EA-ELR 12000-20 3U Programmable DC Electronic Load with Energy Recovery

The EA-ELR 12000-20 3U is a high-voltage, energy-recovering programmable DC electronic load designed for rigorous testing of power sources and components. With a maximum voltage of 2000V, current of 20A, and power handling up to 15000W (derated to 9000W at 208V AC input), this unit offers exceptional performance for demanding applications. It achieves up to 95.5% efficiency by feeding recovered energy back into the local grid, reducing operational costs. The load supports constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR) modes, with a resistance range from 3.5Ω to 5300Ω and an input capacitance of 60µF. Integrated protections include overvoltage (OVP), overcurrent (OCP), and overpower (OPP) safeguards, ensuring reliable operation. Ideal for photovoltaic inverter testing, electric vehicle power system validation, high-power component aging, and grid simulation, the EA-ELR 12000-20 3U combines precision, safety, and energy efficiency in a robust 3U chassis.
