Relay-type voltage stabilizers accomplish voltage regulations by switching the relays to connect one of several tappings of the transformer to the load.
SVC series fully automatic voltage regulator consists of a contact autotransformer, servo motor, automatic control circuit etc.
When grid voltage instability, the automatic sampling control circuit sends a signal to drive the servo motor
Waveform distortionless, reliable performance, long-term operation
Over-voltage, Undervoltage protected function
