ER400W as a power source to develop aircraft quality 400hz Power. It is mostly used in aircraft production manufacturing, aviation R&D, military/civil hangar, maintenance plant, aerospace equipment, military airport tarmac and wells, aviation factories.
ER400W series is one of the most popular static frequency converter. ER400W is designed to change the power at 50Hz or 60Hz to aircraft quality power at 400Hz.
It 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.
