style="text-indent:25px">開關(guān)電源和普通的電源有什么區(qū)別：普通的電源一般是線性電源,線性電源，是指調(diào)整管工作在線性狀態(tài)下的電源.而在開關(guān)電源中則不一樣，開關(guān)管（在開關(guān)電源中，我們一般把調(diào)整管叫做開關(guān)管）是工作在開、關(guān)兩種狀態(tài)下的：開——電阻很??；關(guān)——電阻很大。開關(guān)電源是一種比較新型的電源。它具有效率高，重量輕，可升、降壓，輸出功率大等優(yōu)點。但是由于電路工作在開關(guān)狀態(tài)，所以噪聲比較大。通過下圖，我們來簡單的說說降壓型開關(guān)電源的工作原理。如圖所示，電路由開關(guān)K（實際電路中為三極管或者場效應(yīng)管），續(xù)流二極管D，儲能電感L，濾波電容C等構(gòu)成。當開關(guān)閉合時，電源通過開關(guān)K、電感L給負載供電，并將部分電能儲存在電感L以及電容C中。廣州安防寬溫電源銷售幅電源電壓輸出范圍一般是在85～265VAC的標準。</p><div

（注：如果監(jiān)控距離特別長，需要適當加大電源功率，并且提高電源電壓）。網(wǎng)絡(luò)攝像機電源的配置，較忌諱什么？較忌諱的是：整個監(jiān)控系統(tǒng)共用一個電源。原因如下： 1) 系統(tǒng)維修的時候，經(jīng)常需要打開、關(guān)閉電源。所有的攝像機在打開電源瞬間同時啟動，啟動電流特別大，對電源的沖擊力很大，嚴重的會燒毀電源， 2) 所有的攝像機共用一臺電源，當電源發(fā)生故障時，整個閉路監(jiān)控系統(tǒng)陷入癱瘓。尤其是一些重要出入口的圖像無法監(jiān)視，可能會造成不必要的麻煩。那么正確的做法應(yīng)該是怎樣呢？如上面例子，一個商務(wù)樓有100臺固定攝像機，總共需要約800W的電源，正確的配置應(yīng)該是選擇4臺、每臺200W的電源。這樣，當某一臺電源發(fā)生故障，可以把重要出入口的攝像機接到其它好的電源上，不至于影響整個系統(tǒng)的工作。</p><p

style="text-indent:25px">什么是電源？電源有哪幾類：把其他形式的能轉(zhuǎn)換成電能的裝置叫做電源。發(fā)電機能把機械能轉(zhuǎn)換成電能，干電池能把化學(xué)能轉(zhuǎn)換成電能。發(fā)電機、干電池等叫做電源。通過變壓器和整流器，把交流電變成直流電的裝置叫做整流電源。能提供信號的電子設(shè)備叫做信號源。晶體三極管能把前面送來的信號加以放大，又把放大了的信號傳送到后面的電路中去。晶體三極管對后面的電路來說，也可以看做是信號源。整流電源、信號源有時也叫做電源。.特種電源可細分為：安防電源、高壓電源、醫(yī)療電源、電源、航空航天電源、激光電源、其他特種電源。安防電源怎樣維修安防電源其實跟監(jiān)控電源差不多的。廣州安防寬溫電源銷售</p><p
