EMI filter AC 230V 20A DIN rail

This is both a common-mode and differential EMI (electromagnetic interference) filter for 230V AC, max. 20A. Designed for DIN rail mount with multiple outputs, it is the ideal filter for the main supply to a cabinet where multiple AC to DC sources follow.

Differential filtration mode: two differential inductors perform differential AC filtering to suppress mid and high frequency interference. The common-mode filter is combined through an X2 capacitor and a common-mode inductor. The two-stage common-mode filtering has a better noise filtering effect - it can suppress the problem of fast transient interference by group pulses with a repetition rate of several thousand Hz at some user locations. Use it as an input filter for multiple devices, for DIN rail mounting, decreasing high-frequency electronic noise, as a common-mode and differential line filter, an additional filter for linear and switching mode PSUs, or as a filter for a common 230V AC plug.
