STATIC FREQUENCY CONVERTER
Serial Code: 123456
Frequency Converters are designed to provide high quality and reliable voltage and frequency conversion for military applications.
The use of high frequency pulse modulation (Pulse Width Modulation - PWM) ensures excellent performance and very low noise.
Correction techniques and special input circuits in the rectifier section guarantee lower input currents and reduced harmonic distortion.
The electric supplied power is 25KVA / 20KW.
