These pulses are easily transmitted through\u003cbr\u003e\nthe AC power lines which can then enter other\u003cbr\u003e\nequipment wired to the same line. In addition, once\u003cbr\u003e\nthe interference is allowed to conduct through the\u003cbr\u003e\npower lines, the wires become radio antennas which\u003cbr\u003e\nactually radiate electromagnetic energy through the\u003cbr\u003e\nair. The energy, whether conducted or radiated, is\u003cbr\u003e\ncalled Radio Frequency Interference (RFI) and is most\u003cbr\u003e\npronounced between .5MHz–1.5MHz, which is the AM\u003cbr\u003e\nbroadcast band. Although the interference is usually\u003cbr\u003e\nnot noticeable, except for static on an AM radio, it\u003cbr\u003e\ncould affect sensitive electronic equipment in some\u003cbr\u003e\ninstances. The KBRF-200A is an RFI filter which has\u003cbr\u003e\nbeen designed to limit the interference to within\u003cbr\u003e\nacceptable levels as determined by the CE Council\u003cbr\u003e\nDirective 89\/336\/EEC relating to EMC. The unit is\u003cbr\u003e\ncompact in size (approx. 4.4\" L x 2.9\" W x 1.5\" D) and\u003cbr\u003e\ninstalls easily via quick-connect terminals. It is housed\u003cbr\u003e\nin a plated steel case which is to be grounded via an\u003cbr\u003e\nexternal ground screw or mounting tab. Complete\u003cbr\u003e\ninstallation instructions are included.\u003c\/p\u003e","brand":"Industrial Motors","offers":[{"title":"Default Title","offer_id":51663128133954,"sku":"KBRF-200A","price":57.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/2298\/4002\/files\/kbrf-200a-kb-electronics.jpg?v=1766406149","url":"https:\/\/industrialmotors.com\/products\/9945-ce-approved-ac-line-filter-class-a","provider":"Industrial Motors","version":"1.0","type":"link"}
