Rosefinch Tether Power Station

Specialized in providing tether power station system for DJI drones. Rosefinch Technology is a joint venture company which was formed jointly by RescueTech and ZhongNeng. It is located in the Baixia High tech Industrial Park in Qinhuai District, Nanjing. It mainly engages in the R&D, production, sales of AC-DC, DC-DC high-frequency switching power modular, the drone tether power system and the lighting system. There products has the characteristics of smaller size, lighter weight, simple operation, reliability and stability, and powerful functions, cable auto reel in&out along with drone up/down, air module constant voltage output. It breaks the homogenization of market products and providing the industry with more user-friendly, practical, and cost-effective tethered UAV products. In 2005, we cooperated in participating in the demonstration of a large load tethered UAV project in the Army and began the research and development of high-power tether power stations. It successively developed military grade tether power systems such as air module output power 25kW/15kW. In 2020, participated in multiple military and civilian tethered UAV projects. In the same year, multiple standard series products covering flight altitudes of 55-330 meters and takeoff weights of 5-60 kg were successively launched, and mass production and sales were achieved. In 2022, began the R&D of industry tethered power systems suitable for DJI drones and YUNEEC drones. At the end of the year, launched the tether power systems for matrice 300 and Yuneec H850. In the first half of 2023, it successively launched tether power stations for M30, M3, Yunnec H520, and other models. We have always adhered to independent research and development of core technologies. The air module adopts a output voltage stabilizing circuit scheme, with a wide range of input and constant voltage output, which is different from the commonly used Vicor power supply unstable voltage scheme on the arket.
