SOLAHD Constant voltage transformer provides 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 ferro-resonant transformer technology. It recreates a well regulated sinusoidal waveform that is well isolated from input disturbances including impulses, swells, brownouts, sags and severe waveform distortion. No other power conditioning technology provides a complete solution against these power quality disturbances. It is ideal for applications where even a small change in voltage level can lead to unscheduled downtime, incorrect data or scrapped production like industrial automation and control equipment PLCs, analytical laboratory and factory automating equipment, broadcast equipment etc.
