能量回饋式電子負(fù)載 EA-ELR 9000 3U 系列 | Electronic Load with Energy Recovery EA-ELR 9000 3U Series

此款由微處理器控制的高性能電子負(fù)載系列產(chǎn)品，具有研發(fā)和工業(yè)測試環(huán)境所需的所有典型功能。專為組件與產(chǎn)品測試而設(shè)計，如：半導(dǎo)體，模擬和數(shù)字電路，電源，電容，電池，燃料電池等的測試。提供所有關(guān)鍵操作模式，如：恒壓，恒流，恒功率和恒阻（CV, CC, CP, CR），使得本系列為自動測試臺和老化室使用的理想工具。而且，EA-ELR 9000系列還有一項*的現(xiàn)代化功能，即帶能量返回式逆變器功能。

測試過程中從直流源處提取的能量可被轉(zhuǎn)化成AC 20/230/240V 50/60 Hz。這個能量回饋到本地市電電網(wǎng)。并將交流電供給電網(wǎng)的其它設(shè)備。它的轉(zhuǎn)換效率>90%, 所以不會像普通電子負(fù)載一樣工作時產(chǎn)生100%的熱消散。還具有超快反應(yīng)時間(<50 μs)，高系統(tǒng)靈活度和度，并提供模擬和數(shù)字接口控制設(shè)備，如基板上有標(biāo)準(zhǔn)的0-10V和USB接口，還有RS232，CAN，Ethernet, Profibus可選。從而使本產(chǎn)品成為測試環(huán)境下的多用途和節(jié)能工具。帶圖形顯示器和控制軟件的易操作人機界面（觸摸屏）可進(jìn)行自動測試（排序/數(shù)據(jù)記錄）。

This high-performance μ-processor controlled electronic load series features all necessary functions typically required in demanding R&D and industrial testing environment. They are designed for the testing of components and devices such as semiconductors, analogue and digital circuits, power-supplies, capacitors, batteries, fuel cells etc. All crucial operation modes i.e. constant voltage-, current, -power and resistance (CV, CC, CP, CR) are provided, making this series and ideal tool for automated test benches and burn-in facilities. Moreover, EA-ELR 9000 series features a unique state-of-the-art inverter function with energy recovery.

The energy extracted from the DC source under testing is inverted and mains synchronised into AC 20/230/240V 50/60 Hz and this energy then feed back into the local mains power grid, enabling to supply AC power to djacent equipment on the grid. With an inverter efficiency of >90%, the enormous heat dissipation of 100% typically found at conventional electronics load is therefore almost eliminated. An ultra-fast response time (<50 μs), high system flexibility and precision, analogue and digital interface control facilities such as standard 0-10V and USB on board and RS232, CAN, Ethernet, Profibus optionally, make this series an extremely versatile and energy-efficient tool in testing environment. An easy-to-operate human interface (touch panel) with high-end graphic display and control software (optional) for automated testing (sequencing/ data logging) are provided.
