**功能指所有的輸出同時(shí)被控制，并且通過保持電壓與事先設(shè)定的電壓一致，河南直流電源規(guī)范，使它們都服從統(tǒng)一指揮。 </p> <p> 例如：如果電壓1從10V變?yōu)?2V，河南直流電源規(guī)范，則電壓2和3將隨之從5V變?yōu)?V，電壓4隨之從20V變?yōu)?4V。 </p> <p> 但是，如果其中一個(gè)處于領(lǐng)導(dǎo)位置的輸出的比較大電流存在極限值，而且輸出電流達(dá)到該極限值時(shí)，則所有其他處于從屬地位的輸出電流也同時(shí)進(jìn)入限流狀態(tài)，河南直流電源規(guī)范。 </p> <p> 如果設(shè)備中安裝了電子保險(xiǎn)絲，則到達(dá)該極限值的輸出將被斷開，進(jìn)而其他處于從屬位置的輸出也全部被斷開。 </p> <p> <br /> 高頻開關(guān)直流電源多少錢。河南直流電源規(guī)范</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

任何對(duì)元器件、電路板、模塊或設(shè)備進(jìn)行測(cè)試時(shí)都需要使用一個(gè)或多個(gè)直流電源來給被測(cè)物和測(cè)試激勵(lì)源供電。 </p> <p> 除了給被測(cè)物供電外，這些電源有時(shí)也可通過模擬被測(cè)物工作環(huán)境來提供測(cè)試激勵(lì)。比如，多范圍的充電機(jī)，可以充電12VDC或者24VDC電池組，比較高充電電壓會(huì)達(dá)到28.8VDC左右；針對(duì)電子產(chǎn)品，常規(guī)測(cè)試項(xiàng)目都會(huì)包含對(duì)產(chǎn)品進(jìn)行OVP測(cè)試，OVP測(cè)試所采用的電壓通常都會(huì)比額定工作電壓高10%甚至20%；針對(duì)采用額定12VDC電壓的汽車電路，但比較大輸入電壓仍可能高達(dá)27VDC，因此，某些汽車標(biāo)準(zhǔn)要求用27VDC的電壓對(duì)正常工作電壓為12VDC的裝置進(jìn)行極限測(cè)試。這類基本因素決定了人們對(duì)電源的要求。 </p> <p> 在購買直流電源前，根據(jù)您的應(yīng)用類型決定選用線性電源還是開關(guān)電源。線性電源紋波和噪聲低、瞬態(tài)響應(yīng)快，但效率低、發(fā)熱量大，而且又大又重，一般情況下，在要求紋波和噪聲低、瞬態(tài)響應(yīng)快的情況下才可能選擇。 </p> <p> <br /> 進(jìn)口便攜式交直流電源。</p><div

可編程直流電源，在航天航空領(lǐng)域主要用于DC-DC電源模塊、蓄電池、飛行模擬器等直流用電設(shè)備的測(cè)試?？煽啃詼y(cè)試用電設(shè)備的可靠性測(cè)試通常包括電壓跌落測(cè)試、溫升測(cè)試、ON/OFF測(cè)試、老化測(cè)試等。而對(duì)于航天航空用電設(shè)備來說，要進(jìn)行比常規(guī)更為嚴(yán)苛的測(cè)試，要求用電設(shè)備不僅能在正常供電情況下穩(wěn)定工作，還要能應(yīng)付供電異常的狀況。 </p> <p> <br /> </p> <p> 例如：在飛機(jī)上，供電系統(tǒng)給各種各樣的直流用電設(shè)備供電，而飛機(jī)上的供電系統(tǒng)有時(shí)會(huì)存在過壓或欠壓的狀況，保證用電設(shè)備在這些異常情況下正常工作，就是對(duì)飛機(jī)功能性以及安全性的保證。因此，過欠壓測(cè)試必不可少。直流電源在該測(cè)試中用以模擬供電系統(tǒng)，通過輸出一個(gè)連續(xù)的電壓變化波形來模擬飛機(jī)供電系統(tǒng)的電壓變化，對(duì)用電設(shè)備進(jìn)行供電，測(cè)試用電設(shè)備是否會(huì)在過壓、欠壓、正常電壓這三種不同的電壓狀態(tài)下都能保持正常工作。圖1是在對(duì)飛機(jī)上的用電設(shè)備做過欠壓測(cè)試時(shí)利用直流電源模擬飛機(jī)供電系統(tǒng)輸出的電壓波形：寬范圍可編程直流電源。河南是德直流電源可編程</p><p

（二）整流器：整流器采用三相全控橋式整流電路，它包括六個(gè)快速熔斷器、六個(gè)晶閘管、六個(gè)脈沖變壓器和一個(gè)續(xù)流二極管。在快速熔斷器上有一個(gè)紅色的指示器，正常時(shí)指示器縮在外殼里邊，當(dāng)快熔燒斷后它將彈出，有些快熔的指示器較緊，當(dāng)快熔燒斷后，它會(huì)卡在里面，所以為可靠起見，可以用萬用表通斷檔測(cè)一下快熔，以判斷它是否燒斷。 </p> <p> 測(cè)量晶閘管的簡(jiǎn)單方法是用萬用表電阻擋（200Ω擋）測(cè)一下其陰極—陽極、門極—陰極電阻，測(cè)量時(shí)晶閘管不用取下來。正常情況下，陽極—陰極間電阻應(yīng)為無窮大，門極—陰極電阻應(yīng)在10—50Ω之間，過大或過小都表明這只晶閘管門極失效，它將不能被觸發(fā)導(dǎo)通。 </p> <p> 脈沖變壓器次邊接在晶閘管上，原邊接在主控板上，用萬用表測(cè)量原邊電阻約為50Ω。續(xù)流二極管一般不容易出現(xiàn)故障，檢查時(shí)用萬用表二極管擋測(cè)其二端，正向時(shí)萬用表顯示結(jié)壓降約有500mV，反向不通。 </p> <p> （三）逆變器：逆變器包括四只快速晶閘管和四只脈沖變壓器，可以按上述方法檢查。 </p> <p> <br />
