Description
400Hz power transformers are used in various energy conversion power supplies. They are crucial to aerospace and military industry for aircraft systems as the lightweight solution to the traditional 50/60Hz heavy electronics. The application is not limited to flight systems, but also in stationary controls, airport equipment, and vehicle mobility systems. This larger class of 400Hz power transformers has an operating temperature range from -55°C to +130°C.
