Three-phase frequency inverter 400V 5.5Kw (7.5CV) vectorial, RFI filter and integrated programming panel
The frequency converters allow the control and speed variation of standard three-phase motors
This model of frequency converter already has a built-in RFI filter suitable for the CE market, to avoid electromagnetic interference that could occur with other electronic components.
In the front panel, it incorporates all the necessary buttons for motor control and a potentiometer for speed regulation. It can also be controlled from push buttons and external potentiometer. The front keypad (control panel) is removable, i.e. it can be detached from the frequency converter, and by means of a cable (not included in the scope of supply) fixed on a keypad. The programming panel is included in the scope of delivery.
The frequency converter includes the PLC function (PLC), you can use the inputs and outputs of the frequency converter. Input and output extension cards are available.
