Description

ELR21000-804U-HS | Regenerative Electronic DC Load, 1000 V, 80 A, 30 kW

The ELR21000-804U-HS is a highly dynamic, energy-recovery-capable electronic load designed for demanding high-voltage testing applications. It is designed for voltages up to 1000 V and is specifically optimized for operation on 800-V systems. With a power rating of up to 30 kW and a current range up to 80 A, it is particularly well-suited for applications where rapid load changes need to be realistically simulated and the dynamic behavior of modern power electronics needs to be investigated.

Typical applications include the development and testing of 800-V power shelves and power racks in data centers, as well as solid-state transformers and other high-power AC/DC and DC/DC converters. The focus here includes, among other things, the analysis of transient behavior and system stability, efficiency measurements, as well as burn-in, lifespan, and endurance tests. High current rise rates are particularly critical in modern AI and data center applications, as CPU and GPU loads can vary significantly within a very short time.

A key advantage of the ELR21000-804U-HS is its regenerative operation: The electrical energy absorbed is not primarily converted into heat, but can be fed back into the grid or reused within the test system. This reduces energy consumption, heat generation, and cooling requirements in the laboratory. The ELR21000-804U-HS also serves as a modular component of the scalable ELR-21000 Dynamic Test System.
