The role of the voltage regulator is the most obvious and prominent point is that it can fluctuate the current of electrical appliances output voltage control in a fixed value range to ensure the smooth circuit and the normal use of electrical appliances.
Voltage regulator as a circuit of the main equipment, in the start-up, it will begin to generate pressure, and with this pressure to compensate for a circuit due to temperature rise caused by volume changes, and then through the spray and heater, to maintain the balance of pressure with a circuit. When the first circuit becomes overpressurized, the pressure in the first circuit is reduced by transferring steam from the regulator through a safety valve into a pressure relief tank.

< p>The way to buy a voltage regulator:
1, first of all, we should have to understand what types of voltage regulators, in order to buy the one that suits your needs. It is generally divided into two types of inductive regulators and dry regulators, of which dry regulators can be subdivided into CNC regulators and contact regulators. Different types of voltage stabilizers are used for different purposes, and the effects of voltage stabilizers also vary.
2, in addition, from their own needs and the function of the circuit can withstand the fluctuation of the size of the two perspectives, the choice of different sizes and models of the voltage regulator. Generally speaking, home appliances or small laboratories are used in a few watts to a few kilowatts of AC voltage regulator, buy a small voltage regulator can be.
And used in medical equipment, industry and large laboratories and other places of the regulator, will choose tens to hundreds of kilowatts of large power regulator. In addition to this, it is also important to note whether the output current of the regulator is DC or AC, some regulators can turn AC into DC, while others just keep DC all the time.
