Voltage regulators have the characteristics of waveform distortion free, small size, light weight, high efficiency, convenient use, reliable performance, and long-term operation. They achieve the purpose of voltage regulation, temperature control, dimming, power control, etc. They are widely used in chemical, metallurgical instruments, electromechanical manufacturing, light industry, scientific experiments, public facilities, household appliances, temperature control and speed regulation, dimming, and power control. They are an ideal AC voltage regulation power supply.

1. Environmental temperature: * * Temperature+40 ℃, * * Temperature -5 ℃.

2. Altitude: The installation location of the voltage regulator has an altitude not exceeding 1000 meters.

3. Relative humidity of the air: The average relative humidity of the wettest month is 90%, and the average temperature of that month is 25 ℃.

4. Power supply voltage waveform: The power supply voltage waveform is a sine wave or similar to a sine wave.

5. The installation location does not have any gases, vapors, chemical deposits, dust, dirt, or other explosive and corrosive media that seriously affect the insulation of the voltage regulator;
6. The installation site should be free from severe vibrations and bumps;
