High-Power, High-Density Regenerative DC Electronic Loads 
the Keysight EL4900 Series of midrange regenerative electronic loads. These single-input, programmable loads are available in compact 1U and 2U sizes, with power ratings from 2 kW to 12 kW. With regenerative capabilities, they efficiently return absorbed energy to the grid, reducing energy costs and minimizing cooling needs.  
The EL4900 Series includes system-ready features such as multiple I/O interfaces, built-in voltage and current measurements, and operating ranges of 80 V to 800 V and 8 A to 240 A, enabling faster test development and reliable evaluation in R&D, design validation, and production environments.
