What is the difference between a sine wave inverter and a correction wave

1. Adjusting sine wave inverters usually uses non protective coupling circuits, while pure sine wave inverters use protective coupling circuit design concepts. Their prices also vary greatly. Adjusting the sine wave power switch inverter not only saves heavy power frequency transformers, but also further improves the inverter efficiency by 95%.
2. Adjusting the sine wave power supply switch mode inverter by using PWM pulse width modulation method to convert it into adjustable wave output. Throughout the inverter process, the use of specialized intelligent power supply circuits and power field-effect transistors significantly reduces the output power consumption of the system software. And it enhances the soft start function, reasonably ensuring the reliability of the inverter power supply.
If the quality regulations for electricity consumption are not very high and it can meet the requirements of the vast majority of electricity consuming machinery and equipment, but it still has 20% harmonic distortion, which can cause difficulties in operating high-precision machinery and equipment and also cause high-frequency interference to communication equipment.
Adjusting sine waves is relative to sine waves, and the popular output waveform of inverter power sources nowadays is adjusting sine waves. The waveform key of inverter power supply can be divided into two categories: sine wave inverter (i.e. pure sine wave inverter) and square wave inverter power supply. The sine wave inverter outputs the same or even stronger sine wave AC current as the power grid commonly used by people, as it cannot detect electromagnetic pollution in the power grid.
The functions of sine wave inverters
● Inverter output function: After turning on the "inverter switch (IVTSWITCH)" on the front panel, the inverter converts the direct current energy of the battery into pure sine wave alternating current, which is output by the "AC output (ACOUTPUT)" on the rear panel.
● Automatic voltage stabilization function: When the voltage of the battery pack fluctuates between the undervoltage point and the overvoltage point, and the load changes within the rated power, the equipment can automatically stabilize the output.
● Overvoltage protection function: When the battery voltage exceeds the "overvoltage point", the equipment will automatically cut off the inverter output, and the front panel LCD will display "overvoltage", while the buzzer will emit a ten second alarm sound. When the voltage drops to the overvoltage recovery point, the inverter will resume operation.
Undervoltage protection function: When the battery voltage is below the "undervoltage point", in order to avoid damage to the battery due to over discharge, the equipment will automatically cut off the inverter output. At this time, the front panel LCD displays "undervoltage", and the buzzer emits a ten second alarm sound. When the voltage rises to the "undervoltage recovery point", the inverter resumes operation; If a switching device is selected, it will automatically switch to the mains output when undervoltage occurs.
Overload protection function: If the AC output power exceeds the rated power, the device will automatically cut off the inverter output, and the front panel LCD will display "overload". At the same time, the buzzer will emit a ten second alarm sound. Turn off the "Inverter Switch (IVTSWITCH)" on the front panel, and the "Overload" display will disappear. If it is necessary to restart, it is necessary to check and confirm that the load is within the allowable range, and then turn on the "inverter switch (IVTSWITCH)" to restore the inverter output.
Short circuit protection function: If there is a short circuit in the AC output circuit, the equipment will automatically cut off the inverter output, and the front panel LCD will display "overload". At the same time, the buzzer will emit a ten second alarm sound. Turn off the "Inverter Switch (IVTSWITCH)" on the front panel, and the "Overload" display will disappear. If you need to restart, you must check and confirm that the output circuit is normal before turning on the "Inverter Switch (IVTSWITCH)" to restore the inverter output.
● Overheat protection function: If the temperature of the internal control part of the chassis is too high, the device will automatically cut off the inverter output, and the front panel LCD will display "overheating". At the same time, the buzzer will emit a ten second alarm sound. After the temperature returns to normal, restore the inverter output.
● Battery reverse protection function: The equipment has a complete battery reverse protection function. If the positive and negative polarity of the battery is reversed, the fuse inside the chassis will automatically blow to avoid damage to the battery and equipment. But reverse connection of batteries is still strictly prohibited!
● Optional mains power switching function: If the mains power switching function is selected, the device can automatically switch the load to mains power supply in the event of battery undervoltage or inverter failure, thereby ensuring the power supply stability of the system. After the inverter is working normally, it will automatically switch to inverter power supply.
