變頻器原理

由驅動系統執行的(de)每(mei)個(ge)任務都具有自身的(de)特(te)定要求。因此(ci)，需(xu)要提供可方便而靈(ling)活地加(jia)以(yi)調整以(yi)應對各種挑(tiao)戰的(de)變(bian)頻(pin)器解決方案。西(xi)門子的(de)模塊化(hua)MICROMASTER 430 變頻器就擁有這種靈(ling)活(huo)性。它專門(men)用于工業(ye)領域內的泵和風(feng)機，可(ke)(ke)執行相似應用中的廣(guang)泛任務。與 MICROMASTER 420 相比，這種變頻器能(neng)效(xiao)更高，輸入(ru)與輸出更多，并(bing)且操(cao)作員面板經過(guo)優化，可(ke)(ke)在手動(dong)和自動(dong)操(cao)作模式之間切換(huan)。
