天(tian)津直流電子負(fu)載采用(yong)數字控制技術，通(tong)過微處理器實現對(dui)電源的調(diao)整和測試。該設備具有精度高、穩定(ding)性(xing)(xing)好等特點(dian)；可實現大(da)電流輸出并具備多種(zhong)保(bao)護功(gong)能(neng)(neng)（如：浪涌過壓/欠壓保(bao)護）；操作簡(jian)便(bian)易(yi)用(yong)且等優勢廣泛應用(yong)于科研單位及生產廠家(jia)對(dui)開關型穩態特性(xing)(xing)及其它(ta)電路性(xing)(xing)能(neng)(neng)參數進行恒流源測量與老化篩選以及種(zhong)精密儀(yi)器設備的校驗工具等優點(dian)。。

機(ji)箱采用干(gan)式(shi)負載交流單元，測(ce)量發電機(ji)和UPS的(de)主要(yao)功(gong)(gong)能，如穩(wen)定的(de)三相電壓、電流、有功(gong)(gong)功(gong)(gong)率(lv)、無功(gong)(gong)功(gong)(gong)率(lv)、視在功(gong)(gong)率(lv)、功(gong)(gong)率(lv)比、頻(pin)率(lv)、運(yun)行時(shi)間、儲(chu)能等。

干(gan)式負(fu)載(zai)箱(xiang)(柜)主要用(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)源、電(dian)(dian)(dian)(dian)信(xin)和(he)(he)大功(gong)(gong)率(lv)(lv)(lv)UPS廠(chang)家的線(xian)路(lu)、變(bian)頻(pin)器、斷路(lu)器、柴油發電(dian)(dian)(dian)(dian)機等行業的電(dian)(dian)(dian)(dian)源測(ce)試、老(lao)化等。單(dan)一輸入(ru)電(dian)(dian)(dian)(dian)源切(qie)斷，KPEL-M系(xi)列低(di)電(dian)(dian)(dian)(dian)壓高(gao)電(dian)(dian)(dian)(dian)流(liu)直流(liu)電(dian)(dian)(dian)(dian)子負(fu)載(zai)，耗電(dian)(dian)(dian)(dian)模(mo)式和(he)(he)強制(zhi)風冷散熱大大保證了恒功(gong)(gong)率(lv)(lv)(lv)放電(dian)(dian)(dian)(dian)的可靠性;內部燃料元件(jian)采用(yong)(yong)干(gan)式電(dian)(dian)(dian)(dian)阻和(he)(he)強制(zhi)風冷。三相交互式RLC負(fu)載(zai)，又稱交流(liu)RLC負(fu)載(zai)，主要用(yong)(yong)于(yu)(yu)變(bian)頻(pin)器檢(jian)測(ce)、變(bian)頻(pin)器功(gong)(gong)率(lv)(lv)(lv)檢(jian)測(ce)、發電(dian)(dian)(dian)(dian)機檢(jian)測(ce)等領域。老(lao)化測(ce)試與鑒定(ding)試驗中使用(yong)(yong)的精度和(he)(he)功(gong)(gong)能要求(qiu)不同。

在CR或CV模式下(xia)，負載可以驅動超(chao)過額定電(dian)流(liu)的電(dian)流(liu)，從(cong)而觸發過電(dian)流(liu)保護。過電(dian)壓點略(lve)高于此階段電(dian)流(liu)塊的值。在觸發過電(dian)流(liu)保護后，狀態寄存器中的過電(dian)壓(OC)和(he)電(dian)流(liu)誤差(CE)數據位(wei)是有用的，并一直保留(liu)到復位(wei)。

超過輸(shu)(shu)出(chu)功率的(de)點設(she)置為略高(gao)于當前階段的(de)輸(shu)(shu)出(chu)功率的(de)文檔。發生輸(shu)(shu)出(chu)電(dian)源(yuan)(yuan)中斷(duan)后，狀態(tai)寄存器(qi)中的(de)輸(shu)(shu)出(chu)電(dian)源(yuan)(yuan)中斷(duan)(OP)和(he)輸(shu)(shu)出(chu)電(dian)源(yuan)(yuan)錯誤(PE)數據(ju)位(wei)是有用的(de)，并一直保(bao)留(liu)到復位(wei)。LOAD(加載)按鈕(niu)可重置狀態(tai)選項卡。
