變頻器原理

由驅動(dong)系統執行的(de)每個任務都(dou)具有自身的(de)特(te)定要(yao)求。因此，需要(yao)提供(gong)可方便而靈活地加以調整(zheng)以應對(dui)各種挑戰的(de)變頻器解決方案(an)。西門子的(de)模塊化MICROMASTER 430 變頻器就擁有這種(zhong)靈活性。它專門用于(yu)工業領域內的(de)(de)泵和(he)(he)風機，可執行相(xiang)似應用中的(de)(de)廣泛(fan)任(ren)務。與 MICROMASTER 420 相(xiang)比，這種(zhong)變頻器能(neng)效(xiao)更高，輸入與輸出更多，并且操作(zuo)員面板經過優化，可在手動和(he)(he)自動操作(zuo)模式之間切換。
