The DSFi is designed to provide secondary protection against power surges caused by external sources such as<br />
lightning strikes and substation switching as well as providing a measure of protection from surge events generated<br />
on the secondary side of the filter.<br />
<br />
Low-Q LC filter (i.e. 2 inductive coils) using separate differential mode and common mode circuits. The unit provides<br />
filtering of the line harmonics, noise and RF transmitters with a cut-off frequency of 55dB to 10MHz.<br />
<br />
protect against load-generated surges. An ideal device for Category B and A locations.<br />
