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.

EMC filter solutions for industrial applications like motor drives and machine tools. Furthermore, these types of filters are also suitable for mainframe computer systems, large uninterruptible power supplies, medical equipment, wind turbine power stations and a vast array of other threephase power electronics.

Application
Filters are used to suppress circuit-bound interferences in AC power lines.
Interference pulses or interference voltages are dampened independently from their point of origin. To improve the filter effect they are designed with more stages, furthermore these filters have a high insertion loss on a broad frequency range.
Functional principle
The filters are connected between the AC voltage supply and the consumer, which is susceptible to interference. Because of the combination of chokes and film capacitors of the classes “X” and “Y” an effective suppression on a wide frequency range is achieved.
