能量回馈式电子负载 EA-ELR 9000 3U 系列 | Electronic Load with Energy Recovery EA-ELR 9000 3U Series

此款由微处理器控制的高性能电子负载系列产品，具有研发和工业测试环境所需的所有典型功能。专为组件与产品测试而设计，如：半导体，模拟和数字电路，电源，电容，电池，燃料电池等的测试。提供所有关键操作模式，如：恒压，恒流，恒功率和恒阻（CV, CC, CP, CR），使得本系列为自动测试台和老化室使用的理想工具。而且，EA-ELR 9000系列还有一项*的现代化功能，即带能量返回式逆变器功能。

测试过程中从直流源处提取的能量可被转化成AC 20/230/240V 50/60 Hz。这个能量回馈到本地市电电网。并将交流电供给电网的其它设备。它的转换效率>90%, 所以不会像普通电子负载一样工作时产生100%的热消散。还具有超快反应时间(<50 μs)，高系统灵活度和度，并提供模拟和数字接口控制设备，如基板上有标准的0-10V和USB接口，还有RS232，CAN，Ethernet, Profibus可选。从而使本产品成为测试环境下的多用途和节能工具。带图形显示器和控制软件的易操作人机界面（触摸屏）可进行自动测试（排序/数据记录）。

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.
