3-phase with Neutral Line filters
3-phase with neutral line filters are a compact solution for interference suppression on the mains input of cabinets and control units of equipment, ranging from industrial applications like machine tools to sensitive medical installations. These installations typically involve several and often insufficiently filtered frequency inverters and SMPS, causing current imbalance and significant interference problems. As individual elements, they may be interference-suppressed already. The conjunction of several switching components in the same cabinet and a non-EMC-conscious cabling will increase the demand for an additional EMC/EMI filter on the mains input of the whole installation. Many times, this is the only way to get the CE mark for the cabinet in accordance with the EMC directive.
