產品(pin)概述(shu)

負載仿真應用

63200系列(lie)有定電流、定電阻(zu)、定功(gong)率與定電壓四種操作模式。

定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)與定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻模式(shi)對于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓源的(de)(de)(de)(de)待測物(wu)(wu)測試(shi)，可確認待測物(wu)(wu)在(zai)不同的(de)(de)(de)(de)負載(zai)(zai)情況下，輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓是否(fou)(fou)仍維持穩定(ding)輸出。對于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器或(huo)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)樁(zhuang)而言(yan)，定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓模式(shi)可以改變充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器或(huo)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)樁(zhuang)的(de)(de)(de)(de)輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，以確保(bao)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器或(huo)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)樁(zhuang)在(zai)所設(she)定(ding)的(de)(de)(de)(de)輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓時充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)是否(fou)(fou)正(zheng)確。另外(wai)，當待測物(wu)(wu)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負載(zai)(zai)則可轉變為仿真電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設(she)備拉(la)載(zai)(zai)的(de)(de)(de)(de)行為，許多(duo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)應用、功率消(xiao)耗(hao)等情況都(dou)可藉由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負載(zai)(zai)的(de)(de)(de)(de)仿真拉(la)載(zai)(zai)行為來進(jin)行電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)分析，而定(ding)功率模式(shi)則是仿真電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設(she)備拉(la)載(zai)(zai)行為的(de)(de)(de)(de)選擇(ze)。

低電壓操(cao)作特性(xing)

低壓(ya)(ya)/大電流的(de)應用，具有低電壓(ya)(ya)操作(zuo)特性的(de)63200系(xi)列(lie)采用閉回路的(de)設(she)計方(fang)式將所(suo)有功率晶(jing)體(ti)(ti)(ti)并聯(lian)(lian)控(kong)制，以確保高精度、低漂(piao)移量的(de)負(fu)載控(kong)制。 因功率晶(jing)體(ti)(ti)(ti)并聯(lian)(lian)的(de)控(kong)制方(fang)式，使(shi)得輸(shu)入阻抗(kang)至最小化并使(shi)得63200系(xi)列(lie)能在低壓(ya)(ya)時進行大電流的(de)拉(la)載。例(li)如，型號63209即可于輸(shu)入電壓(ya)(ya)1V時拉(la)載 1,000A。

量測

63200系列(lie)內(nei)建15位的(de)高精密A/D轉換器(qi)，可(ke)達電(dian)壓 0.05%+0.05%F.S.、電(dian)流(liu) 0.1%+0.1%F.S.與功(gong)率0.3%+0.3%F.S.的(de)量測(ce)精準度。電(dian)壓、電(dian)流(liu)、功(gong)率 的(de)量測(ce)值可(ke)同時在電(dian)子負載(zai)前面板的(de)LED顯示(shi)器(qi)上顯示(shi)量測(ce)值，除此之外，63200系列(lie)還額外提供電(dian)壓、電(dian)流(liu)的(de)監控輸出(chu)，使(shi)用者可(ke)藉由(you)此二端子 透過示(shi)波(bo)器(qi)監控電(dian)壓、電(dian)流(liu)的(de)輸出(chu)波(bo)形。

動(dong)態負載與控制

在(zai)快速(su)的時(shi)代里，電(dian)子(zi)組件皆朝高(gao)速(su)運作(zuo)的方(fang)向設計(ji)，因此，電(dian)源(yuan)組件對于瞬(shun)時(shi)的信(xin)號及動(dong)態響應(ying)的性能(neng)要(yao)求，比過去(qu)都高(gao)出許多。為(wei)(wei)滿足這些 測試應(ying)用與(yu)要(yao)求，63200系列(lie)提供(gong)高(gao)速(su)、可(ke)(ke)編(bian)程(cheng)動(dong)態負(fu)載仿真(zhen)與(yu)同步動(dong)態負(fu)載等功能(neng)。下(xia)(xia)圖(tu)所示為(wei)(wei)可(ke)(ke)編(bian)程(cheng)的參數：設定電(dian)流(liu)高(gao)/低準位、T1/T2、爬(pa)(pa) 升率(lv)(lv)/下(xia)(xia)降(jiang)率(lv)(lv)。可(ke)(ke)編(bian)程(cheng)的電(dian)流(liu)爬(pa)(pa)升率(lv)(lv)/下(xia)(xia)降(jiang)率(lv)(lv)可(ke)(ke)用來仿真(zhen)真(zhen)實負(fu)載情(qing)況的瞬(shun)時(shi)負(fu)載變(bian)化仿真(zhen)。63200系列(lie)中，在(zai)負(fu)載電(dian)流(liu)連續變(bian)化時(shi)，內部的監測機(ji) 制(zhi)與(yu)線路能(neng)使得電(dian)流(liu)波形失真(zhen)度達(da)到最(zui)小化，電(dian)流(liu)爬(pa)(pa)升率(lv)(lv)最(zui)快可(ke)(ke)達(da)25A/μs (63208)、動(dong)態變(bian)化可(ke)(ke)高(gao)達(da)20kHz。

主/從式并聯控制

當負載功(gong)率需求增(zeng)加時(shi)(shi)，63200系列具(ju)有(you)(you)智(zhi)能型(xing)主(zhu)(zhu)/從控制模式(shi)(shi)，可透(tou)過主(zhu)(zhu)/從控制的(de)(de)(de)并(bing)聯(lian)方式(shi)(shi)達(da)到(dao)所需的(de)(de)(de)電流(liu)及功(gong) 率。當設定成(cheng)(cheng)(cheng)主(zhu)(zhu)/從控制模式(shi)(shi)時(shi)(shi)，用(yong)戶僅需在主(zhu)(zhu)機(ji)上(shang)編程(cheng)負載電流(liu)，主(zhu)(zhu)機(ji)經過自動計算(suan)后會(hui)將(jiang)電流(liu)分配至其他從機(ji)，如此可大大簡化使(shi)用(yong)者的(de)(de)(de)操作(zuo)步驟。簡言(yan)之，用(yong)戶在并(bing)聯(lian)63200系列時(shi)(shi)，僅需將(jiang)所有(you)(you)設定成(cheng)(cheng)(cheng)主(zhu)(zhu)/從控制的(de)(de)(de) 電子(zi)負載，當成(cheng)(cheng)(cheng)一負載即可。同(tong)電壓規格但(dan)不同(tong)型(xing)號的(de)(de)(de)63200系列皆可并(bing)聯(lian)在一起，最多可高達(da)六(liu)臺同(tong)時(shi)(shi)并(bing)聯(lian)。

任意波形(xing)模擬

63200系列電(dian)子負(fu)載可透過計算(suan)機將預(yu)先儲存的(de)電(dian)流波(bo)形(xing)透過DAQ卡或(huo)任意(yi)波(bo)形(xing)產生器將波(bo)形(xing)傳(chuan)送至(zhi)電(dian)子負(fu)載進行拉載。任意(yi)波(bo)形(xing)仿真的(de)功能可觀察
待測物(wu)應用在該領域(yu)時所遇到的(de)真實波形(xing)是否能維持正常(chang)運作。

短(duan)路模(mo)擬

致茂的(de)(de)(de)63200系(xi)列電子(zi)負(fu)載也可仿(fang)真(zhen)待測物短路(lu)時(shi)的(de)(de)(de)情況。直流(liu)(liu)電源或直流(liu)(liu)電源供應器的(de)(de)(de)短路(lu)測試(shi)是必要的(de)(de)(de)測試(shi)項目(mu)之(zhi)一，63200系(xi)列電子(zi)負(fu)載以 最(zui)大額(e)定(ding)電流(liu)(liu)的(de)(de)(de)拉(la)載方式進行短路(lu)模擬(ni)，因此(ci)可用(yong)來模擬(ni)待測物的(de)(de)(de)短路(lu)保護功能是否有正常動作。

瞬(shun)間2.7倍額定(ding)功率(lv)能力

63200系(xi)列(lie)電(dian)(dian)子負(fu)載提供*的(de)浪涌負(fu)載仿真(zhen)能力(li)，可使 63200系(xi)列(lie)電(dian)(dian)子負(fu)載功(gong)率瞬間過載2.7倍的(de)額定(ding)功(gong)率。此特性 非常適合應(ying)用在待(dai)測(ce)物進(jin)行瞬間峰值功(gong)率的(de)供給(gei)能力(li)，電(dian)(dian)漿 電(dian)(dian)視(shi)(PDP)電(dian)(dian)源就是(shi)一種典型的(de)應(ying)用，其他應(ying)用則例如電(dian)(dian)池的(de) 3C放(fang)電(dian)(dian)、斷路器與無熔絲(si)開關的(de)過載(300%至1,000%)測(ce)試、 汽車(che)引擎啟(qi)動時(shi)的(de)負(fu)載仿真(zhen)及直流馬達的(de)啟(qi)動模擬等(deng)。

依(yi)據63200系列電子負(fu)(fu)載(zai)的(de)(de)初始(shi)負(fu)(fu)載(zai)情況，會(hui)有不同的(de)(de)浪涌(yong) 負(fu)(fu)載(zai)能(neng)力，如圖1與(yu)(yu)圖2的(de)(de)關(guan)系圖所示，圖中顯示的(de)(de)是初始(shi)負(fu)(fu) 載(zai)與(yu)(yu)可過載(zai)的(de)(de)最大負(fu)(fu)載(zai)能(neng)力與(yu)(yu)時間關(guan)系。當使用(yong)浪涌(yong)負(fu)(fu)載(zai)功 能(neng)時，如果(guo)超出圖1及(ji)圖2中所顯示的(de)(de)最大浪涌(yong)負(fu)(fu)載(zai)能(neng)力時， 電子負(fu)(fu)載(zai)會(hui)顯示過功率保護(OPP)，并停(ting)止拉(la)載(zai)。

63200系列包含*的時(shi)間與量(liang)測(ce)功能設(she)(she)計(ji)，量(liang)測(ce)范圍(wei)為2 秒~99,999秒，此(ci)精(jing)準的時(shi)間量(liang)測(ce)特性可(ke)應(ying)用(yong)在電(dian)池放電(dian)測(ce) 試與其他相同應(ying)用(yong)上，使用(yong)者(zhe)需在進行電(dian)池放電(dian)測(ce)試時(shi)設(she)(she) 定(ding)終止(zhi)拉載(zai)電(dian)壓(ya)及(ji)停(ting)止(zhi)拉載(zai)時(shi)間。例(li)如 : 當按下(xia)Load ON開(kai) 始拉載(zai)，63200系列的內(nei)部定(ding)時(shi)器會自動(dong)開(kai)始計(ji)數(shu)，直到 電(dian)池電(dian)壓(ya)降至所(suo)設(she)(she)定(ding)的終止(zhi)電(dian)壓(ya)或(huo)當按下(xia)Load OFF停(ting)止(zhi)拉 載(zai)，定(ding)時(shi)器才會停(ting)止(zhi)計(ji)數(shu)。時(shi)間量(liang)測(ce)功能可(ke)應(ying)用(yong)在電(dian)池與 超電(dian)容的放電(dian)時(shi)間、保險絲及(ji)斷路(lu)器的跳脫時(shi)間和(he)其他相 同應(ying)用(yong)等。
