The 4P-L3 series 3-phase +N+E power filter in line with international certification (SGS) suppression of the required filter performance and easy installation features. This series of filters to install design, especially considering the high attenuation performance required to have symmetry in the line impedance load or load asymmetry. The scope of this series of filter noise suppression, in full compliance with EN133200, UL1283, IEC60950 and VDE 0565 standard. They are very suitable for use in the environmental requirements of EN55011 CLASS A and EN55022 CLASS B. Low leakage current is ideal for use on medical equipment and sports and health equipment.
