    ER-PS-400W Solid-State GPU 400Hz Frequency Converter

    Our 400hz frequency converter is the most reliable solutions on the market today. It is used in all types of aircraft under the harshest environmental conditions. Our products have quality assurance, free replacement within one year, if you are interested, please contact us.

    Introduction of 400hz Frequency Converter:

    ER-PS-400W Solid-State GPU 400Hz Frequency Converter, as the power source for the development of aircraft quality 400Hz power supplies, it is mainly used in aircraft production manufacturing, aviation R&D, military/civil hangar, maintenance plants, aerospace equipment, military airport tarmac and wells, aviation factories.

    ER-PS-400W series is one of the most popular static frequency converters. ER-PS-400W is designed to change the power at 50Hz or 60Hz to aircraft quality power at 400Hz.

    400hz frequency converter integrates IGBT made by Mitsubishi, Siemens and Infineon with PWM switching technology, and combines micro controller and digital signal processor (DSP) for quicker response and higher reliability.
