class="title">詳細(xì)說明</p><div id="rzqhouq" class="box"><p><p> 隔離電壓，是隔離型DC/DC電源模塊的一個重要指標(biāo)，一般分1000VDC、1500VDC、2000VDC、3000VDC、6000VDC等規(guī)格，是指在一定時(shí)間內(nèi)（通常是1秒）電源模塊所能承受的、施加在輸入端和輸出端之間的比較高電壓。隔離電壓等級越高，電源模塊內(nèi)部的保護(hù)器件和設(shè)計(jì)工藝要求就越高，從根本上講，就是成本越高。那么怎樣選擇合適的隔離電壓呢？<span style="font-size:12px;">電源模塊的隔離電壓，需要根據(jù)應(yīng)用場合來選擇。一般場合使用對電源模塊隔離電壓要求不是很高，但是更高的隔離電壓可以保證模塊電源具有更小的漏電流，更高的安全性和可靠性，并且EMC特性也更好一些，加之嵌入式系統(tǒng)器件集成度高，封裝小，相對比較脆弱，因此一般應(yīng)用業(yè)界，普遍的隔離電壓水平為1500VDC或以上。但在一些特殊的行業(yè)，比如醫(yī)療，北京智慧電-源***選擇，戶外通信基站，高壓電力等，北京智慧電-源***選擇，對電源模塊的隔離度要求則更高，北京智慧電-源***選擇。</span>

另一個是要根據(jù)負(fù)載的波動情況來確定，有的負(fù)載較穩(wěn)定，有的負(fù)載就波動較大，甚至于有的還會有空載、或滿載、或瞬間負(fù)載變大、或瞬間負(fù)載跌落的情況發(fā)生，若有這種問題，比較好與電源模塊廠家說明，確認(rèn)其設(shè)計(jì)上已有必要的應(yīng)對防護(hù)性設(shè)計(jì)措施，不是所有的電源都可以達(dá)到這個目標(biāo)的。<span style="font-size:12px;">負(fù)載的類型也是一個影響因素。一般的模塊，其輸出是按照默認(rèn)為阻性負(fù)載而設(shè)計(jì)的，如果負(fù)載是感性或容性負(fù)載，都需要與模塊廠家單獨(dú)說明，以便廠家出廠時(shí)的電源模塊內(nèi)部器件或參數(shù)稍作調(diào)整。</span><span style="font-size:12px;">電源模塊的開關(guān)頻率也是需要關(guān)注的，他決定了外接電源濾波器濾波參數(shù)（截止頻率、階次）的選擇。</span> </p> <p> <br /> 浙江智能路燈電-源哪個品牌性能好智能電源具備良好的性能與溫度控制技術(shù)。</p><div style="width:100%;text-align:

磁珠、電容、二極管、電阻…都具有類似的潛規(guī)則，只是我們不太注意而已。電源模塊的拓?fù)浣Y(jié)構(gòu)有多種，反激、正激、推挽、半橋、全橋多種，每種因?yàn)槠湓淼牟煌?，也表現(xiàn)為在某些特性指標(biāo)方面的優(yōu)越性。反激電源在開關(guān)的一個周期中，充電的時(shí)段沒有放電，就是因?yàn)檫@個特性，其時(shí)間響應(yīng)特性、紋波特性就很難做到很好，雖然可以通過大的儲能電容協(xié)助解決一點(diǎn)，但原理性缺點(diǎn)終歸是硬傷。漏感也大等等問題，但其優(yōu)點(diǎn)是電路簡單，成本低，體積小，不必加磁復(fù)位繞組，而且輸入電壓范圍比較寬。也正因?yàn)榇?，才有了其占總電源市?成以上的份額。 </p> <p> <br /> </p><p> 走線阻抗大。電源模塊輸出與負(fù)載連接必然要有一段PCB走線，走線越長、走線越窄則它的等效電阻越大。等效電阻可以認(rèn)為是串聯(lián)在負(fù)載的工作回路中，將起到分壓作用，因此導(dǎo)致負(fù)載兩端的電壓小于模塊的輸出電壓。此外，除了走線問題還有很多情況起到類似的作用，比如焊點(diǎn)接觸不良導(dǎo)致等效電阻增加，線路氧化或腐蝕導(dǎo)致等效電阻增加。<span style="font-size:12px;">防反接二極管。很多產(chǎn)品的AC和DC部分是不在一塊板上的，在生產(chǎn)或終端客戶使用中不可避免涉及到插拔電源連接器的情況。為防止此過程中的反接導(dǎo)致的硬件損壞，常串入一只二極管解決。以壓降0.7V的二極管為例，b1 b2間的電壓將比a1 a2間電壓小0.7V，這也就是上面所討論的輸入電壓偏低的情況，可以通過選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。</span> </p> <p> 帶RS485與以太網(wǎng)通信。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
