Portable Tether Power Station for Unmanned Aerial Vehicle(UAV)/Drone
Product overview
The main function of this product is to provide safe and reliable long-endurance flight power for DJI M300UAV up to 24 hours.
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.
