Helios FU-B 3.6

Frequency converter in basic version without sine filter for speed control of a single fan. The speed setting is done via the 0-10 V control signal (e.g. potentiometer PU/PA, accessories). The maximum cable length between the frequency converter and the fan is 10 m with shielded cable. The fan must be designed for operation with a frequency converter (EMC-compliant fan/motor, possibly special version). The frequency converter is permanently set to its rated current. For operation with the frequency converter, the suitability for frequency converter use must be specified when ordering the fan.
