EA-ELR 21000

The ELR 21000 dynamic test system is a modular, high-speed regenerative electronic load platform designed for testing and validating modern data center power systems

Built for emerging 800 VDC architectures, it helps engineers emulate the rapid power transients generated by AI processors, GPUs, and high-performance computing workloads.

With current slew rates up to 12 A/μs at 240 kW and scalable power up to 1.92 MW, the system enables realistic validation of power shelves, sidecar converters, and rack-level power infrastructure.

Regenerative operation returns absorbed energy back to the grid at up to 95% efficiency, significantly reducing energy consumption, heat generation, and cooling requirements compared to conventional load solutions. The result is accurate dynamic testing, lower operating costs, and a scalable path for next-generation data center power validation.

Key Features:

• Up to 1.92 MW total system power
• 0 to 1000 VDC operating range
• Up to 5120 A total system current
• Current slew rates up to 12 A/μs at 240 kW
