EA-ELR 10750-40 3U Programmable DC Electronic Load with Energy Recovery

The EA-ELR 10750-40 3U is a high-performance programmable DC electronic load designed for rigorous testing applications, featuring advanced energy recovery technology that feeds up to 95.5% of consumed power back into the AC grid—making it an efficient and eco-friendly solution for power supply testing, solar panel simulation, and battery validation. With a wide voltage range of 0-750V, maximum current of 40A, and power rating of 10000W (under 380-480V AC input), this regenerative load system supports constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR) modes. It includes a built-in function generator for creating dynamic test profiles (sine, triangle, rectangle, trapezoid, DIN 40839, arbitrary, ramp, XY table), MPP tracking for solar inverter testing, and battery test functions for charge/discharge cycles. The unit offers multiple remote control options (USB, Ethernet, analog interface), master-slave parallel operation for scaling up to 64 units, and complies with international safety standards (EN 61010-1). Ideal for laboratory, industrial burn-in, and R&D environments, the EA-ELR 10750-40 3U ensures precise, reliable, and energy-efficient DC power testing.
