Three-phase AC voltage regulator

AC voltage regulator is a device used to stabilize the output of AC voltage. It can produce a stable output voltage by adjusting the size and frequency of the input voltage. Ac voltage regulator is usually used in the need for stable voltage power supply, such as laboratories, factories, computer rooms and other places. Among them, the most common is the traditional voltage regulator in the power system and the intelligent transformer popularized in modern science and technology.

Choose AC voltage regulator power need to consider the following points:

1. Load power: The power of the voltage regulator should be selected according to the actual load power used. In general, the rated output current of the stabilizer should be slightly greater than the load current (leaving a margin) to ensure normal operation of the regulator.

2. Ambient temperature: the rated power of the regulator is tested in the standard environment. If the temperature of the working environment is higher than the standard environment, then the heat dissipation capacity of the voltage regulator will be reduced, at this time, the need to choose more power voltage regulator.

3 power supply voltage fluctuation: if the voltage of the input power supply often fluctuates, then choose more power, more stable voltage regulator can ensure that the output voltage is stable.

4. Other factors: If the output voltage of the regulator should not drop beyond its rating during excessive load, otherwise it may be damaged. In the choice of voltage regulator to consider the need to deal with the transient load, such as starting current, to prevent its explosion.

In a word, the choice of AC voltage regulator power is related to the actual scheme application scenario, it is necessary to consider various factors to choose the appropriate power.
