Classification of voltage regulators

The first type is manual voltage regulator: this type of product is the cheapest and has been basically eliminated due to its inconvenient operation
The second type is a fully automatic intelligent voltage regulator: it has the characteristics of large capacity, high efficiency, no waveform distortion, fast voltage regulation response time, and is suitable for a wide range of loads. This series of products is equipped with overvoltage, undervoltage, overcurrent and other protection functions, making it easy to use and install, and reliable to operate. The product adopts the latest DSP operation and measurement chip control technology, fast AC sampling technology, effective value correction technology, current zero crossing switching technology, and fast compensation and voltage stabilization technology. It combines intelligent instruments, fast voltage stabilization, and fault diagnosis together, making the product safe, efficient, and precise. The product mainly consists of an isolation transformer, SCR module, CPU control core, and safety protection device, achieving contactless control. Widely used in large electromechanical equipment, production lines, elevators, medical equipment, embroidery and textile equipment, air conditioning, broadcasting and television, household appliances, and building lighting that require stable voltage in industries, transportation, postal and telecommunications, communication, national defense, railways, scientific research, and other fields  
The third type is relay type automatic voltage regulator: it uses relay switching to adjust the output voltage, which has large voltage fluctuations and relatively low accuracy. Used for mid-range voltage regulators, such as the Boat Wave TM series high-power adapter automatic AC voltage regulator, this type of product has high stability and low price, suitable for equipment with low voltage accuracy requirements.
Some families may actually cause damage to their household appliances after using voltage regulators. The root cause is improper selection and use of voltage regulators: when choosing, there is no margin left, and the voltage regulator is purchased according to the rated power of the household appliance, resulting in long-term full load operation and malfunction of the voltage regulator; If you want to purchase a voltage regulator for electrical equipment with low starting current, such as refrigerators and televisions, the power of the voltage regulator should be 2-3 times that of the electrical appliance; If you want to purchase a voltage regulator for electrical equipment with high starting current, such as air conditioning, you can choose 3-5 times its power. The selection type is incorrect, for example, a relay type power regulator not only fails to protect electrical appliances that require high-precision voltage (such as computers), but also has a negative effect.
During installation, it is convenient to closely adhere to the wall or roof, which may cause poor heat dissipation. Experts suggest that when purchasing a voltage regulator, the rated output capacity should be at least three times the power of the household appliance to be protected; When installing, it should be about 20 centimeters away from the wall or roof to facilitate heat dissipation. The voltage regulator also needs to be regularly maintained during use.
Installation and maintenance of voltage regulators: Installation, wiring, adjustment and other live work must be operated by electricians to avoid electric shock and damage to the voltage regulator during wiring and adjustment.
The ventilation and heat dissipation of the voltage regulator should be good. Do not block or cover the heat dissipation holes with any objects, which may hinder the heat dissipation of the power supply and cause overheating of the voltage regulator. If the temperature rise is too high, please install a cooling equipment fan (usually large voltage regulators have already installed cooling equipment).
Regularly eliminate dust inside the machine, keep the gear coil grinding surface and carbon brush clean. When the carbon brush wears out after long-term work, adjust the contact pressure between the carbon brush and the coil to ensure good contact and avoid sparking.
To ensure personal safety, the casing should be grounded
