一、開關電源和通信電源的區別在哪里

1、開關電(dian)源是一(yi)種(zhong)用于電(dian)壓轉(zhuan)換(huan)的(de)高頻震蕩電(dian)子電(dian)路，主要的(de)工作(zuo)內(nei)容是：升壓或(huo)降壓，直(zhi)流電(dian)轉(zhuan)換(huan)為交(jiao)流電(dian)，或(huo)交(jiao)流電(dian)轉(zhuan)換(huan)為直(zhi)流電(dian)。

2、通(tong)信電(dian)(dian)(dian)(dian)源(yuan)是(shi)指通(tong)信設備的電(dian)(dian)(dian)(dian)源(yuan)。可以是(shi)蓄電(dian)(dian)(dian)(dian)池(chi)、220V交流(liu)電(dian)(dian)(dian)(dian)、發電(dian)(dian)(dian)(dian)機、干(gan)(gan)電(dian)(dian)(dian)(dian)池(chi)、手機電(dian)(dian)(dian)(dian)池(chi)等(deng)等(deng)，由(you)于是(shi)用于通(tong)信設備，所以一般都要經過高頻震蕩電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)路（開(kai)關電(dian)(dian)(dian)(dian)源(yuan)）而獲得更(geng)穩定、更(geng)精確(que)、干(gan)(gan)擾更(geng)小的電(dian)(dian)(dian)(dian)壓，才(cai)供給通(tong)信設備使用。

綜上，開關電源和通信(xin)電(dian)(dian)源的區別主要體現(xian)在用(yong)途不同(tong)，此外通信(xin)電(dian)(dian)源電(dian)(dian)壓更穩定、更精確、干(gan)擾更小。

二、通信電源多少錢一個

前文已經簡單(dan)了解到了開關電源和通(tong)信電源的區別在(zai)哪里，那么通(tong)信電源多少錢一個呢？

目(mu)(mu)前(qian)市面中，通信電(dian)源(yuan)的價格在1000-5000元/個之間，具體(ti)的價格和品牌有(you)直(zhi)接的關系(xi)，在選購的時候，確定在系(xi)統運行(xing)(xing)的電(dian)壓(ya)下需要多少電(dian)流，在目(mu)(mu)錄或網站上找到可(ke)以提供該電(dian)壓(ya)和電(dian)流的型號，然(ran)后再(zai)進行(xing)(xing)購買。

三、通信電源選購注意事項有哪些

其(qi)實，事(shi)情沒那么簡(jian)單。在(zai)選(xuan)擇(ze)和使用通(tong)信電源時，您還需要考慮許多(duo)其(qi)他事(shi)項(xiang)。以下是工程師在(zai)為其(qi)項(xiang)目選(xuan)擇(ze)和使用電源時常犯的(de)兩個錯誤：

1、沒有購買輸出功率足夠的通信電源。雖然(ran)(ran)您當(dang)然(ran)(ran)不(bu)想購(gou)(gou)買功(gong)率輸出(chu)過多的電(dian)(dian)源(yuan)(yuan)，但試圖通過購(gou)(gou)買功(gong)率輸出(chu)剛好(hao)足夠(gou)的電(dian)(dian)源(yuan)(yuan)來省(sheng)錢也不(bu)是一個(ge)好(hao)主意。如果您以(yi)后必(bi)須用大(da)功(gong)率電(dian)(dian)源(yuan)(yuan)替換它，那么購(gou)(gou)買小(xiao)尺寸電(dian)(dian)源(yuan)(yuan)不(bu)會為您省(sheng)錢。為避免(mian)這種情況，請考慮未來和當(dang)前(qian)的需求(qiu)，并購(gou)(gou)買容量至少高于當(dang)前(qian)需求(qiu)25%的電(dian)(dian)源(yuan)(yuan)。

2、沒有購買輸出電流足夠的通信電源。盡管電(dian)源可能能夠(gou)提(ti)(ti)供(gong)(gong)一定量的(de)(de)功率，但并不(bu)是說它可以提(ti)(ti)供(gong)(gong)每種電(dian)壓/電(dian)流組(zu)合。例如，具(ju)有(you)400VDC范圍的(de)(de)1500W直流電(dian)源可能只能在整(zheng)個范圍內提(ti)(ti)供(gong)(gong)3.75A的(de)(de)最大值。
