Single-Phase EMI/EMC Filter
Single-phase filters for chassis or DIN-rail mounting are key for EMC compliance of higher power office equipment and low to medium power industrial applications. A broad selection of electrical and mechanical features allows a specific choice and deployment for countless applications.

Three-phase and neutral line filters are a compact solution for the 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 typically involve separate 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 rise the demand for an additional EMC 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.

LCR's Single Phase Industrial EMI filters (RFI filters, EMC filters) attenuate electrical noise generated from industrial, telecommunication, commercial, military and medical electrical and electronic equipment. These EMI filters attenuate mains-borne electromagnetic interference from 100 kHz upwards to very high frequencies.

Protection Filters are used on distribution networks which have a high THD (Total harmonic distortion), when the final target is to compensate the power factor at the fundamental frequency.
Its purpose is to avoid overloads due to harmonic currents in the capacitor, deflecting them to the network.
Protection filters are made with serial reactors and capacitors. The tuned frequency of each unit is adjusted between the fundamental and the lower harmonic present in the net, which usually is the 5 th order.
In this way, the filters present high inductive impedance for all the harmonic frequencies.

LCR's 3 Phase EMI filters (RFI filters, EMC filters) are typically used in Power Electronic products. These EMI filters attenuate mains-borne EMI generated back into the power line. LCR's 3 phase EMI filters also protect sensitive electronics and make them less susceptible to surges, Electrostatic Discharge (ESD) and other harmful voltage and current surges. Typical applications for these EMI filters (RFI filters, EMC filters) are in three-phase industrial drives, controllers, frequency converters and industrial machine tools.
