Compact Power Entry Module with Ground Line Choke

Schurter's popular power entry module, KFA series, is now equipped with an additional ground line choke to suppress high frequency interference arising from ground loops on the ground line. In addition, the newly added ground line choke improves asymmetric attenuation in higher frequencies in medical filter versions. The KFA series with existing common-mode choke on the phase and neutral conductors, together with an additional ground line choke, is well enhanced to address the growing EMC challenges facing compliance engineers today.

The KFA power entry module includes an IEC C14 power inlet connector with a 1- or 2-pole fuseholder and EMC filter and is available in a wide range of models and designs. The series offers current levels from 1A to 10A at 250 VAC according to IEC and UL standards.

The series has ENEC and cURus approvals and is suited for applications according to IEC 60950. Special filter versions, M5 and M80, are available for medical devices according to IEC 60601-1. Wiring is done using quick-connect terminals or wire leads. The KFA is compatible with V-Lock cord sets, designed to safeguard against unintentional disconnection of the power.
