恒定电压变压器
Superior voltage regulation of ±1% sets the CVS Series apart from other power conditioning technologies on the market. Extremely tight regulation is accomplished by Sola/Hevi-Duty"s patented ferroresonant transformer technology. The CVS recreates a well regulated sinusoidal waveform that is well isolated from input disturbances including impulses, brownouts, severe waveform distortion, swells, and sags. 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 amount of change in voltage level can lead to unscheduled downtime, mis-operation, incorrect data or scrapped production.- .
