VAS Series Three Phase AC Automatic Voltage Stabilizer (Voltage Regulator) | DERLICN

Our company produces SVC (VAS) type three-phase, three-phase AC voltage stabilizer is a new generation of energy-saving multifunctional voltage stabilizers developed and produced by the market’s voltage stabilized power supply.

It consists of contact autotransformer, servo motor, automatic control circuit (using large-scale linear logic circuit) and other components. When the grid voltage is unstable or the load changes, the automatic control circuit will drive the servo motor according to the ratio of the output voltage, adjust the position of the carbon brushes on the top of the autotransformer, and stabilize the output voltage at the rated value.
