IGNF-ST-400HZ Series Medium Frequency Static Variable Frequency Power Supply

IGNF-ST-400HZ Series Medium Frequency Static Variable Frequency Power Supply

Introduction:
The medium frequency static variable frequency power supply adopts IGBT soft switch, SPWM (silent pulse width modulation) inverter power supply technology, DSP microcomputer digital control technology and touch screen operation system. This medium frequency static power supply has stable output frequency, continuous and adjustable output voltage, and small waveform distortion. This variable frequency power supply has three phase independent separately adjusting and perfect communication interface functions. With good power panel human-computer interface and nice visibility, this medium frequency static power supply can automatically store and record the process curves of output current, voltage and frequency in time. The variable frequency power supply can be broadly used in military services like aviation, aerospace, weapon and ship, and in troop, airport, scientific research institute, national key labs where 400HZ medium frequency static invariable power supply is needed. This medium frequency static power supply can also be used in teaching experiments in universities.
