Keysight EL4935A Regenerative DC Electronic Load

Overview

The Keysight EL4935A is a 1U regenerative DC electronic load with voltage range 0–500V, current range 0–36A, and 6kW power rating. Its regenerative design returns up to 95% of absorbed energy back to the grid, reducing energy costs and cooling requirements. Built-in voltage and current measurements, multiple I/O interfaces, and system-ready capabilities make it suitable for R&D, design validation, and production testing.
