A new series of 3-line EMC filters for frequency converters and other power electronics applications is available from TDK-EPC. The use of improved materials has led to a particularly cost-effective design of these input filters.
All types of the B84143*166 series have UL/CSA approval and are designed for currents of 10, 20 or 35 A at rated voltages of 520 or 300 V a.c. These filters satisfy protection class IP20 specifications and are suitable for operating temperatures of up to 50°C. Their electrical design is optimised for short motor leads of up to about 10 m to industry limit value class C2. The filters are contacted via tab connectors or clamp terminals, depending on the type.
