series full-automatical voltage regulator consist of contact autotransformer,servomotor,automatic control circuit etc.When grid voltage or load is changedautomatically sampling control circuit sends a signal to driveservomotor,adjust theposition of the self coupling voltage regulator for carbon brush,make the outputvoltage rating reach the stable state
This product has the waveform distortionless,reliable performance.long-termoperation and other characteristics,such as time delay,over voltage,undervoltageprotection.It can bewidely used in electricitywhich need stablevoltage,it is an idealvoltage stabilized supplytoensurethe normal operationof electricalequipment.
