Purpose：Variable transformers have the characteristics of small waveform distortion, small size, light weight, high efficiency, easy use, reliability, and long-term operation. They can be widely used in industries such as chemistry, metallurgy, instrumentation, electromechanical manufacturing, light industry, scientific experiments, public facilities, and household appliances to achieve voltage regulation, temperature control, speed regulation, dimming, power control, and other purposes. They are an ideal AC voltage regulating power supply. Usage conditions 1. The average ambient temperature is+40 ℃~5 ℃. 2. Altitude: The installation location of the voltage regulator shall not exceed an altitude of 1000 meters. 3. Relative humidity of the air: The average humidity in the wettest month is 90%, and the average temperature is 25 ℃. 4. Current and voltage waveform: The power supply voltage waveform is approximately sinusoidal. 5. There are no gas vapors, chemical deposits, dust, dirt, or other explosive and corrosive media that seriously affect the insulation of the voltage regulator in the installation site 6. The installation site should be free from severe vibration and bumps. 7. Indoor use is not allowed in parallel. 8. Any special usage conditions that do not comply with the above regulations shall be determined through consultation between the user unit and the manufacturing unit. Use and Maintenance 1. Under normal operation, the voltage regulator should regularly check the carbon brushes to ensure that the contact area between the carbon brushes does not exceed two line widths. 2. Regularly check the insulation resistance (test with a 500 megameter when the relative humidity reaches 95%). The insulation resistance between the coil and the base should not be less than 2mm. 3. The three-phase voltage regulation should be checked regularly to check the condition of the carbon brush and adjusted in a timely manner 4. The casing of the voltage regulator should be grounded. After use, adjust the handwheel pointer back to zero and pay attention to cutting off the power
