DSFi Series - Dual Stage Surge Filter dsfi_bg

The DSFi provides secondary protection against power surges caused by external sources such as lightning strikes and substation switching as well as providing protection from surge events generated on the secondary side of the filter. Its 3-stage protection unit utilises primary and secondary MOV protection in conjunction with a Low-Q LC filter. In addition, the unit also provide filtering of the line harmonics, noise and RF transmitters.
