class="title">詳細說明</p><div id="h8dfctv" class="box"><p><p style="text-indent:25px">介紹和選購：一、UPS的分類一般情況下，UPS系統(tǒng)分為三大類，為后備式(或離線)、在線互動式和雙轉(zhuǎn)換式(在線)。不同的廠商會提供不同配置的UPS，客戶根據(jù)自己的目標、應用、和功能要求，以及他們的產(chǎn)品差異化的愿望，選擇所需要的UPS。二，蘇州安防寬溫電源廠家、如何購選UPS不間斷電源1、首先要確定您的數(shù)據(jù)中心的設(shè)備是需要的多大功率的，一般來講普通PC機或工控機的功率在200W左右，蘋果機在300W左右，蘇州安防寬溫電源廠家，服務(wù)器在300W與600W之間，其他設(shè)備的功率數(shù)值可以參考該設(shè)備的說明書，蘇州安防寬溫電源廠家。只要按要求購買就可以了。2、其次應了解UPS的額定功率有兩種表示方法：視在功率(單位VA)與實際輸出功率(單位W)，由于無功功率的存在所以造成了這種差別，兩者的換算關(guān)系為：視在功率*功率因數(shù)=實際輸出功率。所以在購買的時候要計算好。如果是在室內(nèi)，可以用好點的帶護套電源線。蘇州安防寬溫電源廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州安防寬溫電源廠家,安防" src="https://tyunfile.71360.com/UploadFile/baoyixinneng/637441725332743848/8050142.png"></div><p style="text-indent:25px">監(jiān)控攝像機電源的選擇還需要注意什么問題：開始：在集中供電方案中給攝像機接電源時，不要把距離較遠的攝像機和距離較近的監(jiān)控攝像機接在同一臺電源上。如果接在同一臺電源上，電源電壓高了，會燒毀近距離的攝像機，電源電壓低了，距離較遠的攝像機無圖像。立方體攝相機采用寬電源設(shè)計，可以在直流輸入電壓12V—36V范圍內(nèi)長期穩(wěn)定工作，徹底根除輸入電壓不穩(wěn)定(如浪涌等)對攝像機造成的危害.可以很好地解決這個問題。是對攝像機集中供電的較佳解決方案。第二：如果監(jiān)控距離太遠，需要配置更高電壓的電源，如30V，36V等等，甚至直接供220V交流電，到前端再變壓。蘇州安防寬溫電源廠家由于電感L的自感，在開關(guān)接通后，電流增大得比較緩慢。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州安防寬溫電源廠家,安防" src="https://tyunfile.71360.com/UploadFile/baoyixinneng/637441725420283124/8321074.png"></div><p style="text-indent:25px">監(jiān)控攝像機電源功率配置的技術(shù)問題：在監(jiān)控攝像機電源的配置方面，也要注意一些細節(jié)，比如不能整個監(jiān)控系統(tǒng)共用一個電源，因為系統(tǒng)維修的時候，經(jīng)常需要打開、關(guān)閉電源。所有的監(jiān)控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。另外一個原因就是所有的監(jiān)控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。正確的辦法可以通過一個例子來說明，如一個商務(wù)樓有100臺固定監(jiān)控攝像機，總共需要約800W的電源，如需采用PoE供電，正確的配置應該是選擇4臺、每臺200W的PoE交換機，這種要求豐潤達16口系列和24口系列PoE交換機都滿足。這樣，當某一臺交換機發(fā)生故障，可以把重要出入口的攝像機接到其它好的交換機上，不至于影響整個系統(tǒng)的工作。</p><p style="text-indent:25px">安防監(jiān)控電源的主要危害包括以下方面：1、功率虛標這是較常見的現(xiàn)象。目前市場上不少標注2A的安防監(jiān)控電源，其實際輸出只有1A左右甚至更低！部分安防監(jiān)控電源因為采用了劣質(zhì)元器件或拆機件等不合格元器件，在使用一段時間后，輸出功率發(fā)生明顯衰減！對攝像機的影響：攝像機的圖像產(chǎn)生抖動、無彩色或無圖像，夜視效果不佳。嚴重的，甚至無法啟動攝像機。這時可在攝像機加載情況，測量電源接口處的電壓值、電流值便可發(fā)現(xiàn)電源的實際輸出數(shù)值。2、保護措施不足不少劣質(zhì)安防監(jiān)控電源，未按正常電源設(shè)計，采用過載過溫保護設(shè)計，甚至省掉保險管。不良影響：導致攝像機被燒毀，在極端情況下，電源會出現(xiàn)冒煙現(xiàn)象甚至發(fā)生著火。檢修簡單，更換電源簡易因為每個攝像機都有自立的安防監(jiān)控電源。</p><div

style="text-indent:25px">鑒于這些選項，您應該如何去選擇您的UPS配置呢：在選擇UPS的時候你需要自己的業(yè)務(wù)需求，同時還要了解自己的財政預算，設(shè)定UPS系統(tǒng)的投入資本和運營成本。你還要了解UPS的可用性，那么您選擇的UPS系統(tǒng)不應該是那些只能夠容忍幾個小時的停機時間。您的UPS配置的選擇應與您的可用性需求相一致，并應根據(jù)數(shù)據(jù)中心停機的潛在損失，設(shè)置您的預算。冷卻基礎(chǔ)設(shè)施，根據(jù)選擇的UPS系統(tǒng)，給您的設(shè)施增加冷負荷。對于大型數(shù)據(jù)中心來說，甚至UPS效率降低一個或兩個百分點都可能轉(zhuǎn)化為大量的熱量，多余的熱量必須去除，以保護設(shè)備。您現(xiàn)有的基礎(chǔ)設(shè)施可以處理這個負荷嗎，或者您的UPS有必要升級嗎?空間，UPS系統(tǒng)占用寶貴的數(shù)據(jù)中心地面空間，所以確保您選擇的配置不會要求在您的設(shè)施中增加更多的空間?，F(xiàn)在的機房可以說是一寸土地一寸金，所以UPS的大小也是格外重要的。由逆變器直接向設(shè)備提供交流電，同時充電器給蓄電池充電，保持蓄電池滿容量。蘇州安防寬溫電源廠家</p><p style="text-indent:25px">如果選擇線性電源，建議不要將線性電源和其他設(shè)備放在同一個設(shè)備箱中。蘇州安防寬溫電源廠家</p><p style="text-indent:25px">自立供電與集中供電如何選擇：自立供電與集中供電模式的優(yōu)缺點大致如上，具體怎么選擇，要視實際安裝環(huán)境及客戶要求而定。一般來說，4路以下的監(jiān)控系統(tǒng)采用自立供電各為合適。 4路到16路的監(jiān)控系統(tǒng)，若距離相當，建議選擇集中供電模式。 16路以上的監(jiān)控，可以采用多路集中供電結(jié)合，前提是必須做好前期配置。舉例子：如果一個商務(wù)樓，有100臺固定型網(wǎng)絡(luò)攝像機，每臺攝像機的額定功率是4W，我們該如何配置攝像機電源呢？根據(jù)上面的計算方法，我們計算出，攝像機的額定功率是4W*100臺=400W，攝像機實際使用的功率400W*1.3=520W。考慮損耗后，攝像機需要的功率是520W*1.3=676W 加上電源余量，攝像機較終需要配置的電源功率是676W*1.3=878W 。蘇州安防寬溫電源廠家</p></p><br /><p>文章來源地址: http://m.cdcfah.com/cp/2931459.html</p></div></div></div></div></div><div id="3wvcta7" class="page-right twoColRt"><div
