恒壓恒流電源多(duo)種(zhong)多(duo)樣，那么我們又了解多(duo)少呢，今天(tian)我們就來看一下，具體認(ren)識幾種(zhong)恒(heng)壓恒(heng)流電源及其特(te)點。

　　類(lei)型1恒(heng)(heng)壓(ya)(ya)(ya)恒(heng)(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)中的(de)(de)(de)普(pu)(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan):都(dou)是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)源(yuan)(yuan)(yuan)，額定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)就是(shi)(shi)(shi)最大(da)(da)的(de)(de)(de)輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。所謂恒(heng)(heng)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，就是(shi)(shi)(shi)說(shuo)無論輸(shu)(shu)出(chu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)是(shi)(shi)(shi)怎樣的(de)(de)(de)，它的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)不變(bian)。當(dang)然(ran)(ran)，任何恒(heng)(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)都(dou)是(shi)(shi)(shi)相對的(de)(de)(de)，由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)都(dou)有(you)內阻這(zhe)是(shi)(shi)(shi)不可(ke)避免的(de)(de)(de)，因此會下(xia)降一(yi)點點，但幾乎可(ke)以(yi)忽略(lve)。有(you)些普(pu)(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)可(ke)以(yi)調(diao)節，即便不可(ke)調(diao)也可(ke)通(tong)過(guo)(guo)改變(bian)內部的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻實現微(wei)調(diao)。當(dang)然(ran)(ran)，這(zhe)樣的(de)(de)(de)調(diao)節不建議(yi)范(fan)(fan)圍過(guo)(guo)大(da)(da)，恒(heng)(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)調(diao)節低(di)了會降低(di)效(xiao)率(lv)，所以(yi)得(de)(de)把(ba)持一(yi)個適當(dang)的(de)(de)(de)度。普(pu)(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)隨(sui)著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)元件的(de)(de)(de)增多(duo)和(he)加重，輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)超額，過(guo)(guo)熱甚至(zhi)燒(shao)壞，這(zhe)就是(shi)(shi)(shi)它們(men)的(de)(de)(de)弊端(duan)。恒(heng)(heng)壓(ya)(ya)(ya)恒(heng)(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)中的(de)(de)(de)普(pu)(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)短(duan)路(lu)(lu)后(hou)，瞬間(jian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)非常(chang)大(da)(da)，所以(yi)工作人(ren)員(yuan)需要(yao)謹慎操(cao)作，還會可(ke)能燒(shao)壞外部電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)本(ben)身。為了防止(zhi)恒(heng)(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)過(guo)(guo)流(liu)(liu)(liu)或(huo)短(duan)路(lu)(lu)，采取限流(liu)(liu)(liu)可(ke)以(yi)把(ba)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)限制在安全范(fan)(fan)圍內，這(zhe)樣就相對安全啦。但有(you)些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)短(duan)路(lu)(lu)保護無效(xiao)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)仍然(ran)(ran)很大(da)(da)，那么這(zhe)樣的(de)(de)(de)話就得(de)(de)另尋舉措(cuo)另當(dang)別(bie)論了。

　　類型2恒(heng)壓恒(heng)流電(dian)源(yuan)(yuan)中的保(bao)護(hu)電(dian)源(yuan)(yuan)也是一種恒(heng)壓電(dian)源(yuan)(yuan)，正常輸出(chu)時(shi)(shi)與普通電(dian)源(yuan)(yuan)一樣，一旦短(duan)路(lu)，其內部將(jiang)產生保(bao)護(hu)動作(zuo)切斷輸出(chu)。保(bao)護(hu)動作(zuo)后，需(xu)要手動恢復(fu)。如果此時(shi)(shi)外部負(fu)載正常，才能恢復(fu)成功。有些電(dian)源(yuan)(yuan)自(zi)己可以定時(shi)(shi)自(zi)動恢復(fu)那么這樣就更好(hao)了。如果外電(dian)路(lu)正常則(ze)恢復(fu)供電(dian)，若(ruo)不正常則(ze)將(jiang)重新(xin)回到保(bao)護(hu)狀態。

　　類(lei)型3恒(heng)壓恒(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)中的(de)(de)(de)維(wei)(wei)修(xiu)(xiu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)也就(jiu)是(shi)(shi)恒(heng)壓恒(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)，而(er)且電(dian)(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)都是(shi)(shi)可調(diao)(diao)節的(de)(de)(de)范圍很大，從零開(kai)始調(diao)(diao)起(qi)。所(suo)謂恒(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)，就(jiu)是(shi)(shi)把輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)維(wei)(wei)持在(zai)設定(ding)值。負載越重電(dian)(dian)(dian)(dian)(dian)壓就(jiu)越低(di)，所(suo)以一(yi)定(ding)要控制適當的(de)(de)(de)負載量。維(wei)(wei)修(xiu)(xiu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)(de)外(wai)表(biao)美觀，特點鮮明(ming)，所(suo)以一(yi)般的(de)(de)(de)操作在(zai)旋鈕上(shang)進行則(ze)可。有些粗細調(diao)(diao)雙(shuang)鈕都有的(de)(de)(de)，也有些是(shi)(shi)多圈(quan)可調(diao)(diao)的(de)(de)(de)，更高端的(de)(de)(de)話當然就(jiu)是(shi)(shi)數(shu)字輸入的(de)(de)(de)，所(suo)以它的(de)(de)(de)特點真是(shi)(shi)極(ji)明(ming)顯的(de)(de)(de)。當負載比較輕的(de)(de)(de)時候(hou)，電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)恒(heng)壓輸出(chu)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)逐漸加大，到達(da)設定(ding)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)值之后(hou)如(ru)果負載繼續增加，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)就(jiu)保持恒(heng)定(ding)，這就(jiu)是(shi)(shi)恒(heng)流(liu)(liu)(liu)區域。恒(heng)壓恒(heng)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)中的(de)(de)(de)維(wei)(wei)修(xiu)(xiu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)直到輸出(chu)短(duan)路，輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)也保持在(zai)限(xian)流(liu)(liu)(liu)值所(suo)以十分安(an)全(quan)。

　　恒(heng)壓恒(heng)流(liu)電源(yuan)大致就(jiu)(jiu)介紹這幾種類(lei)型(xing)，它們(men)的統一(yi)點(dian)就(jiu)(jiu)是安全，能限定一(yi)定的電流(liu)范圍，當然不同點(dian)更多，那(nei)么其他類(lei)型(xing)的恒(heng)壓恒(heng)流(liu)電源(yuan)等待你(ni)的挖掘和發現。
