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備非常繁多，為保證各設備都能正常穩(wěn)定運行，電源需要有足夠的電量給各設備供電。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用中往往達不到標稱值，濟南安防**穩(wěn)壓電源生產廠家，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參數(shù)達標、質量可靠，濟南安防**穩(wěn)壓電源生產廠家，濟南安防**穩(wěn)壓電源生產廠家、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用情況的，對于系統(tǒng)整體的質量也有更好的保障.濾波效率大為提高,濾波電容的容量和體積大為減小。濟南安防**穩(wěn)壓電源生產廠家</p><div

style="text-indent:25px">如何配置安防監(jiān)控系統(tǒng)的UPS電源：UPS電源是為安防監(jiān)控系統(tǒng)提供動力的中心部分，是為安防監(jiān)控系統(tǒng)提供持續(xù)、穩(wěn)定、不間斷電力供應的重要外部設備。目前，市場上供應的UPS電源設備種類繁多，輸出功率也有所不同。UPS電源按工作模式可分為后備式、在線式兩大類。按其輸出波形又分為方波輸出和正弦波輸出兩種。以下主要介紹了UPS電源的工作原理，以及如何配置安防監(jiān)控系統(tǒng)的UPS電源。備用電源是安防監(jiān)控系統(tǒng)基本要素之一。缺少備用電源的系統(tǒng)則暗藏致命缺陷，不能投入實際應用當中，因為極可能在關鍵時刻貽誤戰(zhàn)機，拋錨停擺，整系統(tǒng)癱瘓，造成無可挽回的損失。青島安防集中電源避免出現(xiàn)監(jiān)控系統(tǒng)癱瘓現(xiàn)象用UPS，將會導致整個監(jiān)控系統(tǒng)無法正常工作，陷入癱瘓狀態(tài)。</p><div

style="text-indent:25px">開關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，是指調整管工作在線性狀態(tài)下的電源.而在開關電源中則不一樣，開關管（在開關電源中，我們一般把調整管叫做開關管）是工作在開、關兩種狀態(tài)下的：開——電阻很??；關——電阻很大。開關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電源的工作原理。如圖所示，電路由開關K（實際電路中為三極管或者場效應管），續(xù)流二極管D，儲能電感L，濾波電容C等構成。當開關閉合時，電源通過開關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。</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)、在線互動式和雙轉換式(在線)。不同的廠商會提供不同配置的UPS，客戶根據自己的目標、應用、和功能要求，以及他們的產品差異化的愿望，選擇所需要的UPS。二、如何購選UPS不間斷電源1、首先要確定您的數(shù)據中心的設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，服務器在300W與600W之間，其他設備的功率數(shù)值可以參考該設備的說明書。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。如果監(jiān)控距離太遠，需要配置更高電壓的電源。</p><div

style="text-indent:25px">選擇智能門禁電源時應該注意什么：視頻門禁報警系統(tǒng)簡介視頻門禁項目伴隨著社會管理創(chuàng)新的進步，對于人口尤其是流動人口的管理起到不可替代的作用，目前全國各地對于視頻門禁的建設都在如火如荼的進行，已經在安防行業(yè)中形成了一種新的市場力量。為了適應市場的需求，目前無論是門禁系統(tǒng)的供應商、還是視頻系統(tǒng)的供應商，包括配套的光端機、電源等等的供應商都在根據視頻門禁市場的特定需求在優(yōu)化自己的產品方案以使自己的能在市場競爭中能更具有競爭力。本文主要是針對視頻門禁應用場合的特點，結合自己的實際視頻門禁工程經驗，分享在實際的項目選型中，對于視頻門禁電源的選擇應該注意的幾個問題。請選擇AC24V的電源，因為同樣的傳輸距離，電壓越高，損耗越小，線的成本也越小。深圳安防系統(tǒng)電源生產廠家</p><p

style="text-indent:25px">對后備電池智能充放電管理：因出租屋或小區(qū)的特殊環(huán)境，市電停電時有發(fā)生，而視頻門禁尤其是中間的門禁是對老百姓的生活有直接聯(lián)系的，要求任何時候都要能正常運行，所以一般各地建設視頻門禁的規(guī)范中對于后備電池的續(xù)航時間都會提具體要求，一般要求斷電后能維持系統(tǒng)正常運行4——6小時以上，電源具備充放電管理功能。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備的電流供應，造成系統(tǒng)不穩(wěn)定的情況。補充：相比門禁而言，視頻系統(tǒng)的功耗比較大，而且并不影響直接的開關門，所以在實際建設的時候對于斷電后的電源供應，很多工程商選擇斷電后優(yōu)先保證門禁的電源供應。目前有的電源產品已經具備了市電斷電檢測功能，斷電后聯(lián)動切斷視頻系統(tǒng)的電源供應，從而確保用盡可能小的蓄電池來確保門禁系統(tǒng)更長供電續(xù)航時間，實實在在的節(jié)約工程商在后備電池上的建設投資。濟南安防**穩(wěn)壓電源生產廠家</p></p><br
