This product is further developed based on TND series high-precision automatic AC voltage regulator, with more complete functions. The control system composed of linear integrated circuits is used to control the servo motor, and to drive the contact voltage regulator for automatic voltage regulation, and has delay selection, overvoltage protection and undervoltage protection selection, overcurrent protection and mains direct output functions. It has the advantages of high efficiency, no additional distortion, low power consumption, novel style, and wall-mounted installation.
