Low voltage/high frequency noise is caused by everyday events such as turning on machinery, motors, or equipment. Although noise is less dramatic than high voltage transients, the long term effects of these frequent disturbances can be as damaging. Filtering systems such as Sola Active Tracking Filters provide clean AC power by eliminating lower voltage noise. (read more)
