Powerful Tethered Power Station for Unmanned Aerial Vehicle/Drones
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.
Adaptive UAV
It is matched with corresponding UAVs to form a tethered drone system.
1) Support flight height: 120~200m (cable length: 220m, reserved safety length);
2) Support takeoff weight: 30~55kg (UAV force efficiency is different, this data is for reference only).
Environmental characteristics
1) Ambient temperature: - 20~45 ºC (working), - 40~65 ºC (storage);
2) Relative humidity: 10~80% RH (working), 5~90% RH (storage); 3) Altitude: 0~3000m.
