Bonfiglioli Active frequency converters

Bonfiglioli Active Series

The range includes models of frequency converters that are characterized by versatility and easy to use.

The series is characterized by high management performance, scalability and small device dimensions. The main advantage of this line is the possibility of field control with or without a sensor. The principle of operation of frequency converters is to change a three-phase or single-phase alternating current of 50 Hz to a three-phase or single-phase current, but with a selected frequency. Depending on the model, this can be from 1 Hz to 800 Hz. On our website, you can find models of electric induction type.

For a smooth start of speed control, the ED-use an electronic frequency Converter that works like an inverter-passes current through itself and creates a voltage at the output with the necessary frequency. Vector control is implemented in the most advanced devices.

The principle of this control is to constantly maintain the specified speed level on the ED shaft. This type of control is suitable if you do not care about the exact relationship between the speed of rotation and the moment (when the load changes at the same frequency). When the voltage is reduced, vector frequency converters also reduce the load, while minimizing the reactive current.
