General

  

Use

        TNDZ and TNSZ series pillar type AC automatic voltage regulators (hereinafter referred to as the voltage regulator) are 
mainly used in various places where the load voltage needs to be stablized. When the supply voltage fluctuates, the voltage 
regulator can automatically stabilize the load voltage within the deviation range of the rated value. They are suitable for the 
areas with large fluctuation of grid voltage or large seasonal variation of grid voltage (long-term low or high grid voltage), by 
providing stable power supply for load to ensure the normal operation of powered devices.
