美國SEL-787變壓器SEL078721E2C6XCCA681A810選型指南
HYLIK海歷克張濤張經(jīng)理今天給大家?guī)淼氖顷P(guān)于SEL787系列變壓器選型資料,以及型號說明等技術(shù)問題,還有就是如何選型,每個字母代表的意思,全部在下面哦,近期芯片斷供導(dǎo)致跟芯片有關(guān)的產(chǎn)品訂貨周期都延遲交貨,以及漲價,有的品牌漲幅在15%左右,所以有需要訂貨的客戶,建議盡快下單哦,不然到時候貨期延長了,價格也漲了,正常SEL訂貨周期8-12周的,要是延遲交貨可能貨期會12-16周哦,具體還是看廠家的交貨周期哦,一般SEL我們報價只是產(chǎn)品本身價格,硬件價格,不包含任何技術(shù)服務(wù)費用哦,就像買電腦一樣的,電腦只是硬件,但是SEL品牌不同的是,還需要導(dǎo)入軟件才能用,軟件需要根據(jù)現(xiàn)場的情況來寫程序?qū)?,才能使用,有的SEL還需要連接系統(tǒng)才能用,系統(tǒng)不是SEL品牌的,是別的品牌的系統(tǒng)后臺接入這款我們不技術(shù)不包括的。
