1.可以降低電機(jī)的啟動(dòng)電流，從而減少電容量。 2.減少啟動(dòng)應(yīng)力，可以延長(zhǎng)電動(dòng)氣以及其他的相關(guān)設(shè)備的使用壽命，維修率低。 3.平穩(wěn)的啟動(dòng)和軟停車，都是避免了傳統(tǒng)的啟動(dòng)設(shè)備的喘振問(wèn)題等。 4.完善可靠的保護(hù)功能，能夠有效的保護(hù)電機(jī)以及設(shè)備的安全。 5.同時(shí)還能有效的升降起動(dòng)電流以及配電電容量。 6.多種起動(dòng)模式及寬范圍的電流、電壓等設(shè)定，可適應(yīng)多種負(fù)載情況；淄博科恩軟啟動(dòng)器價(jià)格行情</p><p
