K Series General Purpose RFI Power Line Filters Best Buy for High Impedance Load 1, 2, 3, 5, 10A Models VK7/EK7 VK6 UL Recognized CSA Certified VDE Approved K Series The K series RFI power line filters are general purpose common-mode and differential-mode filters. They are effective in the control of line-to-line as well as line-toground RFI interference. The K series RFI filters are particularly suited in applications where pulsed, continuous and/or intermittent RFI interference is present. The EK models meet the very low leakage current requirements of VDE portable equipment, and (120 Volt) UL544 nonpatient medical equipment.
