Item Number: 36231
Speed controller with 0-10V input for 3~ fans equipped with all pole sine filter
The FRQS/FRQ5S 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.
Save and trouble free motor operation with integrated, all pole effective sine filter
Analog input for external speed setup value(0-10 V, 0-20 mA, PWM)
10V DC output for external potentiometer
Potential-free operation notification
Enable contact section for a stand-by switch or electronic reset
Motor protection by connecting thermostats "TB" or thermistors "TP"
