Frequency converter in basic version with integrated all-pole effective sine filter. For controlling the speed of one or more fans. The permissible number of fans is derived from the maximum FU current. The speed is specified via the 0-10 V control signal (e.g. potentiometer PU/PA, accessories). Cable length possible over 10 m between FU-BS and fan. No additional EMC-shielding of the electrical wires necessary. The fans including the motor do not require any special EMC precautions for frequency converter operation. The FU-BS is fixed to its nominal current. When using the frequency converter with integrated sine-wave filter conventional standard fans/motors can be used.
