MYUAV High Voltage Power Supply For Tethered Drones / Uav

Product overview
This product includes two parts: the ground end tether box and the sky end airborne power supply. The tether box integrates AC/DC DC power supply, automatic take-up and pay-off device, tether cable and intelligent control module to convert single-phase AC power of the mains, generator or mobile power supply into high-voltage power and transmit it to the airborne power supply through the tether cable. The airborne power supply can safely replace an original battery and provide constant voltage stabilization, continuous and reliable long-endurance power supply for the UAV without reducing the standard load weight. The system has the function of automatically retracting and releasing the line synchronously following the rise and fall of the UAV.

FAQ

1. **Q: What is MYUAV's tethered power station? **.
**A:** MYUAV's tethered power station is an innovative high-altitude power generation solution that uses tethered drone technology to connect a large drone to a ground power source. The drone carries a small wind turbine or solar panel to fly high into the sky, using high-altitude wind or sunlight resources to generate electricity, and then sends the power back to the ground via tethered cables.

2. **Q: How does MYUAV tethered power station work? **.
**A:** The working principle is mainly to use the drone as a platform to lift it to the height that the traditional wind turbine cannot reach, where the wind speed is more stable and strong, thereby improving the power generation efficiency. The UAV receives a constant supply of electricity through high-strength cables attached to the ground to maintain the flight of the UAV and the operation of the power generation equipment.

3. **Q: How efficient is the MYUAV tethered power station? **.
**A:** Because the actual data depends on the specific UAV model and the configuration of the power generation equipment, MYUAV may have increased the power generation per unit area through the efficient use of wind or solar resources. Compared to traditional ground-based power plants, high-altitude wind or solar power has a higher power generation potential per unit area, but the exact efficiency figures need to refer to the product performance indicators provided by MYUAV company.

4. **Q: In what environment can MYUAV tethered power stations operate? **.
**A:** MYUAV's tethered power stations should be able to operate within a safe range of meteorological conditions, such as avoiding extreme weather conditions, while ensuring the safety and stability of tethered cables. The specific operating environment conditions should be consulted with MYUAV for detailed standards prior to purchase.

5. **Q: How to recover and maintain tethered UAVs? **.
**A:** MYUAV may be equipped with an automated or semi-automated recovery system to safely land and recover the teemed UAV if necessary, while performing regular maintenance checks on the power generation equipment on the UAV. The maintenance process may include integrity inspection and repair of the drone body, power system, power generation equipment and tethered cables.

Again, the above information is based on the general application of tethered UAV technology. For more details about MYUAV's tethered power station products, please contact the company directly for the latest and most accurate product descriptions, performance parameters and service support.
