UV frequency conversion power supply is used to change domestic 220V50Hz into 110V60Hz, 220V60Hz. Many domestic manufacturers say that they can carry any load. Frequency converter: only suitable for motor drive. Output 220V, 380V, 660V, etc. And the frequency is 0-400Hz. But it can only carry motor load. What is the difference between them in principle.
In the past ten years, the variable frequency power supply composed of the whole circuit composed of AC DC-AC-filter variable frequency device has emerged and is widely used. The variable frequency power supply can not only simulate and output the power grid indicators of different countries in the world, but also provide a pure, reliable, low-distortion, high-stability sine of voltage and frequency for an engineer of an export electrical appliance manufacturer in design, development, production, testing and other applications. Wave power output. The variable frequency power supply is very close to the ideal AC power supply.
In the past, motor generator sets (intermediate frequency generator sets) were often used for frequency conversion. Due to their large power consumption, large noise, large volume, poor accuracy, and pollution, they need to be placed in a separate room and need to be managed by a dedicated person. Replaced by power supply.
