New 1-stage filter for 3-phase systems

The slim housing, with a width of just 44mm, requires extremely little space on the mounting rail in the control cabinet. The single-stage filter is available as a standard version or with high attenuation (High Performance: HP). A metal base plate ensures grounding to the rail. The FPAC RAIL series has low leakage current of just 1.3mA.  

One challenge in control cabinets for industrial applications in the 3-phase range, e. g. for motor drives or control systems, is the space required for components. The FPAC RAIL series addresses this problem with a completely new filter design. The new single-stage filter series is constructed with a printed circuit board in a plastic housing. It has screw terminals for the three phases and a terminal on the metal base plate for optimum ground connection to the rail.

In the standard version with ferrite cores, the new filters score with very good attenuation characteristics of up to 85dB, which is already significantly (10-15%) better than comparable alternatives. With the optional HP version by using nanocrystalline cores, the attenuation performance in the frequency range of 10-300kHz can be increased by up to a further 8dB.4

All 16 variants can be used at temperatures ranging from -40 to +100°C. The filters are designed for currents from 3 to 32A at a maximum of 520 VAC, in accordance with IEC and UL standards. They are ENEC and cURus certified and are suitable for applications in accordance with IEC 62368-1.
