Superior voltage regulation of +/-1% sets the CVS series apart from other power conditioning technologies on the market. Extremely tight regulation is accomplished by SolaHD's ferroresonant transformer technology. The CVS recreates a well regulated sinusoidal waveform that is well isolated from input disturbances including Impulses, Swells, Brownouts, Sags, Severe waveform distortion. No other power conditioning technology provides as complete a solution against these power quality disturbances. The CVS series is Ideal for applications where even a small change in voltage level can lead to unscheduled downtime, misoperation, incorrect data or scrapped production.
