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銘牌，上面標(biāo)示著功率，輸入輸出電壓和電流量等指標(biāo)，廣東12v2a電源適配器，廣東12v2a電源適配器，廣東12v2a電源適配器，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 /> 深圳市新賽電源是國家高新技術(shù)企業(yè)，生產(chǎn)開關(guān)電源、電源適配器、充電器的廠家。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"

因為在電源適配器的電路中裝有壓敏電阻器，壓敏電阻器在電源適配器中主要用來吸收浪涌電壓。起過電壓保護(hù)、防雷、抑制浪涌電流、吸收尖峰脈沖、限幅、高壓滅弧、消噪、保護(hù)半導(dǎo)體元器件等作用。 </p> <p> <span style="font-size:12px;">壓敏電阻器是一種具有瞬態(tài)電壓抑制功能的元件，可以用來代替瞬態(tài)抑制二極管、齊納二極管和電容器的組合。壓敏電阻器可以對充電器電路中的集成電路IC及其它半導(dǎo)體元件進(jìn)行保護(hù)，防止因靜電放電、浪涌及其它瞬態(tài)電流（如雷擊等）而造成對它們的損壞。</span> </p> <p> 使用時只需將壓敏電阻器并接于被保護(hù)的IC或充電器的交流輸入電路上，當(dāng)電壓瞬間高于某一數(shù)值時，壓敏電阻器阻值迅速下降，導(dǎo)通大電流，從而保護(hù)IC或電器設(shè)備；當(dāng)電壓低于壓敏電阻器工作電壓值時，壓敏電阻器阻值極高，近乎開路，因而不會影響器件或充電器的正常工作。廣東國標(biāo)電源適配器多少錢深圳電源適配器,個性化定制,送貨上門,報價合理,控進(jìn)度,廠家直銷,**出方案,多家客戶認(rèn)可。</p><div

電源適配器中的濾波電容通常使用點解電容，點解電容在工作過程中溫度會很高，它的使用壽命是和溫度成反比的，溫度越高，使用壽命越短。電容的好壞***影響其壽命，一般的公司采用的是壽命幾千個小時的電容，與此相對電源適配器的壽命也就收到限制，我們采用的是行業(yè)排行**的廠家電源，電容壽命一般都是在50000個小時以上，大約在50000個小時候濾波電容會鼓包，電源適配器也就不再工作。 </p> <p> </p><p> 電源適配器體積越小，對轉(zhuǎn)換效率和散熱能力的要求也就越高。將220伏交流電通過變壓、整流、濾波、穩(wěn)壓，輸出適合電器工作電源的一種器件。電源適配器精致做工小巧設(shè)計，***用于加濕器，空氣凈化器，電子冰箱，ED燈具，安防，液晶電視，數(shù)碼產(chǎn)品，監(jiān)控設(shè)備等。新賽電源的工程師通過精心篩選測試，挑選出質(zhì)量好的元器件，優(yōu)化電路結(jié)構(gòu)和制作工藝，實現(xiàn)了更高的效率。 </p> <p> 主要有以下四大特征： </p> <p> 一、強(qiáng)大的研發(fā)團(tuán)隊，以及自主研發(fā)中心和實驗室;專注安規(guī)研發(fā)生產(chǎn)，研發(fā)成果5W-30W電源已投入市場; </p> <p> 二、采用微電子技術(shù)和先進(jìn)的制造工藝，高精度，低噪音;過壓、過流、過充，短路等多重保護(hù); </p> <p> 三、獲得C B、C E、U L、K C、G S、F C C、C C C、S A A、P S E等安規(guī)認(rèn)證證書、性能穩(wěn)定; </p> <p>

我們經(jīng)常會收到一個關(guān)于如何找替代電源適配器的問題，其中大多是關(guān)于AC-DC電源適配器的，那么這里面有沒有什么竅門呢？ </p> <p> 我們首先會問客戶是否有一個零件編號或者型號, 又或者問他們有沒有電壓和電流上的需求。大多數(shù)電源適配器的標(biāo)簽上是可以找到以下信息的： </p> <p> 零件編號/ 型號、輸入、輸出 </p> <p> 需要注意的一點是, 在這個標(biāo)簽上有一個正極中心標(biāo)識符, 它表示的是中心線接正極。雖然這是個常見的配置, 但是這一點比較重要。如果你用一個正極中心的適配器替代一個負(fù)極中心的適配器,可能會損壞電路。 </p> <p> 可是有些時候, 從這個適配器上的安裝類型, 我們未必能夠找到一樣類型的適配器。此時, 我們需要看看一些別的信息。首先, 根據(jù)上面的信息, 知道我們需要12VDC的輸出, 因此選擇了12V。 </p> <p> 下一步你需要選擇電源的輸出電流。模板中輸出電流為1A,但是為了有更多的選擇, </p> <p> 所以在這里建議選擇所有輸出電流大于等于1A的。 </p> <p> 下一步你需要選擇電源的輸出電流。模板中輸出電流為1A,但是為了有更多的選擇, </p> <p> 所以在這里建議選擇所有輸出電流大于等于1A的。 </p> <p>

動態(tài)性能指的是電源在負(fù)載大起大落時候的瞬間的電壓變動。這個包括電壓的變化和電壓的波形。在負(fù)載高低變化的一瞬間，電壓越穩(wěn)定越好，波形越接近一條直線越好。因為這個測試目前還沒有一個固定的標(biāo)準(zhǔn)。而且一般也遇不到這種情況，所以一般只是作為一個對比參考。 </p> <p> 5.保持時間 </p> <p> 保持時間指的是突然斷電后，各路電壓正常輸出的時間，這個時間主要是由主電容容量決定的。其主要目的是為了給一些硬件作出應(yīng)急處理的時間，比如機(jī)械硬盤磁頭歸位，固態(tài)的掉電保護(hù)等等。一般來說主電容容量比較好大于每瓦0.5微法。廣東12v2a電源適配器</p><p
