PEL-2000可编程直流电子負載，此電子負載可以工作在定電流、定電壓、定電阻模式下，還可模擬各種動態負載狀況，透過序列功能進行負載電壓、電流、負載的上升及下降斜率、電流準位、持續時間等参數來编輯負載波形，，同時提供外部波形信号控制以及V&I監測功能，測試參數及狀態的存儲可高達120组，系统可根據自動測試需求，隨時由儀器内部的儲存單元EEPROM中呼叫出来使用。
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)，採用模组化設計，協助使用者保留未來可能會運用到更高功率需求的擴充性，目前提供4款負載模组分別為：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來代表最多可以组成8个通道同步使用，，功率範圍200W~350W，，電流範圍0~70A，電壓範圍1~500V，，使用者可依據實際需求，，選擇的負載模组及控制模组進行组合或自组負載系统，，可同步執行多组电子負載模组拉載的應用，同時每個模组採用隔離與地浮接方式，，避免造成短路回路 ; 現今綠能產業蓬勃發展，，PEL-2000 系列符合各式消費性電子及車用能源設備測試的需求，，透過外部排線並聯控制功能，最多可以同時控制五個主機框，，並讓總体的總使用功率達到7kVA。
PEL-2000系列配備RS232、USB、GPIB(選配)接口、GO/NG接口，同时還配備了驅動程序和針對LabView、VB、C、C++等相關測試軟體範例。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、充电器及电源類电子元件性能的測試，對設計研發、生產線測試及產品檢測作業上提供快速有效的測試方案，同時具有的OPP、OCP、OVP、OTP、低壓保護以及正反向極性保護功能，更大幅提高了產品的可靠性、是工程測試及自動測試環境得以信賴的產品。
