Three-phase frequency converter 400V 5.5kW (7.5CV) vector, with built-in RFI filter and fixed (non-removable) programming panel. The three-phase frequency converters (frequency inverters) allow the control and speed variation of standard three-phase motors from a three-phase supply network. They are only suitable for connection to AC motors.

This model of frequency converter incorporates RFI filter to avoid electromagnetic interference that could occur with other electronic components. On its front panel, it incorporates all the necessary controls for motor control and a potentiometer for speed regulation. This inverter model can be controlled from potentiometer and external push buttons.


The VFC3 series of frequency converters incorporates:

  • Integrated programming panel (not removable) with adjustment dial
  • 15 programmable speeds with input activation
  • PID control
  • RS485 communication
  • RFI filter included
  • DIN rail mounting as standard
