Ferroresonant transformers, also known as constant-voltage or controlled-output transformers, are adjusted for both line and load regulation.
Line Regulation - A variation of input voltage of 15 percent will result in only a 1 percent variation in output voltage.
Load Regulation - A variation in load from 50 percent to full load will result in only a 3 percent variation in output voltage.
