This family of plug-and-play AF series CleanSweep® AC EMI filters is configured “in reverse” providing maximum attenuation of conducted emission coming from the equipment. If your equipment generates excessive noise that cannot be controlled by “regular” EMC approach, this “EG” series EMC filters may be an answer. http://www.felcro.co.id These filters excel where the majority of regular filters fail to perform – common mode noise reduction at very low frequencies below 500 kHz as seen in the graphs. “EG” filters provide noise reduction in differential and common modes and, uniquely, in ground.
