How to choose the right inverter power supply?

Inverter power products on the market can be roughly divided into two types, one is sine wave inverter and the other is square wave inverter. Some engineers also like to divide pure sine wave inverter into another category. That is sine wave, pure sine wave, square wave.

1. Sine wave, its output waveform is just like the wave of the commercial power we use, but its output waveform is better than that of the commercial power, so this product is suitable for all electrical equipment. But its price Higher, generally 300W is sold for more than 800 yuan. Generally, we use Tiangao precision equipment, detection, research and development, military and other places. And for home appliances, we don't need to use any high-demand machines, and low-power power can meet the requirements. needed for living. Therefore, there are not many such products on the market, and they are usually customized by buyers.

2. Pure sine wave inverter, this is a popular product, its conversion efficiency, cost performance are better than sine wave, the applicability of the load is worse than sine wave, but for home appliances, such as TVs, computers , Audio, motors below 1000W, etc., are not much worse than sine waves, and it has a low price. In low-power inverter power supplies, it is the mainstream product.

3. Square wave, square wave, the output is a square wave, its load capacity is poor, for general inductive loads will produce large harmonic components, so for motors, TVs will have relatively large noise. The products were all made with power frequency transformers in the early days, and they have been eliminated.

The above is to analyze the waveforms of three different inverters, we mainly need to understand it.For buyers, the most hope is to know how to determine whether the inverter is suitable for their own use.

Powerwit provides pure sine wave inverters, complete with high power and low power, pure sine wave output, suitable for all resistive and inductive loads. The advanced anti-noise printing technology does not interfere with other public DC communication equipment. It is currently the most popular pure sine wave inverter. For high requirements on power applications, this inverter power supply can be the first choice. This inverter has high efficiency, suitable for unattended function, RS48 communication function, real-time monitoring of the inverter's operation on the computer, and one-key operation of the inverter's faults, which is very convenient and safe.
