Q&A(FAQ) How to Use a Three-Phase EMI Filter with Single-Phase Input?
Our three-phase/three-wire EMI filters can also be used with single-phase input.
The attenuation characteristics for both three-phase and single-phase operation (example: TAC-30-683) are shown below, and there is no significant difference between them.
The rated input voltage of a three-phase EMI filter is AC 500 V, it can also be used with AC 100 V or AC 200 V input.
