模塊在使用時(shi)，負載為動(dong)態負載，使得模塊輸(shu)出電(dian)壓(ya)峰(feng)峰(feng)值變(bian)大，但注(zhu)意這不是紋波噪(zao)聲。

當負(fu)(fu)載(zai)(zai)電(dian)(dian)流如(ru)果進行(xing)周(zhou)(zhou)期性(xing)突(tu)變(bian)時，模(mo)塊(kuai)輸出(chu)電(dian)(dian)壓的峰(feng)峰(feng)值(zhi)會(hui)變(bian)大。這(zhe)是一(yi)個瞬態量(liang)，但有時會(hui)被(bei)誤以為是紋波(bo)噪聲。所以當使(shi)用一(yi)個電(dian)(dian)源模(mo)塊(kuai)給多(duo)個電(dian)(dian)路(lu)單(dan)元(yuan)供(gong)電(dian)(dian)時，對于(yu)有周(zhou)(zhou)期性(xing)負(fu)(fu)載(zai)(zai)變(bian)化(hua)的電(dian)(dian)路(lu)，前級(ji)需(xu)要增加π型濾波(bo)，減小這(zhe)部(bu)分(fen)電(dian)(dian)路(lu)的瞬態變(bian)化(hua)對其他電(dian)(dian)路(lu)的干擾。

關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)直(zhi)流輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)為46.4V，使電(dian)(dian)(dian)(dian)池(chi)組直(zhi)接(jie)對實際負(fu)荷進行(xing)放(fang)電(dian)(dian)(dian)(dian)至開關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)直(zhi)流輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)保護設置值。由于(yu)電(dian)(dian)(dian)(dian)池(chi)組放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流大(da)，應按電(dian)(dian)(dian)(dian)源(yuan)(yuan)維護規(gui)程(cheng)考慮48V供電(dian)(dian)(dian)(dian)范(fan)圍40～57V的(de)低(di)供電(dian)(dian)(dian)(dian)低(di)壓(ya)(ya)門(men)限，電(dian)(dian)(dian)(dian)池(chi)組至設備供電(dian)(dian)(dian)(dian)回路全程(cheng)壓(ya)(ya)降(jiang)3.2V及電(dian)(dian)(dian)(dian)池(chi)單體放(fang)電(dian)(dian)(dian)(dian)低(di)1.8V的(de)要求(qiu)考慮。

為了保證供(gong)電(dian)系(xi)統安全，所以帶實際負載的放電(dian)電(dian)流和放電(dian)時(shi)間掌控較困難，對(dui)(dui)電(dian)池(chi)組容量評估不(bu)夠準(zhun)確，對(dui)(dui)電(dian)池(chi)性能測(ce)試(shi)存在不(bu)確定因素，尤其(qi)對(dui)(dui)使用3年以上電(dian)池(chi)組性能檢測(ce)難以達(da)到(dao)試(shi)驗的預期效果。
