FRQ5 - 4A V2 Inverter Speed Controller

Frequency converter for energy-efficient control of motors
Reliable control
Plug & Play
Energy efficient
Integrated motor-protection with PTC/PTO
Maximum output: 50Hz
Types:
Type FRQ5: with integrated 5-step switch
Type FRQ: with 0-10V input
Type FRQ(5)S: with all-pole sine filter

The FRQ/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"
Interference emission EN 61000-6-3
Interference immunity EN 61000-6-2
Complete range in IP54
Trouble free parallel operation of motors
No danger to the motors through voltage peaks,bearing current,etc.
No limit of motor cable length
Retrofit in installations with existent wiring(unshielded cables)
Operation without electromagnetic motor noise
Wide voltage range 3~ 208V-480V, 50/60Hz

When operating with Explosion proof fans the FRQ has to be placed outside the EX zone!
