許多消費(fèi)者電池用了不到半年的時(shí)間，就出現(xiàn)了問題，***個(gè)想到的就是電池出現(xiàn)了問題，但是許多消費(fèi)者沒有考慮到，劣質(zhì)的電源適配器或非原創(chuàng)電源適配器也會(huì)導(dǎo)致電池壽命降低。 </p> <p> 那么市面上不合規(guī)的充電器到底與合規(guī)的充電器有什么不同呢？ </p> <p> 一、在我們使用的正規(guī)廠家生產(chǎn)的充電器，會(huì)有一個(gè)熔電器裝置，當(dāng)電流過載時(shí)或電池充滿電后，就會(huì)自動(dòng)熔斷，來保證電池不被過大電流造成短路。而劣質(zhì)的充電器，在電池充滿后會(huì)繼續(xù)給電池充電，長(zhǎng)時(shí)間使用這種方式充電，易造成電電池壽命縮短，嚴(yán)重還容易引起火災(zāi)。 </p> <p> 二、正版合格的充電器，在電池充滿電后，會(huì)進(jìn)入進(jìn)入一段時(shí)間的浮充，以保持電池充滿。但是受到價(jià)格的影響，一般劣質(zhì)的充電器不會(huì)有這種功能，導(dǎo)致電池充不滿，影響行駛里程。 </p> <p> 三、由于劣質(zhì)充電器，生產(chǎn)價(jià)格都是比較便宜，完全不考慮安全隱患問題，所以在防火性能上根本不會(huì)考慮，尤其在夏季高溫時(shí)，極易出現(xiàn)短路、過熱，嚴(yán)重還容易引發(fā)自燃，甚至出現(xiàn)大面積火災(zāi)。 </p> <p> 所以在日常使用充電器給電池充電時(shí)，優(yōu)先是原裝充電器，一個(gè)好的充電器才幾十元，比起幾百塊的電池，廣東12v2a電源適配器，廣東12v2a電源適配器，廣東12v2a電源適配器，簡(jiǎn)直是超值，所以在購買充電器時(shí)一定要選擇質(zhì)量電源適配器。新賽的電源我們歡迎您來廠親自參觀，我們也會(huì)用**的電源適配器產(chǎn)品與服務(wù)來回報(bào)您的信任！廣東12v2a電源適配器</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣東12v2a電源適配器,電源適配器" src="https://tyunfile.71360.com/UploadFile/szxskj/637365550533505860/9475716.png"></div><p> 一個(gè)電源適配器的參數(shù)是：12V/1.25A你知道是什么意思嗎？這表示電壓輸出12V，zui大輸出電流1.25A（并不是指實(shí)際使用電流），功率等于電壓乘電流，zui大功率是15W。 </p> <p> 實(shí)際使用中，電源的輸出電流是根據(jù)用電設(shè)備而不同。電源是否合適用，首要看電源電壓，其次zui.大電流要足夠大。 </p> <p> 比如我們常用的BBS無線麥克風(fēng)電源是12V1.25A，一般來講，電壓可以有少許誤差，10V到15V都可以使用——電路主板上都會(huì)有穩(wěn)壓電路，而這個(gè)穩(wěn)壓電路是允許在一定的電壓范圍工作。但是電源的zui.大輸出電流zui.好達(dá)到我們?cè)O(shè)備的額定耗電電流的三倍以上。 </p> <p> 電源的好壞對(duì)于音頻信號(hào)放大輸出有很大影響。在滿足電壓輸出大小的情況下，如果電流過小，在進(jìn)行大動(dòng)態(tài)信號(hào)的放大時(shí)，可能會(huì)導(dǎo)致電源電壓被拉低（甚至?xí)?dǎo)致電源變壓器斷電保護(hù)），然后聲音信號(hào)輸出失真破音（尤其是高音），嚴(yán)重的會(huì)導(dǎo)致后級(jí)設(shè)備燒毀。 </p> <p> 另外，電源對(duì)音色也會(huì)有影響，比如使用線性電源（變壓器直接將220V變到低壓）和使用開關(guān)電源呈現(xiàn)出來的聲音在力度和聲音細(xì)膩度上會(huì)有差異。所以一旦原裝的電源變壓器損壞，臨時(shí)可以用其他同規(guī)格變壓器頂上，但是如果要還原設(shè)備原來的聲音特性，還是要換回原裝電源。 </p> <p> <br />

一款電源適配器的開發(fā)設(shè)計(jì)到使用，不僅得考慮外形是否美觀，工程師還得考慮開關(guān)電源適配器構(gòu)造的合理性，在工作過程中，還得嚴(yán)格控制其溫升范圍值，以免出現(xiàn)溫度過高導(dǎo)致開關(guān)電源適配器的工作效率下降。 </p> <p> 在開關(guān)電源適配器使用過程中，電源產(chǎn)品溫度過高主要有兩個(gè)方面，其一是MOS管，其二是電源器本身設(shè)計(jì)問題，那么接下來我們就從這兩點(diǎn)分析，看如何來解決開關(guān)電源適配器的溫升問題。 </p> <p> 首先我們從MOS管來分析，一般在開關(guān)電源設(shè)計(jì)過程中，MOS管發(fā)熱情況較為嚴(yán)重，因?yàn)橛袚p耗，而MOS管的損耗主要有兩點(diǎn)，一是通態(tài)損耗，二是開關(guān)過程損耗，開關(guān)過程損耗是因?yàn)闁烹姾纱笮〖伴_關(guān)時(shí)間所引發(fā)的，那么該如何去解決呢?我們可以用速度更快、恢復(fù)時(shí)間更短的電子元器件來減小開關(guān)過程的損耗。至于通態(tài)損耗的問題，我們可以用底通態(tài)電阻開關(guān)來減小其損耗的。當(dāng)然更好的設(shè)計(jì)也能減小損耗的，這個(gè)就看工程師的水平了。 </p> <p> 其次，我們分析到了變壓器本身的問題，一般導(dǎo)致變壓器出現(xiàn)高溫發(fā)燙的情況主要有四點(diǎn)，1.繞線工藝的問題2.銅損3.變壓器鐵損4.變壓器功率太小，我們可以從這四點(diǎn)來解決。除了這幾種情況以外，其實(shí)還有一種可能性，那就是變壓器出現(xiàn)了老化現(xiàn)象。 </p> <p> <br /> </p> <p> <br /> </p><p> 什么是電源適配器？ </p> <p> 電源適配器是小型便攜式電子設(shè)備及電子電器的供電電源變換設(shè)備，一般由外殼、電源變壓器和整流電路組成，按其輸出類型可分為交流輸出型和直流輸出型；按連接方式可分為插墻式和桌面式。 </p> <p> 配套于電話子母機(jī)、游戲機(jī)、語言復(fù)讀機(jī)、隨身聽、筆記本計(jì)算機(jī)、蜂窩電話等設(shè)備中。 </p> <p> 多數(shù)筆記本電腦的電源適配器可以適合用于100~240V交流電(50/60Hz)。 </p> <p> 基本上大部份的筆記本電腦都把電源外置，用一條電源線和主機(jī)連接，這樣可以縮小主機(jī)的體積和重量，只有極少數(shù)的機(jī)型把電源內(nèi)置在主機(jī)內(nèi)。 </p> <p> 在電源適配器上都有一個(gè)銘牌，上面標(biāo)示著功率，輸入輸出電壓和電流量等指標(biāo)，特別要注意輸入電壓的范圍，這就是所謂的“旅行電源適配器” </p> <p> <br /> </p> <p> <br /> 新賽電源科技12年來一直堅(jiān)持生產(chǎn)安全電源、品質(zhì)電源，所有電源產(chǎn)品都經(jīng)過安全認(rèn)證，可以放心采購使用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

很多人經(jīng)常把這兩個(gè)概念混淆，轉(zhuǎn)換效率和額定功率其實(shí)沒一毛錢直接關(guān)系。 </p> <p> 轉(zhuǎn)換效率指的是電源本身對(duì)電能的利用率。比如我在使用一個(gè)轉(zhuǎn)換效率為百分之八十的電源。電腦內(nèi)部配件消耗是80W，這時(shí)候用功耗儀去檢測(cè)電源輸入端功耗應(yīng)該是100W。有百分之二十的電量在轉(zhuǎn)換過程中被電源自身損耗掉了。 </p> <p> 而額定功率指的是電源本身能供給電腦硬件多少電。電源銘牌上標(biāo)注的額定功率就是電源的實(shí)際輸出能力。各路功率額定多少瓦就能實(shí)際輸出多少瓦。但是不能超出電源額定總功率。換句話說，電源額定500W，轉(zhuǎn)換效率百分之八十，假如500W全部供給電腦配件。這時(shí)候你檢測(cè)輸入電量應(yīng)該是600W。新賽電源產(chǎn)品除了通過多個(gè)國家和地區(qū)的安規(guī)認(rèn)證，還滿足歐洲** 新的六級(jí)能效的標(biāo)準(zhǔn)，質(zhì)量可靠，節(jié)能又環(huán)保。廣東12v2a電源適配器</p><p style="text-indent:25px">新賽電源適配器采用微電子技術(shù)和先進(jìn)的制造工藝，產(chǎn)品獲得各項(xiàng)安規(guī)認(rèn)證證書、性能穩(wěn)定。廣東12v2a電源適配器</p><p> 電源那些事 </p> <p> 銘牌 </p> <p> 買來電源一眼肯定是要看銘牌的。什么是銘牌？就是電源上哪個(gè)寫著各種參數(shù)的貼紙。 </p> <p> 上面**重要的參數(shù)就是輸入電壓和額定輸出功率。 </p> <p> 一般來說全電壓（能同時(shí)支持國外的110V和國內(nèi)的220V）的肯定是要比220V only的好。 </p> <p> 12V額定輸出決定了你到底能帶什么配置。單路和多路12V稍后會(huì)提到。 </p> <p> 多機(jī)械硬盤的還得注意5V。不過這個(gè)與電源方案也有一定關(guān)系，稍后會(huì)說明。 </p> <p> <span style="font-size:12px;">總的來說，買來一個(gè)電源首先看12V就對(duì)了，只要12V額定輸出大于你CPU+顯卡的zui大功率就說明這個(gè)電源能帶動(dòng)你的電腦。不過這也只能說明能帶動(dòng)，其他一些指標(biāo)也是很重要的。</span> 廣東12v2a電源適配器</p><p
