Compact single-phase converter filter
Compact single-phase converter filter from Epcos for currents up to 2 x 60A.
Designed to suppress the high levels of interference found on the power lines of frequency converters, the new B84142-A series of compact single-phase converter filters is available in a wide range of nominal current ratings from 2 x 10A right up to 2 x 60A Frequency converters are being used more and more in the field of drive and power electronics for controlling the motion of machinery

PhiCap AC capacitors from Epcos are primarily designed for power factor correction in industrial environments, but can also be used in uninterruptible power supply and drive engineering applications
However, the fast switching power semiconductor components used in the converters generate interference on the power lines.
Based on the successful SIFI model, B84142-A filters suppress such interference to Class A on both the input and output side of frequency converters.
The new filters are ideal companions to the earlier released B84142-B series.
With current ratings of 8 to 25A and a high attenuation characteristic, these units were aimed at providing noise suppression to Class B for single-phase systems such as uninterruptible power supplies operating at 240V.
The new B84142-A filters, meanwhile, offer an ideal alternative for less rigorous requirements, such as Class A noise suppression or where a basic noise suppression unit is already incorporated in the equipment.
Epcos is one of the largest suppliers of passive products worldwide.
The company currently has 15 manufacturing sites across the world, developing and manufacturing some of the most innovative products available.
