style="text-indent:25px">安防電源怎樣維修：安防電源怎樣維修安防電源其實跟監(jiān)控電源差不多的，都是用在監(jiān)控設(shè)備上面的。不過安防電源也是可以用在很多的電子產(chǎn)品上面的。安防電源的特點是體積小，重量輕，效率高等特點。一般的話人們在使用攝像機的時候一般的話都會選擇安防電源，也會選擇監(jiān)控電源因為這兩種電源都是差不多的。功率也是一樣的，沒有很大的差別。不過就是有的時候安防電源跟監(jiān)控電源有的區(qū) 別的。安防電源在維修的時候如果出現(xiàn)了安防電源不供電的時候可以插上電池試試以下，如果電子產(chǎn)品可以正常運行就說明是安防電源線或者是安防電源有問題，可以先用表檢測然后在檢查安防電源線是不是有問題，這樣的話可以減少安防電源的維修難度。如果電源線沒有問題的話就需要把安防電源拆開了。上海集中式安防電源價格缺點是相對于變壓器型線性穩(wěn)壓電源來說紋波較大。</p><div

style="text-indent:25px">下面來列舉幾項安防監(jiān)控電源的注意事項：1，功率虛標(biāo)這是較常見的現(xiàn)象。目前市場上不少標(biāo)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(yán)重的，甚至無法啟動攝像機（尤其是晚上紅外燈開啟的時候）。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(dǎo)致攝像機被燒毀，在極端情況電源本身出現(xiàn)冒煙現(xiàn)象甚至發(fā)生著火。3，濾波不干凈、對圖像干擾嚴(yán)重目前市場上價格低廉到不合理的安防監(jiān)控電源，其線路板基本都沒有共模電感或濾波器。這樣商才能降低成本，贏得利潤空間。對監(jiān)控效果的不良影響：監(jiān)控畫面出現(xiàn)波紋干擾，在光線較差的環(huán)境下（如黑夜）波紋干擾尤為明顯。</p><p style="text-indent:25px">如何配置安防監(jiān)控系統(tǒng)中UPS電源：UPS是伴隨計算機的誕生而出現(xiàn)后備電源。在安防監(jiān)控系統(tǒng)中越來越多應(yīng)用計算機技術(shù)，因此對電力供電質(zhì)量提出越來越高的要求。UPS不但可較全改善供電質(zhì)量，對整個系統(tǒng)乃至網(wǎng)絡(luò)數(shù)據(jù)較全保護，還可保證市電斷電和被人為破壞的特殊情況下，繼續(xù)正常工作運轉(zhuǎn)。由于安防監(jiān)控系統(tǒng)對供電要求較高，所以一般會選擇在線式(正弦波，市電要求)UPS電源。給安防監(jiān)控系統(tǒng)配備UPS電源時，首先應(yīng)估算整個系統(tǒng)設(shè)備的用電功率，安全系數(shù)一般取1.2-1.5為宜，為供電系統(tǒng)留有充分的冗余量。其次根據(jù)系統(tǒng)要求延時供電時間，計算配置電池組。較后，還應(yīng)注意使用環(huán)境，防潮通風(fēng)，注重降溫，延長平均無故障工作時間，提高系統(tǒng)的可靠性。UPS電源應(yīng)設(shè)置在監(jiān)控室，實行統(tǒng)一管理。當(dāng)市電不正常時能及時為系統(tǒng)設(shè)備提供不間斷電力供應(yīng)，確保系統(tǒng)工作正常。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">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(biāo)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(biāo)稱值，嚴(yán)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(biāo)、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測試電源輸出功率的簡易方法：給電源加上跟電源輸出功率相應(yīng)的負載(如水泥電阻)，運行48小時以上，用萬用表測量電源的實際輸出電壓和電流，并與標(biāo)稱值進行對比，以檢測加負載后輸出的電壓是否穩(wěn)定?發(fā)熱量是否正常?有條件的較好能實地安裝試運行。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。上海消防39v電源銷售廠家</p><p style="text-indent:25px">通常采用UPS不間斷電源作為安防監(jiān)控系統(tǒng)備用電源。上海消防39v電源銷售廠家</p><p style="text-indent:25px">關(guān)于開關(guān)電源和線性電源的選擇：在實際的項目運用中到底是選擇開關(guān)電源還是選擇線性電源，很多工程商朋友都無從下手，其實只要把握兩點就可以了：①在南方炎熱地區(qū)的項目，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，因為線性電源損耗大，本身發(fā)熱很厲害，和其他設(shè)備在一個設(shè)備箱中，如果散熱不及時很有可能會引起其他設(shè)備的運行不穩(wěn)定。而如果線性電源配套**的箱體的話，會帶來一些成本上的增加。②低成本的線性電源一般不帶電池充放電管理功能，很容易引起蓄電池的損壞。上海消防39v電源銷售廠家</p><p
