Keysight EL4913A Regenerative DC Electronic Load

Overview

The Keysight EL4913A is a compact 1U midrange regenerative DC electronic load delivering 2kW of power handling capacity. With a range of 0 to 80V and 0 to 40A, the EL4913A efficiently returns absorbed energy back to the grid, reducing both energy costs and cooling requirements. Engineered for R&D, design validation, and production environments, the EL4913A features built-in voltage and current measurements, multiple I/O interfaces, and system-ready capabilities that accelerate test development.
