許多入門級產品運用低(di)成(cheng)本(ben)的粗(cu)(cu)調(diao)/細調(diao)雙(shuang)旋(xuan)(xuan)鈕(niu)(niu)設定(ding)，遇到雙(shuang)調(diao)理旋(xuan)(xuan)鈕(niu)(niu)，咱們先將細調(diao)旋(xuan)(xuan)鈕(niu)(niu)旋(xuan)(xuan)到中心方位，然(ran)后(hou)經過粗(cu)(cu)調(diao)旋(xuan)(xuan)鈕(niu)(niu)設定(ding)大致電(dian)(dian)壓(ya)(ya)，再用細調(diao)旋(xuan)(xuan)鈕(niu)(niu)準確批改。設置(zhi)電(dian)(dian)流(liu)。按下電(dian)(dian)源面板上“Limit”鍵不放，此刻電(dian)(dian)流(liu)表會顯(xian)現電(dian)(dian)流(liu)數值，調(diao)理電(dian)(dian)流(liu)旋(xuan)(xuan)鈕(niu)(niu)，使電(dian)(dian)流(liu)數值到達(da)預訂水平。靠改變變壓(ya)(ya)器次、初級電(dian)(dian)壓(ya)(ya)的相(xiang)位差(cha)，使輸出(chu)交(jiao)流(liu)電(dian)(dian)壓(ya)(ya)穩定(ding)。晶閘(zha)管(guan)交(jiao)流(liu)穩壓(ya)(ya)器。用晶閘(zha)管(guan)作功率調(diao)整元件。穩定(ding)度高、反應快(kuai)且(qie)無噪(zao)聲(sheng)。但(dan)對通信設備和電(dian)(dian)子設備造(zao)成(cheng)干擾。'

穩壓(ya)電(dian)(dian)源的(de)使(shi)用(yong)(yong)(yong)注(zhu)意(yi)事項(xiang)：首先檢(jian)查(cha)電(dian)(dian)源的(de)輸(shu)入、輸(shu)出(chu)端有沒有短(duan)路現(xian)象。然(ran)后(hou)看(kan)看(kan)機箱后(hou)面(mian)板保(bao)險絲座內(nei)保(bao)險絲管是(shi)否裝好(hao)將(jiang)面(mian)板各種(zhong)旋(xuan)鈕，步進選(xuan)擇開關(guan)(guan)調很小(xiao)。檢(jian)查(cha)無(wu)誤后(hou)才可以開機。開機前應根(gen)據需(xu)要將(jiang)輸(shu)出(chu)電(dian)(dian)壓(ya)步進選(xuan)擇開關(guan)(guan)放(fang)在(zai)適當的(de)位置。在(zai)加載過程中不(bu)允許轉換步進選(xuan)擇開關(guan)(guan)的(de)檔位，如需(xu)改變檔位需(xu)將(jiang)負載去掉后(hou)再進行轉換。然(ran)后(hou)，封(feng)閉(bi)電(dian)(dian)源，調低作(zuo)業電(dian)(dian)壓(ya)，三(san)相穩壓(ya)電(dian)(dian)源，就能(neng)正常作(zuo)業了。設定作(zuo)業電(dian)(dian)壓(ya)參閱上文中第三(san)步。不(bu)同的(de)電(dian)(dian)源設置，OVP方(fang)法不(bu)同。通(tong)訊(xun)接口(kou)參數設置和(he)遙控(kong)操(cao)作(zuo)的(de)設置。關(guan)(guan)于本地(di)控(kong)制的(de)運用(yong)(yong)(yong)（面(mian)板操(cao)作(zuo)）要封(feng)閉(bi)遙控(kong)操(cao)作(zuo)。通(tong)訊(xun)接口(kou)要按通(tong)訊(xun)要求(qiu)設定，本地(di)運用(yong)(yong)(yong)則不(bu)需(xu)設置。

注意事項:依據所需求(qiu)的電(dian)壓，先調整(zheng)“粗(cu)(cu)調”旋(xuan)紐(niu)，再(zai)(zai)逐步調整(zheng)“細調”旋(xuan)紐(niu)，要(yao)做到正確合作。例(li)如(ru)需求(qiu)輸出12V電(dian)壓時(shi)，需將(jiang)“粗(cu)(cu)調”旋(xuan)紐(niu)置(zhi)在(zai)15V檔，再(zai)(zai)調整(zheng)“細調”旋(xuan)紐(niu)調置(zhi)12V，而“粗(cu)(cu)調”旋(xuan)紐(niu)不該置(zhi)在(zai)10V檔。
