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