class="title">詳細(xì)說明</p><div id="lkuqvg3" class="box"><p><p> 電源模塊輸出有電壓但電壓低于標(biāo)稱輸出值是測試過程中經(jīng)常遇到的問題，出現(xiàn)這種情況的原因無非有兩種，一是電源模塊為不良品或損壞，二是使用方法問題。下文天磁將重點討論使用方法導(dǎo)致的電源模塊輸出電壓低的情況。<span style="font-size:12px;">輸入電壓偏低是容易被忽略的情況，當(dāng)輸出有問題時我們應(yīng)該檢查輸入是否正常。對于輸入為定壓或?qū)拤旱碾娫茨K，當(dāng)輸入值偏低時將導(dǎo)致輸出值也偏低。當(dāng)然，這種情況是有限度的，對于一個特定的模塊來說，當(dāng)輸入電壓過低時將導(dǎo)致其不能工作，無輸出電壓。</span><span style="font-size:12px;">輸出過載是指負(fù)載工作功率大于電源模塊的額定輸出功率，過載情況下電源模塊的輸出電壓明顯被拉低。以ZY0505FS-1W為例，當(dāng)負(fù)載電流增大到300mA時，輸出電壓只有4，北京智慧燈桿電-源哪個品牌性能好.5V。持續(xù)過載將影響到電源模塊的工作效率、穩(wěn)定性以及散熱情況，導(dǎo)致模塊使用壽命減少。若是過載導(dǎo)致的輸出電壓過低，則需要提升電源模塊的輸出功率，北京智慧燈桿電-源哪個品牌性能好，可以選擇2W或3W的模塊，北京智慧燈桿電-源哪個品牌性能好。</span>

style="font-size:12px;">從隔離的目的來說，可以將隔離分為安全隔離和噪聲隔離兩大類。由于嵌入式系統(tǒng)的應(yīng)用廣</span><span style="font-size:12px;">，在硬件設(shè)計中，經(jīng)常會遇到多電壓供電，數(shù)模混合，高速低速信號同板等復(fù)雜的情況，處理稍有不慎，就會引入干擾，輕則降低產(chǎn)品性能，重則干擾通信甚至引起系統(tǒng)重啟、癱瘓等。此時，隔離就顯得尤為重要，在嵌入式系統(tǒng)的設(shè)計中，一般都會選擇使用隔離電源模塊對PCB不同區(qū)塊進(jìn)行隔離供電，從比較大限度上減少噪聲干擾，提高系統(tǒng)穩(wěn)定性。</span> </p> <p> <br /> 江蘇電-源廠家供應(yīng)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: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京智慧燈桿電-源哪個品牌性能好,電-源"

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)計上已有必要的應(yīng)對防護(hù)性設(shè)計措施，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說明，以便廠家出廠時的電源模塊內(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 /> </p><p> 便捷方式。一種常規(guī)的恒流限壓定時充電工作方式，此方式工作時，充電機(jī)以設(shè)定電流向負(fù)載電瓶恒流充電，當(dāng)充電電壓達(dá)到限<span style="font-size:12px;">制電壓時，電壓不再上升，而充電電流逐漸減小。當(dāng)充電時間達(dá)到設(shè)定時間時，充電機(jī)自動結(jié)束充電過程。此種模式充電，電流不宜</span><span style="font-size:12px;">超過100 A，否則電瓶不易充滿，且析氣量大。</span><span style="font-size:12px;">智能方式。一種針對不同規(guī)格型號的電池采取不同整定參數(shù)充電的工作方式。而對每一種電池又有三種充電模式，即初充模式、</span><span style="font-size:12px;">恒流模式和快速模式。</span> </p> <p> <p> <br /> </p> 我們平時用的充電器或電池等供電裝置到底是不是電源呢？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京智慧燈桿電-源哪個品牌性能好,電-源"

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，戶外通信基站，高壓電力等，對電源模塊的隔離度要求則更高。</span>
