Epcos EMC filters offer outstanding attenuation for long motor leads:

Epcos has increased its range EMC filters by introducing its new series of 3 line EMC filters for frequency converters. The new range of 3 line filters is distinguished by offering outstanding attenuation properties which offer major advantages, especially when using long motor leads.

The new range of EMC filters (Series B84143D*R127) are suitable for currents from 16 amps to 200A at a rated voltage of 520V. With a high rated ambient temperature of 50C this new range of EMC filters is suitable for applications such as switching cabinets as well as pumps, HVAC, conveyor systems and printing machines.

When using the Epcos range of EMC filters in conjunction with Epcos SineformerTM output filters (series B84143V*R127) you will see that the EMC limits can be extended to leads of over 500m, depending on the converter type. The sinformer filters also make shielded motor leads unnecessary whilst nearly eliminating all motor bearing currents. The combination of using high performance Epcos EMC filters and output filters offers complete EMC protection and therefore enhances the service life of relevant equipment and significantly reduces system costs.
