A. AUTOMATICALLY SEQUENCE FUNCTION
每個通道可以單獨設置快速序列,每通道zui多可以建立120個點、延遲時間等,每一步階zui小可設定為100us。在相同的控制模式下,可以同時進行多通道的序列控制,并模擬交換式電源供應器加載行為,這是PEL-2000A系列zui強而有力的特征之一,可運用在多通道輸出電源供應器的模擬。在動態模式下,負載電流或脈沖負載電阻其兩個預置準位的條件設置速度,每一步階可達25us,這通常是作為標準測試程序,以驗證負載快速變化的響應。

右上圖是一張單通道交換式電源供應器仿真負載快速變化的一個范例。透過數字示波器搭配使用電流測棒所截取到的電流波形,PEL- 2000A可程序直流電子負載的序列編程功能,能夠對于交換式電源供應器進行產品的性能測試
 
B. MULTIPLE OPERATING MODE
C.C. ( 定電流運作模式 )
定電流模式下,負載單元根據所設置的值吸入電流量,無論電壓多大,電流保持不變。CC模式下共有兩個檔位:高(HI)與低(LOW)檔位,低檔位的分辨率比高檔位高,用于精密測試,當電流超出低檔位范圍時就需切換配置文件位至高檔位。PEL-2000A系列可程序直流電子負載,低范圍所能承受的功率為該型號zui大的額定功率。CC模式下包含靜態與動態兩個主要模式,靜態模式用于穩定測試,動態模式用于測試瞬間負載,在動態與靜態下也可使用Go /No Go 功能。
 
C.V. ( 定電壓運作模式 )
定電壓模式下負載單元保持電壓不變同時吸取電流,在定電壓模式下,單信道負載其可以設定A & B兩個值以及限制的電流值,亦可透過負載模塊的前面板A/B鍵來切換并選擇A或 B的測試條件。雙信道負載只能設定一個條件值(A值),在CV模式下可以設定響應時間的快慢。
 
C.V.+C.C. ( 恒壓+恒流模式 )
在定電壓模式下,可設定一個電流限制,可進入CV+CC模式。當電壓輸入大于A值,并且輸入電流低于限制電壓時,信道運行在CV模式,當電流大于限制時,信道將進入CC模式。
 
C.R. ( 定電阻模式 )
定電阻模式下負載單元吸收成線性比例的電流與電壓以匹配所設定的電阻值。單通道。單通道有兩種值,2個檔位及上升與下降轉換速率。和CC模式一樣定電阻支持動態與靜態負載,和其他負載一樣,CR模式支持GO/NG功能。
 
C. PARALLEL DYNAMIC LOADING
PEL-2000A主(zhu)控(kong)的(de)每個(ge)通道都可(ke)以并聯(lian)使用,并可(ke)操作在動態(tai)與靜態(tai)模(mo)式下。在動態(tai)模(mo)式下,負載(zai)可(ke)設定兩個(ge)準位,兩準位之間的(de)延遲zui小(xiao)可(ke)設定為0.025ms。當信道并聯(lian)使用時,動態(tai)測試必須要同(tong)步。透過并聯(lian)可(ke)有效的(de)執(zhi)行動態(tai)高功(gong)率負載(zai),無(wu)需采用大(da)功(gong)率的(de)負載(zai)機來提(ti)供(gong)。
 
D. FRAME LINK
PEL-2000A系列可(ke)透過負載控制接(jie)口(kou),連接(jie)多個電(dian)子負載,接(jie)面均為(wei)標準的MIL20-pin接(jie)口(kou),zui多可(ke)以將4個副控機框與(yu)*主機框相互(hu)并接(jie)。
 
E. RUN PROGRAM
在(zai)(zai)編(bian)程序(xu)(xu)列(lie)模式(shi)下,共有12組(zu)編(bian)程序(xu)(xu)列(lie),每(mei)一(yi)組(zu)程序(xu)(xu)中有10個序(xu)(xu)列(lie),透過編(bian)輯參數可(ke)進(jin)行(xing)重復測試(shi)(shi),運行(xing)完(wan)成后,所有的測試(shi)(shi)結果包含GO/NG判斷結果將會(hui)全部顯(xian)示在(zai)(zai)窗(chuang)口上。

G. Von VOLTAGE SETTINGS
Von Voltage指負(fu)載(zai)開始(shi)吸(xi)取電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)時的(de)電(dian)(dian)(dian)(dian)(dian)壓。Von Voltage共(gong)有兩種操作模式:Von Latched 開 及 Von Latched 關 。當Von Latched開,當電(dian)(dian)(dian)(dian)(dian)壓值(zhi)達到Von電(dian)(dian)(dian)(dian)(dian)壓時,負(fu)載(zai)開始(shi)吸(xi)入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu),且電(dian)(dian)(dian)(dian)(dian)壓低于Von電(dian)(dian)(dian)(dian)(dian)壓時,仍然持(chi)續吸(xi)入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。Von Latched 關,電(dian)(dian)(dian)(dian)(dian)壓值(zhi)達到Von電(dian)(dian)(dian)(dian)(dian)壓時,開始(shi)吸(xi)入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu),但當電(dian)(dian)(dian)(dian)(dian)壓值(zhi)低于Von電(dian)(dian)(dian)(dian)(dian)壓時,停止吸(xi)入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。如圖(tu):Von Latched被設置為關閉時,若(ruo)Von-Voltage限制已超過,負(fu)載(zai)模塊將開始(shi)吸(xi)入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu),直至輸出電(dian)(dian)(dian)(dian)(dian)壓下(xia)降于Von-Voltage限制時,才(cai)會停止吸(xi)收電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。
