EA-ELR 10080-510 3U Programmable Electronic DC Load with Energy Recovery

The EA-ELR 10080-510 3U is a high-power, programmable electronic DC load designed for demanding industrial and laboratory testing applications. Part of the advanced ELR 10000 Series, this model stands out with its exceptional current handling capability of 0-510A and a wide voltage range of 0-80V, enabling a maximum power dissipation of 15,000W. Its defining feature is the integrated energy recovery system, which converts up to 94.5% of the absorbed DC power and feeds it back into the local AC grid, dramatically reducing energy costs and heat generation. The load operates on a three-phase AC input (380-480V ±10%) for full performance, with an automatic derating to 9,000W when used on a 208V AC supply. It supports all standard operating modes—Constant Current (CC), Constant Voltage (CV), Constant Power (CP), and Constant Resistance (CR)—and is equipped with a sophisticated function generator for creating complex test sequences like sine, triangle, and arbitrary waves, including simulations per DIN 40839 for automotive testing. Dedicated functions for Battery Testing (static and dynamic discharge) and MPP Tracking for solar panel characterization make it incredibly versatile. With support for master-slave parallel operation of up to 64 units and a comprehensive suite of interfaces (USB, Ethernet, Analog, and optional plug-in modules for CAN, Profibus, etc.), the EA-ELR 10080-510 3U is an efficient and powerful solution for validating power supplies, testing batteries, performing component burn-in, and simulating real-world load conditions.
