EL4945A

Regenerative DC Electronic Load 500V, 72A, 12,000W, In 3ph

The EL4945A from the Keysight EL4900 Series of midrange regenerative DC electronic loads. These single-input, programmable loads provide precision for power device testing, from validation to transient analysis. The regenerative feature returns up to 95% of absorbed energy to the grid, reducing energy and cooling costs without disrupting grid performance. Paired with the PathWave Advanced Power Suite software, the EL4900 Series provides robust automation of complex test scenarios, letting you validate complex power devices in less space with no compromise on performance or programmability.
