style="text-indent:25px">安防監(jiān)控電源好壞選購時(shí)考慮的幾個(gè)要素：1.用途明確，有的放矢電源和安防設(shè)備是配套存在，不同電源輸出功率都不同，工作狀況也不一樣，在選購電源時(shí)，只有針對(duì)自己所使用的范圍有明確的了解，才能選購出正確的電源產(chǎn)品。2.防雨，防浪，防雷擊，散熱功能這一點(diǎn)主要針對(duì)室外監(jiān)控電源而言。大雨，強(qiáng)雷，暴曬——室外充滿各種不可控的氣候因素，而要保證365天不間斷運(yùn)作，電源產(chǎn)品必須有面對(duì)各種情景的應(yīng)變和防護(hù)能力。其中散熱功能與之相對(duì)的是外殼的耐高溫功能，一般外殼耐高溫要達(dá)到60°，現(xiàn)在市場(chǎng)較高是65°。3.品牌電源，質(zhì)量保證品牌是一個(gè)產(chǎn)品的臉面。撐得起一個(gè)面子的品牌，必然是歷史悠久，信譽(yù)度高，能夠長(zhǎng)期為客戶提供品質(zhì)產(chǎn)品和服務(wù)的企業(yè)。因此，選購電源產(chǎn)品時(shí)，較好選擇品質(zhì)好，信譽(yù)有保證的企業(yè)購買。如深圳市小耳朵電源有限公司，XED電源品牌已經(jīng)深入人心，現(xiàn)場(chǎng)也有相應(yīng)的電源測(cè)試儀，對(duì)于電源產(chǎn)品的質(zhì)量，各類參數(shù)，都可以進(jìn)行當(dāng)場(chǎng)測(cè)試。</p><p style="text-indent:25px">UPS(不間斷電源)的工作原理：后備式UPS電源在市電正常供電時(shí)，市電通過交流旁路通道經(jīng)轉(zhuǎn)換開關(guān)直接向負(fù)載提供電源，UPS電源內(nèi)的逆變器處于停止工作狀態(tài)，這時(shí)的UPS電源實(shí)質(zhì)上相當(dāng)于一臺(tái)性能單一的市電穩(wěn)壓器。它除了對(duì)市電電壓的幅度波動(dòng)有所改善外，對(duì)電壓的頻率不穩(wěn)、波形畸變以及從電網(wǎng)侵入的*等不良影響基本上沒有任何改善。只有當(dāng)市電供電中斷或低于170伏時(shí)，蓄電池才立刻對(duì)逆變器供電，向負(fù)載提供穩(wěn)壓、穩(wěn)頻的方波交流電源。正常工作一段時(shí)間，這就需要啟用備用電源來維持這段時(shí)間監(jiān)控系統(tǒng)的正常工作。備用電源有雙路或多路供電、蓄電池組供電、發(fā)電機(jī)供電、UPS供電等等。但通常采用UPS不間斷電源作為安防監(jiān)控系統(tǒng)備用電源。拋錨停擺，整系統(tǒng)癱瘓，造成無可挽回的損失。</p><div

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(jī)能把機(jī)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(jī)、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(hào)的電子設(shè)備叫做信號(hào)源。晶體三極管能把前面送來的信號(hào)加以放大，又把放大了的信號(hào)傳送到后面的電路中去。晶體三極管對(duì)后面的電路來說，也可以看做是信號(hào)源。整流電源、信號(hào)源有時(shí)也叫做電源。.特種電源可細(xì)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。蓄電池經(jīng)常壞，也沒有起到斷電維持系統(tǒng)正常運(yùn)行的能力。濟(jì)南安防系統(tǒng)電源批發(fā)價(jià)格</p><p style="text-indent:25px">是由于它使用的是工頻變壓器，有笨重、體積大的問題存在。蘇州安防系統(tǒng)電源價(jià)格</p><p style="text-indent:25px">自立供電與集中供電如何選擇：需要配置的電源功率=攝像機(jī)的額定功率*1.3*1.3*1.3 （注：如果監(jiān)控距離特別長(zhǎng)，需要適當(dāng)加大電源功率，并且提高電源電壓）。網(wǎng)絡(luò)攝像機(jī)電源的配置，較忌諱什么？較忌諱的是：整個(gè)監(jiān)控系統(tǒng)共用一個(gè)電源。原因如下： 1) 系統(tǒng)維修的時(shí)候，經(jīng)常需要打開、關(guān)閉電源。所有的攝像機(jī)在打開電源瞬間同時(shí)啟動(dòng)，啟動(dòng)電流特別大，對(duì)電源的沖擊力很大，嚴(yán)重的會(huì)燒毀電源， 2) 所有的攝像機(jī)共用一臺(tái)電源，當(dāng)電源發(fā)生故障時(shí)，整個(gè)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(huì)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(gè)商務(wù)樓有100臺(tái)固定攝像機(jī)，總共需要約800W的電源，正確的配置應(yīng)該是選擇4臺(tái)、每臺(tái)200W的電源。這樣，當(dāng)某一臺(tái)電源發(fā)生故障，可以把重要出入口的攝像機(jī)接到其它好的電源上，不至于影響整個(gè)系統(tǒng)的工作。蘇州安防系統(tǒng)電源價(jià)格</p></p><br
