Low-power single-phase 400 Hz intermediate frequency power supply

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, other military electronic equipment, as well as any application requiring a 400 Hz intermediate frequency power supply, representing a next-generation replacement for fixed-type variable frequency power supplies. This product features a voltage and frequency adjustment range of ±20%, making it suitable for both balanced three-phase and arbitrary unbalanced loads, as well as for use as a single-phase power supply. It is compatible with various types of loads—including resistive, capacitive, inductive loads—as well as various hybrid load configurations.
