UL Greenlights Data Center Hardware

CUI Inc. has successfully received UL 9540 certification for its Intelligent Control of Energy (ICE) Block technology. The ICE Block, employing lithium-ion battery storage, shaves peaks by supplying power for peak load events and automatically recaptures power during low utilization periods. When paired with partner Virtual Power Systems' ICE software, the ICE Block hardware and ICE software combine to deliver more power within data centers by reshaping it as a resource, resulting in lower operating costs and less redundant power supply capacity.


UL 9540 requirements cover energy storage systems and equipment that are intended to receive, store, and provide electric energy to applications. They also cover several sub-standards, including UL 1741 for inverters, UL 1998 and UL 991 for functional safety, and UL 1973 for battery control modules. For more information visit CUI.
