6A EMI Filtering Audio Power Filter Power Purifier 50/60HZ AC

Introduction Widely used in precision measuring instruments building automation precision machinery equipment elevator lifting equipment automation systems calculator office equipment servo system inverter equipment frequency conversion equipment lighting information communication equipment UPS switching power supply automotive electronics On the equipment after using high quality imported components the filtering effect is obvious EMI power filter function The power EMI filter is a reactive low pass filter installed at the power inlet of the electronic device to suppress the noise interference transmitted through the power cable of the power grid and suppress the high frequency interference signal generated by the electronic device itself Enter the power grid and harm other electronic equipment Therefore EMI has become a device that must be installed in electronic equipment Power supply noise is a type of electromagnetic interference and its conducted noise spectrum is approximately 10 kHz to 30 MHz up to 150 MHz Depending on the direction of propagation power supply noise can be divided into two categories one is external interference introduced from the power supply line and the other is noise generated by the electronic device and conducted through the power cable This indicates that the noise is a two way interference signal and the electronic device is both an object of noise interference and a noise source According to the formation character
