What's the role of imperial party in stabilizing the spirit?

Useful. The function of the voltage regulator is to stabilize the voltage. If the line spacing is too long and the line diameter is not enough, the voltage will drop. In addition, if large-scale equipment is started on the same line, it will cause voltage fluctuation across the line, which is very unfavorable to the operation of equipment or household appliances. Therefore, the voltage regulator can solve these problems well. As long as the input voltage is within the input range of the voltage regulator, the output voltage can be stabilized at single-phase 220V and three-phase 380V, providing stable power output for the equipment.
