Principle of operation

When the unit that measures the input voltage detects a variation
outside the preset range, it will send a signal to the control unit
that will activate the servomotor. The secondary voltage
transformer will change the polarity and magnitude of the
compensation voltage and will control the output voltage within
the preset range.
