有時(shí)候筆記本電池突然供電不足需要充電才能繼續(xù)使用，但是沒有帶電源適配器，安徽筆記本電腦電源制造商，安徽筆記本電腦電源制造商，這種情況非常令人焦慮和尷尬。那么電源適配器能通用嗎?選購時(shí)應(yīng)注意什么? </p> <p> <p> 1、注意輸出的電流和電壓范圍。輸出的電流和電壓是選擇適配器的一個(gè)重要指標(biāo)，應(yīng)與需要供應(yīng)電源的電子電器產(chǎn)品要求的電流、電壓相符。若選擇電壓、電流過高，則會(huì)損壞電子電器產(chǎn)品，若選擇電壓、電流過低，則設(shè)備不能正常工作或超負(fù)荷工作而影響安全性能。 </p> <p> 2，安徽筆記本電腦電源制造商、是否有安全認(rèn)證標(biāo)志。電源適配器產(chǎn)品從設(shè)計(jì)到批量生產(chǎn)，需要經(jīng)過一系列的試驗(yàn)，驗(yàn)證其是否符合安全要求。通過我國規(guī)定的安全認(rèn)證試驗(yàn)的產(chǎn)品在銷售時(shí)會(huì)貼上“CCC”標(biāo)志。 </p> <p> 不同電源適配器品牌產(chǎn)品是不能通用的!選購電源適配器時(shí)也需要注意很多!謹(jǐn)慎對(duì)待電器，這樣才能保證我們的安全! </p> <p> <br /> </p> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽筆記本電腦電源制造商" src="http://tyunfile.71360.com/UploadFile/szxskj/637142795552910156/908651.jpg"></div><p> 很多用戶都有這樣的問題，為什么電源適配器之間的價(jià)格差距如此大?電源適配器具有相同的電源、相同的電壓，但價(jià)格差別很大，部件是好的還是壞的?或者它是工作的還是什么的?那么，電源適配器的價(jià)格差是如何產(chǎn)生的? </p> <p> 自從提到價(jià)格以來，整個(gè)電源行業(yè)都有一個(gè)口號(hào)：1瓦1元?？纯?**，很多36W的電源適配器都低于20元的價(jià)格，那么真的應(yīng)該變成1瓦5美分嗎?同行業(yè)的**電源適配器產(chǎn)品，雖然價(jià)格也在下降，但一直處于1瓦1元的水平。 </p> <p> 事實(shí)上，除了上述輸入電壓和功率外，還包括開關(guān)頻率、效率、負(fù)載調(diào)整率、電壓調(diào)整率、電磁干擾/電磁兼容性、散熱、電源動(dòng)態(tài)對(duì)應(yīng)速度、穩(wěn)定性等。然后，電源適配器的具體使用與內(nèi)部使用的電子元件的等級(jí)有關(guān)。 </p> <p> 由于潛在的電氣危害，電源適配器是一種封閉的產(chǎn)品，無法打開。這使得許多用戶只能測量電源適配器銘牌上標(biāo)明的瓦特?cái)?shù)和**直觀的價(jià)格。電源適配器，這個(gè)看似簡單的"塑料盒子"內(nèi)部，遠(yuǎn)沒有我們想象的那么簡單。 </p> <p> 其中，各種功率MOSFET和IGBT的狀態(tài)電阻和開關(guān)電壓升降時(shí)間不同，價(jià)格自然也會(huì)不同。變壓器漏感對(duì)效率也有影響，因此制造/繞組過程的質(zhì)量與效率有關(guān)，也與成本有關(guān)。這就是因?yàn)殡娫催m配器的價(jià)格差是如何產(chǎn)生的原因? </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽筆記本電腦電源制造商" src="http://tyunfile.71360.com/UploadFile/szxskj/637142795370205078/263650.jpg"></div><p> 有時(shí)候筆記本電池突然供電不足需要充電才能繼續(xù)使用，但是沒有帶電源適配器，這種情況非常令人焦慮和尷尬。那么電源適配器能通用嗎?選購時(shí)應(yīng)注意什么? </p> <p> 1、標(biāo)志清晰、信息完整。標(biāo)記是指示使用者正確安裝、使用的重要信息，是確保使用者人身財(cái)產(chǎn)安全的一項(xiàng)**基本的內(nèi)容。至少應(yīng)包含以下信息：制造廠或經(jīng)銷商的名稱、商標(biāo)或識(shí)別標(biāo)記;機(jī)型代號(hào)或型號(hào)規(guī)格;電源性質(zhì);額定電源電壓范圍;輸出電壓范圍等。 </p> <p> 2、留意額定電源電壓范圍。因?yàn)槲覈须婋妷簽?20V，所以在選購適配器時(shí)，其額定電源電壓(即輸入電壓)范圍應(yīng)包含220V，否則適配器不但不能正常使用，而且可能帶來燒毀、擊穿短路等不安全隱患。 </p> <p> 3、注意輸出的電壓性質(zhì)。電源適配器的輸出有交流和直流兩種，在選購時(shí)應(yīng)選取符合預(yù)定使用需要的電壓類型。在電源適配器標(biāo)志上，交流標(biāo)識(shí)的符號(hào)為“～”，直流標(biāo)識(shí)的符號(hào)為“—”。如果選擇輸出為直流的適配器，還應(yīng)考慮輸出端子的正負(fù)極性與設(shè)備要求的一致性。 </p>
