As an important component of electrical equipment, the automatic voltage regulator AVR has the function of stabilizing voltage output and is often used in households. So, when we need to choose a voltage stabilizer for an electrical device with a power of 1200W, how big a voltage stabilizer do we need to purchase? This article will give you a detailed introduction to how to choose a suitable voltage stabilizer.
The capacity selection of household automatic voltage stabilizers should consider two important factors: power and pressure.
Power refers to the electrical energy required by the device, while pressure refers to the voltage input of the power supply. When choosing a voltage stabilizer, we need to confirm the power of the device and the voltage of the power supply.
Understand the power of the device.
For a device with a power of 1200W, we can determine that the power it requires is 1200 watts. Therefore, when choosing an automatic voltage regulator, we should choose a voltage stabilizer with at least 1200W capacity, to ensure that the voltage stabilizer can meet the power requirements of the device.
Rated power of automatic voltage regulator
The rated power of the automatic voltage regulator should also reserve a part of the margin to cope with the additional power demand of the equipment at startup or peak load. Generally speaking, it is recommended to add a 20% margin based on actual power demand, to ensure that the voltage regulator will not be overloaded during operation and extend the service life of the voltage regulator.
Consider the voltage of the power input
When choosing a voltage regulator, it is necessary to confirm the stability of the power input voltage and whether the voltage needs to be adjusted. The power supply voltage in some areas may fluctuate or be unstable, so we may need to choose a voltage regulator with a voltage adjustment function.
Rated capacity table
After confirming the power of the equipment and the power input voltage, we can refer to the rated capacity table of the automatic voltage regulator to select a suitable voltage regulator. The rated capacity table usually provides the required voltage regulator capacity of equipment with different power ranges and the applicable input voltage range. According to the power of the equipment and the power input voltage, the corresponding voltage regulator model and capacity can be found.
Other functions
pay attention to some special functions of the voltage regulator. For example, some voltage stabilizers have functions such as overload protection, under-voltage protection, and temperature protection, which can better protect the equipment and the voltage stabilizer itself, and improve the safety and reliability of use.
To choose a suitable voltage stabilizer for an electrical device with a power of 1200W, we need to confirm the power demand of the equipment and the power input voltage.
When choosing an automatic voltage regulator, you should choose a voltage stabilizer with sufficient capacity and reserve a certain margin. At the same time, consider the stability of the power supply and the need to adjust the voltage, and choose a suitable voltage stabilizer model and capacity. Finally, pay attention to the special functions of the voltage stabilizer to improve the safety and reliability of use. I hope this article will help you choose a suitable automatic voltage regulator for home use!
