modified sine wave inverter: static inverter

An inverter is an electronic device that converts low-voltage direct current into 220 volts alternating current. In daily life, it is usually used to rectify 220-volt alternating current into direct current. The function of the inverter is the opposite, so it is named "inverter".

The modified sine wave is relative to the sine wave, and the output waveform of the mainstream inverter is the modified sine wave. The waveform of the inverter is mainly divided into two types, one is a sine wave inverter (that is, a pure sine wave inverter), and the other is a square wave inverter(low-frequency pure sine wave inverter). The output of the sine wave inverter is the same or better sine wave AC power as the grid we use daily because it does not have electromagnetic pollution in the grid.

What should I pay attention to when using the inverter?

Use the inverter according to the specifications; the output voltage of the inverter is 220 volts AC, in a small space, and in a movable state to prevent electric shock. When not in use, cut off the input power. The working environment temperature of the inverter should not exceed 45 degrees. The inverter will generate heat when it is working. Do not place objects near or on it. Do not sprinkle water on the inverter if it is afraid of water.

Comparison of pure sine wave inverter power supply with other inverter power supplies:

The output of most inverters has higher harmonics, especially the higher harmonic content of modified sine waves. The national standard stipulates that the harmonic content of sine waves is not more than 5%. Therefore, most sine wave inverters are loaded with speakers. There will always be high-frequency whistling. The technology adopted by our company has a harmonic content of less than 3%, which can be widely used in speakers, power amplifier equipment, etc.

what is a static inverter


Real-time protection function. When the output is short-circuited or overloaded, the traditional inverter power supply adopts single-chip microcomputer control mode, and the response speed is slow. This inverter power supply adopts real-time sampling technology with fast response speed and can protect the equipment and load from damage in time.


The output voltage ripple is small, and the ripple coefficient is less than 3%. The intelligent temperature cooling system, the product is anti-vibration, low working noise, and high conversion efficiency.


Self-starting function. When the input voltage is abnormal or the temperature exceeds the temperature, the output will be automatically turned off and the sound and light alarm will be activated. After the fault is removed, the normal working state will be automatically restored. Large starting power. This machine adopts low-voltage and high-current start mode, which can start the load with a larger power, and has the function of 2 starts.
