How can engineers test power systems built for rapidly changing AI workloads without wasting the energy absorbed during testing? A regenerative platform offers one approach.
Tektronix has launched the EA-ELR 21000 Dynamic Test System to help validate high voltage DC power systems being designed for AI data centres. It can measure 800V DC power distribution systems such as power shelves, power racks and solid state transforms where dynamic computing demands can create challenging loads.
At the core of the system is an electronic load module that uses regenerative technology to simulate dynamic loads. The EA-ELR 21000-80 4U HS can provide up to 1000V, 80A and 30kW. By drawing power from the device under test, it can efficiently return up to 95% of this to the grid as opposed to traditional electronic loads that waste this energy as heat. This can reduce heat generation in long testing periods.
The system can dynamically change loads quickly with current slews of 12A/µs, at 240kW. Engineers can use this to test power shelves and racks and see how they behave when there are sudden changes in power due to AI demands. This can be useful to determine how stable, efficient and reliable the system is.
The modular design allows you to expand your testing capabilities. Each rack provides 240kW but can be expanded in 30kW increments. By using multiple racks, you can create a system to provide up to 1.92MW in 8 racks and 64 loads. You can also service individual modules.
