It adopts SPWM technology and CPU control, the main circuit power module used the imported modes. It can also convert the DC power of 12V/24V/48V/110V/220V into the sine wave AC power of 220V, 50Hz voltage, frequency stabilization, low noise pure. Its small size, light weight, high efficiency, simple operation, no pollution, as well as it can be used in a relatively harsh environment which equipped it with the advantages of high stability, high reliability, congruent protection. In addition, it is also characterized by the strong non-linear load drive capability which enables the manufacture of the high-power supply.
