With the upgrading and updating of power regulators, the stability and safety of power regulators have been greatly improved due to the use of integrated circuit devices as triggers. Additionally, due to its lightweight, small size, and high efficiency, maintenance is also relatively convenient. However, there are four key points that we need to pay attention to when using power regulators. So, what are the four key points? Below, the editor of Lingben Motor will explain to you the specific content as follows:

1. The limitation of the load characteristics of power regulators used for resistive loads is that when the inductive load is at a certain conduction angle, it may cause the thyristor to not conduct.

2. The influence of power factor on power regulators may lead to a decrease in power factor, especially in the case of "deep control", where the power factor will become lower. If the regulator needs to be used for a long time or more for deep control, appropriate compensation measures should be taken.

3. Define the regulation range of the power supply voltage regulator. The output voltage of the thyristor power regulator is 0-380V (due to the issue of conduction when the input voltage is 380V, as the actual output voltage will be slightly lower than 380V). If the claim is greater than 380V, then an induction regulator (which can be designed to output voltage 0-2X380V) should be considered.

4. Thyristors have many advantages in overvoltage and overcurrent protection, but their ability to withstand overvoltage and overcurrent is poor. Short term overvoltage and overcurrent can cause component damage. Although there is a certain safety factor in the selection of thyristors, certain protective measures still need to be taken. Overcurrent protection generally uses automatic air switches and fast fuses, while overcurrent protection uses resistance capacitance absorption devices and varistors. When not in use, the power should be cut off.

The above are the four key points for using power regulators, hoping to be helpful to everyone.
