EA-ELR 10080-340 3U Programmable Electronic DC Load with Energy Recovery

The EA-ELR 10080-340 3U is a high-performance programmable electronic DC load from the ELR 10000 Series, designed for sophisticated DC load testing, power supply testing, battery testing, and solar panel testing applications. As an Electronic Load Recovery unit, it features advanced energy recuperation technology, feeding up to 94.5% of the absorbed DC energy back into the local grid with high efficiency. With a wide voltage range of 0-80V and a high current capability of 0-340A, it delivers a maximum power of 10,000W (15,000W for 3U models on 400V AC input, derated to 6,000W on 208V AC). It offers versatile operating modes including constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR), and is equipped with a built-in function generator for creating complex test profiles like sine, triangle, rectangle, trapezoid, and arbitrary waveforms, as well as dedicated battery test and MPP tracking functions for photovoltaic panel simulation. The device supports master-slave parallel operation for scaling up to 960kW systems, and provides multiple remote control interfaces including USB, Ethernet, analog, and optional plug-in modules for CAN, Profibus, Profinet, ModBus TCP, and more, making it an ideal and energy-efficient solution for laboratory, industrial, and automotive component testing.
