The VFC 500 Series is a variable AC power source designed to deliver power at a selectable frequency between 40Hz to
440Hz. The unit uses PWM technology and generates a sine-wave output with typical distortion of less than 5%. The
output voltage is continuously adjustable from 0 to full scale. The input is power factor corrected.
The VFC 500 Series AC power source can be used as a compact AC/AC frequency converter, suitable for a wide range of
applications. It features full electronic protection, high efficiency and low output noise. The unit is fan cooled. The use
of components with established reliability results in a high demonstrated MTBF. The VFC 500 is manufactured at our
plant under strict quality control. Customized versions are also available.
