Applications
The 3-phase filters are designed to reduce interference in equipment with balanced or unbalanced loads. Wye and delta designs satisfy the connection requirements of these power distribution systems. In addition, L and T circuit configurations are provided for high- and low-impedance loads. A 100 μH inductor is included in the ground circuit to provide ground current isolation.
