Keysight EL4943A Regenerative DC Electronic Load

Overview

The Keysight EL4943A is a compact 2U regenerative electronic load with a single input rated 0–80V, 0–240A, and up to 12kW. Its regenerative design efficiently returns up to 95% of absorbed energy back to the grid, reducing energy costs and cooling requirements. Engineered for R&D, design validation, and production environments, the EL4943A delivers reliable performance in a space-saving form factor with low cost of ownership.
