the mooring cable, adaptively adjust the tension, and manual button to rewind when power cut off.
2). Communication function: It has wired communication function with serial port protocol and supports wireless communication function with Bluetooth or wireless serial port protocol.
3). Protection function: Input overvoltage and undervoltage protection, output overvoltage, overcurrent, short circuit, over temperature protection, fault elimination and self recovery.
4). 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.
5). Setting and adjustment function: The display screen supports the setting and adjustment of wire winding speed, wire winding tension, wire release tension, safety length, date and time, and supports switching between Chinese and English display.
6). 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.
