The main function of an inverter power supply is that the frequency and voltage can be adjusted independently within certain ranges, without one affecting the other. The reason for the development of variable-frequency power supply products was that the standard voltage frequencies for electricity use varied in different regions; as a result, many electrical appliances failed to function properly when exported to those regions. Variable-frequency power supplies were created to solve this problem. So, can the frequency of the variable-frequency power supply be changed? The frequency adjustment range of conventional variable-frequency power supplies is generally divided into three levels: 50HZ, 60HZ, and 40–70HZ. Since the internationally standard power frequencies are mainly 50HZ and 60HZ, these two values are provided to facilitate the use of power supplies for import and export purposes. The adjustable range of 40–70HZ is intended to meet the needs of universities and research institutions that require experiments simulating different frequencies. Of course, some users may require other specific frequency ranges; you just need to provide the product parameters you need, and it can be customized. The main functions of an inverter power supply are to change the frequency and voltage, while also stabilizing both of them, thereby providing load devices with a high-quality, pure sine wave current supply.
