style="text-indent:25px">在進(jìn)行充電模塊電源的選擇時(shí)，工程師往往需要進(jìn)行成本、封裝、功率等方面的綜合比較。而生產(chǎn)廠家所提供的模塊電源產(chǎn)品也往往會(huì)為客戶提供幾個(gè)不同范圍的產(chǎn)品以便于挑選，例如商品級(jí)、工業(yè)級(jí)等等，都是比較常見的區(qū)分模式。由于不同的模塊電源溫度等級(jí)不同，制作材料和制造工藝也就不一樣，價(jià)格上的差距很大，一旦選擇不當(dāng)還會(huì)影響使用。因此，對(duì)溫度范圍的把握就顯得至關(guān)重要。為了保證效率，一種比較便捷有效的挑選方式是從溫度范圍出發(fā)，結(jié)合使用功率進(jìn)行綜合比較，可以幫助工程師快速找到比較合適的電源型號(hào)。崇明區(qū)充電電源工廠</p></p><br
