Single-phase frequency converter 230V 0.4Kw (0.5CV), 230V three-phase output, RFI filter and integrated programming panel.

Frequency converters (frequency inverters) monophasic allow the control and speed variation of standard three-phase motors to run from a single-phase supply network. They are only valid to be connected to AC motors.

This model of frequency converter already has a built-in RFI filter to avoid the electromagnetic interference that could occur with other electronic components.

In the front keypad, it incorporates all the necessary buttons for motor control and a potentiometer for speed regulation. It can also be controlled by pushbutton and external potentiometer.

The series of frequency converters L of the firm DELTA incorporates:

  • Potentiometer.
  • 3 Programmable speeds with activation by inputs.
  • RS485 communication.
  • Integrated RFI filter.
  • Programming panel integrated in the front (not remotelizable).
  • Does not include braking module.
