Features

Frequency inverter FU-B in basic version without sine filter for the speed control of a single fan. The speed selection takes place via the 0-10 V control signal (e.g. potentiometer PU/PA, accessories). Cable length between FU-B and fan up to 10 m with shielded cable. The fan must be designed for operation with frequency inverter (EMC-compatible fan/motor, optional special version). The FU-B is fixed at its rated current. For FU-B operation (without sine filter) the frequency inverter capability must be specified when ordering the fan.
