Systemair Frequency converter FRQ5S-10A - 208-480V, 3~, 10A, IP54, 5 steps, LED

Speed controller with 5-step switch for 3~ fan with all pole sine filter Maximum factory-set output frequency: 50Hz 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 Integrated 5-Step switch Step0=0Hz; Step1=10Hz; Step2=20Hz; Step3=30Hz; Step4=40Hz; Step5=50Hz 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 ...
