Product Overview

The main function of the tethered power system is to provide safe and reliable long-term flight power for unmanned aerial vehicles, consisting of a tethered box and an onboard power supply. The tethered box includes a retractable winch, ground power supply, and tethered cables. The tether box is placed on the ground to convert AC power provided by the generator or mains power into high-voltage DC power, which is transmitted to the onboard power supply through tethered cables. The onboard power supply is installed on the drone and converts high-voltage DC power into low-voltage DC power for use by the drone. The tethered cable follows the drone's ascent and descent and automatically synchronizes the retrieval and release, transmitting electrical energy and signals.

This product is mainly paired with multi rotor unmanned aerial vehicles to provide stable and reliable power supply. It not only solves the problem of short battery life on board, but also solves the drawbacks of the widely used unstable tethered power supply scheme. It can truly achieve continuous long endurance hovering flight operations of unmanned aerial vehicles. Unmanned aerial vehicles can achieve different application scenarios by mounting different mission payloads, and can transfer location targets with all movable devices such as people, vehicles, ships, etc. They are mainly used in high-altitude lighting, video surveillance, emergency rescue and disaster relief, and emergency communication fields.

Main features

1. The system only retains the input switch, high-voltage switch, and strong retraction button, with simple operation and control, and can be quickly deployed. After takeoff and before landing, the drone can be operated without human intervention. Users only need to operate the drone, which can greatly improve work efficiency and safety;
2. Product integration, high power density, high reliability design, miniaturization, lightweight, modular and intelligent design, easy to move and carry, troubleshooting and maintenance, greatly ensuring the relevant requirements for use in various environments and occasions;
3. The control system has powerful data processing functions, communication functions, synchronous clock and memory storage functions, comprehensive protection and alarm functions, automatic program recognition, intelligent control, and intelligent troubleshooting and self recovery functions.
