FRQS-E-6A

Speed controller with 0-10V input for 1~ fans equipped with all pole sine filter

Maximum factory-set output frequency: 50Hz

The FRQS-E frequency inverters have integrated all pole sine filters as standard. Therfore there is no need for shielded cables for the installation. This makes the unit also perfectly suited to retrofit into existing systems. The sine filters enable existing non-shielded cables to be retained. This units also reliably control motors which, due to their design, are not usually considered suitable for frequency inverter operation i.e. external rotor motors.
