Our Three-phase/Three-wire type EMI Filter can be used for Single-phase input.

Attenuation characteristics at three-phase and single-phase are shown below (ex. TAC-30-683), and confirmed that there is no big difference between them.

Rated input voltage of Three-phase EMI filter is AC500V, but it can be used for AC100V or AC200V input as well.
