TDK:EMC filter compact high performance 3-line EMC filter

TDK has expanded the EPCOS 3-wire EMC filter B84243*'s product range to include 10 filters with currents up to 280A. All 18 filters in this series have a rated voltage of 530VAC. The performance of this series of filters is optimized for EN 61800−3:2004+A1:2011 motor cable limits up to 25m (C1) or 50m (C2). The metal housing of the filter is IP20-protected and comes in two compact sizes of 190 x 40x95 mm and 450 x 170 x 230 mm, depending on the model. Due to the very high saturation impedance of the filter, parasitic asymmetrical currents can be reliably controlled even with extended motor cables.

Another advantage of the new B84243* series is its low leakage current, which enables stable operation even in a 30mA RCD environment. Considering that smaller manual operating equipment requires a leakage current of less than 3.5 mA, the 3A version of the filter (B84243A8003U000) is specifically optimized to have a leakage current of only 1.9 mA at 400 VAC. Another important safety feature is that models rated up to 44A discharge to <60V in less than 1 second.

Typical applications for new filters include elevators, pumps, conveyor systems, and HVAC system drive inverters.
