固緯PEL-3031E直流電子負(fù)載
PEL-3000E系列是一款可程式單通道電子負(fù)載，PEL-3031E提供300W(1V~150V/60A)電流吸汲能力。承襲PEL-3000系列之LCD面板及操作界面，操作簡單，視覺上一目瞭然。此款為固緯針對(duì)中低功率電子元器件、電池、行動(dòng)電源、電源類產(chǎn)品需求所提供的高速且精準(zhǔn)量測(cè)測(cè)試機(jī)種。
PEL-3000E系列適用於60mA以上電流吸汲及量測(cè)應(yīng)用，包含charger/ Adaptor和各種電源供應(yīng)單元及可攜式充電裝置之量測(cè)應(yīng)用。
PEL-3000E 提供了七種操作模式，分別為定電流、定電壓、定電阻、定功率等四種基本操作模式再加上定電流加定電壓、定電阻加定電壓、定功率加定電壓模式，使用者可依照產(chǎn)品的需求測(cè)試，選擇不同的操作模式。在定電流模式，電子負(fù)載會(huì)依據(jù)設(shè)定的電流值，吸汲一個(gè)固定電流值。在定電壓模式，電子負(fù)載控制吸汲電流，維持電子負(fù)載的輸入端電壓為一個(gè)定值。在定電阻模式，電子負(fù)載會(huì)依據(jù)所設(shè)定的電阻值吸汲電流，吸汲(線性)正比於輸入電壓的電流值。在定功率模式，電子負(fù)載依據(jù)所設(shè)定的功率，將消耗負(fù)載功率(負(fù)載電壓x負(fù)載電流)。
依據(jù)測(cè)試條件的不同，用戶可以使用靜態(tài)(Static)功能產(chǎn)生一個(gè)固定負(fù)載吸汲條件、動(dòng)態(tài)功能(Dynamic)週期性地執(zhí)行兩個(gè)吸汲條件之間切換或Sequence功能提供二個(gè)吸汲條件以上的測(cè)試。Sequence功能可分為Normal Sequence和 Fast Sequence。Normal Sequence功能是*彈性的方式去產(chǎn)生複雜吸汲條件。可供使用者依序設(shè)定不同吸汲條件(CC, CR, CV or CP模式)及時(shí)間(可設(shè)定範(fàn)圍: 1ms to 999h 59min 59s)來建立一組有變化的吸汲條件。而Fast Sequence可設(shè)定*小的步階(step)時(shí)間解晰度為25us，利用多組步階(step)參數(shù)的設(shè)定，可以讓使用者模擬各種實(shí)際負(fù)載的連續(xù)電流變化。例如: 電動(dòng)工具模擬測(cè)試。使用示波器及電流探棒的量測(cè)，紀(jì)錄電動(dòng)工具操作時(shí)的電流波形，經(jīng)由電子負(fù)載sequence參數(shù)設(shè)定模擬電流波形，測(cè)試電源裝置並分析電動(dòng)工具運(yùn)作狀態(tài)。Soft start功能可供使用者決定吸汲電流的上升時(shí)間，以多少時(shí)間到達(dá)電子負(fù)載所設(shè)定的電流或電阻或功率值。適當(dāng)?shù)脑O(shè)定Soft Start的上升時(shí)間，對(duì)於待測(cè)物(電源)瞬間的輸出電流所造成的輸出電壓擾動(dòng)，可以有效的抑制。一般的DC load沒有Soft start功能，當(dāng)進(jìn)行高速吸汲電流的控制時(shí)，因?yàn)殡娮迂?fù)載與待測(cè)物之間連結(jié)線的電感效應(yīng)，所以在電子負(fù)載輸入端產(chǎn)生瞬間壓降，因此造成輸出電壓反單調(diào)遞增(Non-monotonic increase). 而透過PEL-3000E的soft start功能不僅輸出電壓可以符合單調(diào)遞增(Monotonic increase)，而且可避免Inrush current及surge voltage在待測(cè)物端的產(chǎn)生。例如: 利用power supply+ LED+ DC load(啟動(dòng)Soft start)可避免Inrush current及surge voltage對(duì)LED造成損害。
PEL-3000E具有計(jì)時(shí)(count Time)功能可以得知電子負(fù)載吸汲電流的時(shí)間，幫助使用者估算出待測(cè)物功率容量。計(jì)時(shí)關(guān)閉(cut off Time)功能，使用者可以利用此項(xiàng)功能控制電子負(fù)載吸汲電流時(shí)間，彈性的控制時(shí)間，可以增加電子負(fù)載測(cè)試的靈活性。UVP過低輸入電壓保護(hù)功能可應(yīng)用於電池放電測(cè)試，當(dāng)電池的工作電壓低於UVP的設(shè)定值時(shí)，電子負(fù)載停止對(duì)電池吸汲電流避免過度放電，藉以保護(hù)電池。除此之外PEL-3000E系列提供類比控制(Analog Control)端子。供使用者以外部電壓, 外部電阻和開關(guān)控制PEL-3000E，也可從類比控制(Analog Control)端子監(jiān)視電子負(fù)載狀態(tài)及顯示保護(hù)警報(bào)等。
