This series of voltage regulators can be widely used in industry (such as chemical industry, metallurgy, instruments and meters, electromechanical manufacturing, light industry, etc.), scientific experiments, public equipment and household appliances to achieve the purposes of voltage regulation, temperature control, speed regulation, light regulation and power control. It is an ideal AC voltage regulator
1.The power supply voltage shall comply with the input voltage on the nameplate of the voltage regulator;
2. The voltage regulator must be well grounded to ensure safety;
3. When using, always pay attention that the output current does not exceed the rated value, otherwise it is easy to reduce the service life of the voltage regulator or even burn out
4. Rotate the hand wheel slowly and evenly during use to avoid brush damage or spark;
5. The use of the voltage regulator shall be checked frequently. If the brush is found to be excessively worn or damaged, the brush of the same specification shall be replaced in time, and the hand wheel shall be rotated several times with No. 0 sandpaper under the brush to make the bottom surface of the brush smooth and in good contact before use;
6. The contact surface between the coil and the brush shall be kept clean frequently, otherwise it is easy to increase the spark and burn the coil surface. If black spots are found on the surface of the coil, wipe them off with cotton yarn stained with alcohol until the spots on the surface are removed;
7. From the power supply to the voltage regulator, the wire and wire terminal of the voltage regulator to the load shall be in good contact and can pass through
8. When moving the voltage regulator, the hand wheel shall not be used, but the handle or the whole product shall be lifted and moved;
9. When the voltage regulator needs to be installed horizontally on the large panel or vertically on other bases, it can be fixed by using the installation hole of the voltage regulator base;
10. The voltage regulator shall be protected and cleaned frequently, and water droplets, oil stains, etc. are not allowed to fall into the regulator. The voltage regulator must be powered off regularly to remove the accumulated dust inside;
Precautions for use: this series of voltage regulators should be used indoors under the following
normal conditions:
1. Ambient temperature: - 15 degree plus 45 degree ;
2. The altitude shall not exceed 1000m;
3. Relatively moderate: Less than or equal to 90 percent ;
4. Power supply voltage waveform: the power supply voltage waveform is approximately sinusoidal;
5. The installation site shall be free of gas, steam, chemical deposition, dust, dirt and other explosive and aggressive media that seriously affect the insulation of the voltage regulator; The installation site shall be free from serious vibration or turbulence;
6. Indoor use;
7. It is not allowed to use multiple units in parallel, otherwise the voltage regulator will be burned out.
