Helios FU-B 5.0

Frequency inverter in basic version without sinus 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 inverter and the fan is 10 m with shielded cable. The fan must be designed for operation with a frequency inverter (EMC-compliant fan/motor, possibly special version). The frequency inverter is permanently set to its rated current. For inverter operation, the suitability for frequency inverter must be specified when ordering the fan.
