Nowadays, the voltage in many households is not very stable, and at this time, it is necessary to purchase a voltage regulator to use. Many friends did not understand the voltage regulator before buying it, so they randomly bought one. After receiving the goods, they found that the voltage regulator was too small and the power was not enough to use, resulting in the need to return and exchange it, causing unnecessary shipping costs and wasting time and money. Here, the official flagship store of Delixi will explain how to correctly select the power size of the voltage regulator.

    Firstly, it depends on the type of electrical equipment you are using. Generally, the load is not purely resistive. Therefore, in actual selection, it is necessary to choose a regulated power supply reasonably according to the specific conditions such as the rated power, power factor, and load type of the electrical equipment. The output power should have an appropriate margin, especially when selecting impact loads, the margin should be larger.

How to choose the power of the voltage regulator specifically:

1. For purely resistive loads such as incandescent lamps, resistance wires, induction cookers, etc., the voltage regulator power should be 1.5 to 2 times the power of the load equipment. For example, if your induction cooker has a power of 250W, you can choose a voltage regulator with a power of 500W.

2. Sensory and capacitive loads such as fluorescent lamps, fans, motors, water pumps, air conditioners, refrigerators, etc. The power of the voltage regulator should be three times the power of the load device. For example, if the electric motor is 1000W, the rule for selecting a voltage regulator is 3000W.

In environments with large inductive and capacitive loads, the starting current of the load should be considered when selecting, which is particularly large (up to 5-8 times the rated current). Therefore, when selecting a voltage regulator, the power should be at least 3 times the load power.
