CVS Series power conditionerCVS Hardwired Series Power Conditioner - Constant Voltage Transformers

Superior voltage regulation of ±1% sets the CVS Series power conditioner apart from other power conditioning technologies on the market. Extremely tight regulation is accomplished by SolaHD’s patented ferroresonant transformer technology. The CVS Series power conditioner recreates a well regulated sinusoidal waveform that is well isolated from input disturbances including impulses, swells, sags, brownouts and severe waveform distortion.

No other power conditioning technology provides as complete a solution against these power quality disturbances. The CVS series power conditioner is ideal for applications where even a small change in voltage level can lead to unscheduled downtime, misoperation, incorrect data or scrapped production.
