您好, 歡迎來到化工儀器網(wǎng)
產(chǎn)品簡介
詳細(xì)介紹
PEL-2000可編程直流電子負(fù)載，此電子負(fù)載可以工作在定電流、定電壓、定電阻模式下，還可模擬各種動(dòng)態(tài)負(fù)載狀況，透過序列功能進(jìn)行負(fù)載電壓、電流、負(fù)載的上升及下降斜率、電流準(zhǔn)位、持續(xù)時(shí)間等參數(shù)來編輯負(fù)載波形，同時(shí)提供外部波形信號(hào)控制以及V&I監(jiān)測功能，測試參數(shù)及狀態(tài)的存儲(chǔ)可高達(dá)120組，系統(tǒng)可根據(jù)自動(dòng)測試需求，隨時(shí)由儀器內(nèi)部的儲(chǔ)存單元EEPROM中呼叫出來使用。
PEL-2000系列包含兩種主控含機(jī)框PEL-2002(可容納雙模組)與PEL-2004(可容納四模組)，採用模組化設(shè)計(jì)，協(xié)助使用者保留未來可能會(huì)運(yùn)用到更高功率需求的擴(kuò)充性，目前提供4款負(fù)載模組分別為：PEL-2020(200W雙通道負(fù)載模組100W*2 ; PEL-2030 (280W雙通道負(fù)載模組30W+ 250W) ; PEL-2040(350W單通道負(fù)載模組);PEL-2041(350W單通道負(fù)載模組)]，以PEL-2004來代表zui多可以組成8個(gè)通道同步使用，功率範(fàn)圍200W~350W，電流範(fàn)圍0~70A，電壓範(fàn)圍1~500V，使用者可依據(jù)實(shí)際需求，選擇的負(fù)載模組及控制模組進(jìn)行組合或自組負(fù)載系統(tǒng)，可同步執(zhí)行多組電子負(fù)載模組拉載的應(yīng)用，同時(shí)每個(gè)模組採用隔離與地浮接方式，避免造成短路回路 ; 現(xiàn)今綠能產(chǎn)業(yè)蓬勃發(fā)展，PEL-2000 系列符合各式消費(fèi)性電子及車用能源設(shè)備測試的需求，透過外部排線並聯(lián)控制功能，zui多可以同時(shí)控制五個(gè)主機(jī)框，並讓總體的總使用功率達(dá)到7kVA。
PEL-2000系列配備RS232、USB、GPIB(選配)接口、GO/NG接口，同時(shí)還配備了驅(qū)動(dòng)程序和針對(duì)LabView、VB、C、C++等相關(guān)測試軟體範(fàn)例。PEL-2000系列主要應(yīng)用於多通道或單通道輸出的AC/DC電源、DC/DC電源模組、充電器及電源類電子元件性能的測試，對(duì)設(shè)計(jì)研發(fā)、生產(chǎn)線測試及產(chǎn)品檢測作業(yè)上提供快速有效的測試方案，同時(shí)具有的OPP、OCP、OVP、OTP、低壓保護(hù)以及正反向極性保護(hù)功能，更大幅提高了產(chǎn)品的可靠性、是工程測試及自動(dòng)測試環(huán)境得以信賴的產(chǎn)品。
