The 400Hz power supply is essential for powering aircraft and onboard equipment, serving as a necessary ground support facility for civil airports, aircraft maintenance bases, aircraft manufacturing plants, and research institutions.
The small power 400Hz intermediate frequency transformer previously used EI core can be replaced with a ring core. The core material thickness should be between 0.08-0.2mm, with a weight reduction of approximately 20%. If a 0.35mm material is used for the core, the flux density should be lower. Pay attention if the core material is 0.5mm short stock, as it may result in higher temperature rise.
The 400Hz power transformer must utilize amorphous alloy materials, as its operating frequency ranges approximately from 400Hz to 15KHz. Using a standard iron core would result in excessive heat generation, making it unsuitable for use.
The 400Hz frequency conversion power supply is a 115V, 400Hz medium-frequency power supply specifically designed and manufactured for aviation and electronic electrical equipment. It is suitable for aircraft and onboard equipment, radar, navigation, and other electronic devices, as well as any applications requiring a 400Hz medium-frequency power supply.
