The voltage stabilizer shows overvoltage or undervoltage how to deal with?
Usually the power distribution voltage is not 220V, 380V, the low three-phase power is more than 200 volts, the high one is 400 volts, and the single-phase power is the same. The high and low voltages sometimes differ greatly, so before we buy the voltage stabilizer, we need to have a measurement on the electrical sample used. The voltage stabilizer manufacturers will set the minimum and maximum voltage value of the user of the voltage stabilizer according to the electrical sample, and then obtain the fluctuation range value of it. Then according to the obtained the output voltage fluctuation value indicates the most suitable voltage stabilization range of the voltage stabilizer, and generally, when choosing the voltage stabilization, the voltage stabilization range of the voltage stabilization range is wider than the actual range. Regardless of the regulator produced by the regulator manufacturer, no matter what type of regulator, there will be some voltage stabilization range. The so-called voltage stabilization range is based on the normal voltage value as a starting point and can accept the highest voltage. The ratio of the voltage to the lowest voltage. If it exceeds this range, it is overvoltage, and if it is below this range, it is undervoltage. So what should I do if the output voltage of the regulator is too high or too low? Can we adjust ourselves?

What are the differences between regulated power supply and switching power supply?
There are many types of regulated power supplies. Series-type stabilized power supplies are composed of power transformers, rectifier elements, filter capacitors, adjustment elements (adjustment tubes or three-ray regulators, etc.), reference voltage, sampling network, comparison expansion, and overload or short circuit protection and other combinations. Because the series-type stabilized power supply is a linear stabilized circuit, and the regulator tube is stable. Its disadvantages are high power consumption, low efficiency and small scale of fluctuations in the grid. Generally, the series regulated power supply allows the grid fluctuation scale to be 220&±22V. In order to reduce power consumption and improve efficiency, a switch-type regulated power supply is introduced.

How to choose a 3 Phase Stabilizer?
First of all, it depends on the type of your electrical equipment. Generally, the load is not purely resistive. Therefore, in practice selection, the stabilized power supply should be selected reasonably according to the details of the additional power, power factor and load type of the electrical equipment, and its output power should be left with appropriate margin, especially the margin for impact load selection. To be bigger, how to choose the 3 phase stabilizer is as follows:

What should be paid attention to in the wiring of three-phase AC voltage stabilizer
First, the diameter of the power cord at the inlet end of the 3 phase stabilizer should meet the current value of the corresponding capacity of the voltage stabilizer;
Second, the incoming power cord should be connected to the input end of the 3 phase stabilizer, and according to the color of the bus: yellow connects to phase A, green connects to phase B, red connects to phase C, and the outlet power cord should be connected to the stabilizer The output terminal, and according to the color of the busbar: yellow to A phase, green to B phase, red to C phase, to the terminal with zero "N", the chassis shell should be connected to the earth, and the grounding resistance should be less than 0.4 ohm;
