EA-ELR 11000-40 3U Programmable Electronic DC Load with Energy Recovery

The EA-ELR 11000-40 3U is a high-performance programmable electronic DC load designed for energy recovery applications, capable of converting up to 95.5% of consumed DC energy back to the local grid; this 1000V, 40A, 15000W electronic load supports constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR) operating modes, includes an integrated function generator for generating sine, triangle, rectangle, trapezoid, DIN 40839, arbitrary, ramp, and XY table waveforms, and offers advanced testing functions such as battery testing and MPP tracking for solar panel simulation; with its regenerative capability, it significantly reduces energy consumption and operating costs, while providing precise control and real-time monitoring via a 5-inch color TFT touchscreen, multiple communication interfaces (USB, Ethernet, analog, and optional digital modules), and support for master-slave parallel operation with up to 64 units for scalable power requirements.
