How to buy inverter power supply

In-vehicle inverter power supply can be connected to the power converter, and it can be as convenient as various electric appliances in the car at home. Users need to consider more issues when choosing a car inverter power supply. Today, Xiao Bian has come to specifically explain how to buy a vehicle-mounted inverter power supply. I hope to help everyone.

First of all, we must pay attention to the specifications, because the electrical equipment used to support different power needs to use inverters of different specifications. Therefore, we must first know which electrical appliances we are using in different electrical appliances. Otherwise, to buy a 40W specification inverter, but found that a car electrical appliances need 100W power, start-up has become a problem. In addition to purchasing a car inverter, it is necessary to confirm the various protection functions of the inverter, because the car power supply itself is unstable, the inverter does not provide protection, then when the electrical product is connected to the inverter, it is easy to make bad electrical appliances. . In general, the onboard inverter is divided into two types according to the waveform of the output current. One is a square wave converter and the other is a sine wave converter. Because the power supply of the square wave inverter is unstable, the quality of the output AC current is poor, and its load capacity is poor, which is only 40-60% of the rated load, and may damage the used electrical appliances. So samasora recommends that you try to buy a pure sine wave inverter or a modified sine wave inverter. Modified sine wave inverter, also known as quasi-sine wave vehicle-mounted inverter, can be applied to mobile phones, laptops, televisions, camcorders, CD players, various chargers, car refrigerators because its waveform is close to a sine wave. Game consoles, DVD players, and more.

It should be noted that the prices of pure sine wave inverters and modified sine wave inverters are not the same. Pure sine wave inverters are high-end products, and modified sine wave inverters are low-end and mid-range products. The modified sine wave inverter has high efficiency, low noise, and moderate price, and it has become the mainstream product in the market. Finally, when choosing a car power inverter, pay attention to the efficiency of the conversion. Like most electronic products, there are conversion efficiency in the car inverter, and the common inverter conversion efficiency in the market is between 70% and 80%.
