TND/TNS series automatic AC voltage stabilizer consists of a contact-type voltage regulator and an automatic control circuit. After sampling and amplifying the output voltage, the servo motor is controlled to drive the electric brush components rotate in the required direction on the annular voltage regulating coil friction surface allowing the output voltage is adjusted to the rated value for obtaining stable voltage.
The product can be widely used in power supplies of many electrical equipment and facilities such as office equipment, debugging instrument, communication system, industrial equipment, medical equipment, and household appliances.
