Helios FU-BS 8.0

Frequency converter in basic design with integrated, all-pole effective sine filter for speed control of one or more fans. The permissible number of fans is determined by the maximum converter current. Speed setting is done via the 0-10 V control signal (e.g., potentiometer PU/PA, accessories). A cable length of over 10 m between the converter and the fan is possible. No additional EMC shielding of the electrical lines is required. The fans, including the motor, do not require special EMC precautions for frequency converter operation. The converter is fixedly set to its rated current. When using the frequency converter with integrated sine filter, conventional standard fans/motors can be used.
