美國(guó)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(hào)說明等技術(shù)問題，還有就是如何選型，每個(gè)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(jià)，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(shí)候貨期延長(zhǎng)了，價(jià)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(huì)12-16周哦，具體還是看的交貨周期哦，一般SEL我們報(bào)價(jià)只是產(chǎn)品本身價(jià)格，硬件價(jià)格，不包含任何技術(shù)服務(wù)費(fèi)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(chǎng)的情況來寫程序?qū)耄拍苁褂茫械腟EL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(tái)接入這款我們不技術(shù)不包括的。
