Product description

The VFVN 100 F frequency converter provides better control of fans in buildings with automatic control. It combines the basic functions of the VFVN 100 frequency converter with special functions designed specifically for airflow control processes. The frequency converter is available in several frame sizes, with the enclosure meeting IP21/UL Type 1 or IP54/UL Type 12. The power range extends from 0.55 kW up to 630 kW and the devices can be powered from 230 to 500 V. For 690 V supply, the range is from 5.5 kW to 800 kW.
