PEL-2000可編程直流電子負載，，此電子負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)負載狀況，透過(guò)序列功能進(jìn)行負載電壓、電流、負載的上升及下降斜率、電流準位、持續時(shí)間等參數來(lái)編輯負載波形，同時(shí)提供外部波形信號控制以及V&I監測功能，測試參數及狀態(tài)的存儲可高達120組，，系統可根據自動(dòng)測試需求，隨時(shí)由儀器內部的儲存單元EEPROM中呼叫出來(lái)使用。
PEL-2000系列包含兩種主控含機框PEL-2002(可容納雙模組)與PEL-2004(可容納四模組)，，採用模組化設計，，協(xié)助使用者保留未來(lái)可能會(huì )運用到更高功率需求的擴充性，目前提供4款負載模組分別為：PEL-2020(200W雙通道負載模組100W*2 ; PEL-2030 (280W雙通道負載模組30W+ 250W) ; PEL-2040(350W單通道負載模組);PEL-2041(350W單通道負載模組)]，以PEL-2004來(lái)代表最多可以組成8個(gè)通道同步使用，功率範圍200W~350W，電流範圍0~70A，，電壓範圍1~500V，，使用者可依據實(shí)際需求，，選擇的負載模組及控制模組進(jìn)行組合或自組負載系統，，可同步執行多組電子負載模組拉載的應用，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 ; 現今綠能產(chǎn)業(yè)蓬勃發(fā)展，PEL-2000 系列符合各式消費性電子及車(chē)用能源設備測試的需求，透過(guò)外部排線(xiàn)並聯(lián)控制功能，最多可以同時(shí)控制五個(gè)主機框，並讓總體的總使用功率達到7kVA。
PEL-2000系列配備RS232、USB、GPIB(選配)接口、GO/NG接口，同時(shí)還配備了驅動(dòng)程序和針對LabView、VB、C、C++等相關(guān)測試軟體範例。PEL-2000系列主要應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(lèi)電子元件性能的測試，對設計研發(fā)、生產(chǎn)線(xiàn)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、低壓保護以及正反向極性保護功能，，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(lài)的產(chǎn)品。
