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，市電通過交流旁路通道經(jīng)轉(zhuǎn)換開關(guān)直接向負載提供電源，UPS電源內(nèi)的逆變器處于停止工作狀態(tài)，這時的UPS電源實質(zhì)上相當于一臺性能單一的市電穩(wěn)壓器。它除了對市電電壓的幅度波動有所改善外，對電壓的頻率不穩(wěn)，成都安防集中供電電源報價、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。只有當市電供電中斷或低于170伏時，蓄電池才立刻對逆變器供電，成都安防集中供電電源報價，向負載提供穩(wěn)壓、穩(wěn)頻的方波交流電源。正常工作一段時間，這就需要啟用備用電源來維持這段時間監(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，成都安防集中供電電源報價、發(fā)電機供電、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。普通電源：普通電源電壓輸出范圍一般是在180V-240V的標準。成都安防集中供電電源報價</p><div

style="text-indent:25px">電源在門禁報警系統(tǒng)的應(yīng)用及選擇：1、有效的防雷保護產(chǎn)品是否有防雷保護的判斷：①目測電源上是否有保護電路的設(shè)計。（此方法適合對電路硬件有研究人士）。②了解廠家在防雷的技術(shù)上面是否有技術(shù)的積累，如產(chǎn)品可靠性的實際演示。相關(guān)產(chǎn)品的防雷檢測報告等等。2、寬溫度適應(yīng)范圍溫度適應(yīng)范圍在-40度~85度之內(nèi)，就可以滿足要求了。具體的測試方法可以要求廠家配合提供，或者在質(zhì)保上能在合同條款明確以保證自己的合法權(quán)益。3、對后備電池智能充放電管理電源的充放電管理功能，主要是避免蓄電池過充而損壞蓄電池，也不會因為過度放電后重新充電，出現(xiàn)因充電電流過大而拉低其他設(shè)備的電流供應(yīng)，造成系統(tǒng)不穩(wěn)定的情況。成都安防集中供電電源報價檢修簡單，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">安防監(jiān)控電源的主要危害包括以下方面：1.電源外殼采用劣質(zhì)塑料電源外殼為電源重要保護，避免外力損壞電源或發(fā)生觸電事故。部分不良商家生產(chǎn)安防監(jiān)控所用的便宜劣質(zhì)塑料外殼，在使用較長時間后或放在戶外環(huán)境使用，會發(fā)生變色、外殼開裂現(xiàn)象。危害：假若電源進水，輕則損壞電源，重則燒壞監(jiān)控攝像頭，甚至發(fā)生觸電事故，傷及人身安全。選用劣質(zhì)電源，存在各種潛在的不必要風險故障。部分劣質(zhì)電源在前期使用并未出現(xiàn)明顯問題，但在使用一段時期后容易出現(xiàn)各種故障，給監(jiān)控系統(tǒng)帶來以上所述的傷害，給選購者帶來不必要的經(jīng)濟損失或聲譽損失。即使部分不良商家提供保修、包換服務(wù)，但其質(zhì)保服務(wù)對象很少于電源，對于劣質(zhì)電源所造成的附帶經(jīng)濟損失（如燒壞監(jiān)控攝像頭等），則不承擔任何責任。因此，建議各位選購安防監(jiān)控電源時，一定要擦亮眼睛，別被低價蒙騙，一定要看清選購的安防監(jiān)控電源的電路設(shè)計、用料質(zhì)量。</p><p style="text-indent:25px">集中供電的缺點：1、前期配置復(fù)雜監(jiān)控攝像機在啟動瞬間需要很大的啟動電源，而且遠距離的電力輸送會產(chǎn)生損耗，因此集中供電的功率并非是所有監(jiān)控攝像機的功率相加。采取集中供電模式，需要工程師對整個監(jiān)控系統(tǒng)有詳盡了解，以便做出合理方案。（實際上，由于攝像機在啟動瞬間，啟動電流很大，再加上工程上遠距離傳輸?shù)膿p耗，所以，監(jiān)控攝像機需要的電源，不是簡單地把所有攝像機的額定功率相加。正確的做法是把整個監(jiān)控系統(tǒng)的攝像機的額定功率相加再乘以1.3倍，這個是攝像機實際需要的功率，然后再加上約30%的損耗；較后再加上30%的余量，作為將來擴容使用。） 2、存在出現(xiàn)監(jiān)控系統(tǒng)癱瘓現(xiàn)象的可能性沒有采用UPS電源的集中供電模式下的供電系統(tǒng)一旦出現(xiàn)問題，將會導(dǎo)致整個監(jiān)控系統(tǒng)無法正常工作，陷入癱瘓狀態(tài)。對POE受電設(shè)備的要求是必須同時支持兩種供電方式。</p><div style="width:100%;text-align:

style="text-indent:25px">電源在視頻門禁報警系統(tǒng)的應(yīng)用及選擇 1. 測量電源實際輸出功率視頻門禁報警系統(tǒng)中涉及到要供電的設(shè)備非常繁多，為保證各設(shè)備都能正常穩(wěn)定運行，電源需要有足夠的電量給各設(shè)備供電。選購電源時，要特別注意電源的標稱值，而且對于實際參數(shù)較好實地進行測試，因為市面上有一些價格低廉的門禁電源在實際應(yīng)用中往往達不到標稱值，嚴重影響了視頻門禁報警系統(tǒng)的正常穩(wěn)定運行。建議選購電源時選擇技術(shù)參數(shù)達標、質(zhì)量可靠、信譽好、適用于視頻門禁報警系統(tǒng)的電源廠家。目前有些視頻門禁的廠家，電源是搭配和控制器一起銷售的，通常來說這類廠家對于電源選擇是考慮了項目的實際應(yīng)用情況的，對于系統(tǒng)整體的質(zhì)量也有更好的保障.安防電源怎樣維修安防電源其實跟監(jiān)控電源差不多的。成都安防集中供電電源報價</p><p style="text-indent:25px">缺點是相對于變壓器型線性穩(wěn)壓電源來說紋波較大。成都安防集中供電電源報價</p><p style="text-indent:25px">UPS(不間斷電源)的工作原理：在線式UPS電源在市電正常供電時，它首先將市電交流電源經(jīng)整流變成直流電源，然后進行脈寬調(diào)制、濾波、并將直流電源經(jīng)逆變器重新轉(zhuǎn)換成正弦波交流電源向負載供電，一旦市電中斷，立即改由蓄電池提供的直流經(jīng)逆變器、電脈寬調(diào)制、濾波，向負載提供正弦波交流電源。因此，對在線式UPS而言，在正常情況下，無論有無市電，它都是由UPS電源的逆變器對負載供電，這樣就避免了所有由市電電網(wǎng)電壓波動及而帶來的影響。顯而易見，在線式UPS電源的供電質(zhì)量明顯優(yōu)于后備式UPS電源，因為它可以實現(xiàn)對負載的穩(wěn)頻、穩(wěn)壓供電。而且在由市電轉(zhuǎn)換到蓄電池供電時，其轉(zhuǎn)換時間基本為零，真正給用戶提供高質(zhì)量穩(wěn)壓、穩(wěn)頻的純凈正弦波電源，從而提供符合安防監(jiān)控系統(tǒng)需要的電源保護。在線互動式UPS電源結(jié)合了后備式UPS和在線式UPS的許多優(yōu)點，也是一種很不錯的變換形式，但是由于它使用的是工頻變壓器，有笨重、體積大的問題存在。成都安防集中供電電源報價</p></p><br
