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.

Use Conditions, Installation and Transportation and Storage Conditions
3.1
Environmental conditions
3.1.1 The altitude of the installation site must not exceed 2,000m.
3.1.2 Ambient temperature
40 °C,and the average temperature within 24 hours shall not exceed 35 °C
°C.
3.2
Installation conditions
3.2.1 For indoors use, and the products cannot be used in parallel; the inclination of the mounting surface to the horizontal
plane must not exceed 5°; the installation site should be free from shaking and shock.
3.2.2 The waveform of the supply voltage should be approximately sinusoidal. For a three-phase regulator, the three-phase
input supply voltages should be approximately symmetrical.
3.3
Transportation and storage conditions
