400Hz 90kVA 중주파 전원 공급 트럭

The 400 Hz intermediate frequency power supply produced by our company utilizes our proprietary patented technology and employs high-frequency power electronic switching conversion technology. It is a 400 Hz intermediate frequency static variable frequency power supply specifically designed and manufactured for aviation and military electronic and electrical equipment; it can be applied to aircraft and airborne systems, radar, navigation systems, and other military electronic devices, as well as any application requiring a 400 Hz intermediate frequency power supply. This product represents an upgraded generation of modular variable frequency power supplies. The voltage and frequency of this product offer a regulation range of ±20%, making it suitable for both balanced and any unbalanced three-phase loads, as well as for use as a single-phase power supply. It is compatible with various types of loads—such as resistive, capacitive, and inductive loads—as well as all types of hybrid loads.
