This series of voltage regulators can be widely used in industry (such as chemical industry, metallurgy, instrumentation, 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. It must be well grounded to ensure safety;
3. When in use, it should always be noted that the output current does not exceed the rated value, otherwise it is easy to reduce the service life of the equipment or even burn out
4. When in use, rotate the hand wheel slowly and evenly to avoid brush damage or spark;
5. The use condition shall be checked frequently. In case of excessive wear and defect of the brush, 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 surface of the coil in contact with the brush shall be kept clean, 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 with cotton yarn stained with alcohol until the spots on the surface are removed;
7. From the power supply to the voltage regulator, the conductor and conductor terminal of the voltage regulator to the load shall be in good contact and can pass through
8. The hand wheel shall not be used when moving, but the handle or the whole product shall be lifted and moved;
9. When it needs to be installed horizontally on the large panel or vertically on other bases, it can be fixed by using the mounting hole of the voltage regulator base;
10. Protect and clean frequently, do not allow water droplets, oil stains, etc. to fall into the interior, and regularly cut off the power to remove the accumulated dust inside;
This series of voltage regulators shall be used indoors under normal service conditions:
1. Ambient temperature: - 15 ℃ ~ + 45 ℃;
2. The altitude shall not exceed 1000m;
3. Relatively moderate: ≤ 90%;
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.
