New Generation Solutions
DEM Solutions' 800V power protection lineup is purpose-built for the extreme demands of AI training infrastructure like NVIDIA Vera Rubin racks. The 800V CBU (Capacitor Backup Unit) uses supercapacitor technology to absorb microsecond-level surges and GPU inrush current before they reach sensitive hardware, while the 800V Immersion Cooled BBU (Battery Backup Unit) delivers sustained, thermally-managed backup power to bridge the gap until generators or grid power return. Combined into our CBU + Immersion BBU Hybrid Solution, the two work as a single integrated system — instantaneous protection plus sustained backup — in just 1U of additional rack space, delivering 99.999% availability, extending battery life by up to 30%, and paying for itself in as little as 3 months through peak power shaving. Together, they form a complete, plug-and-play power smoothing and backup architecture for next-generation AI data centers.
800V CBU + BBU Hybrid
CBU + Immersion BBU Hybrid Solution for AI data center power racks: pairs microsecond-response supercapacitors with immersion-cooled battery backup to absorb GPU inrush surges, extend cell life by 20-30%, and unlock peak-shaving revenue — all in just 1U of added rack space.
800V CBU
Power Buffer CBU for Vera Rubin Power Rack: a purpose-built 2U supercapacitor module delivering 90 kW of millisecond-level (<150 μs) power buffering to protect Nvidia's next-gen AI racks from GPU inrush surges and grid transients.
800V Immersion BBU
DEM OCP 16OU 800V BBU Shelf: 1.35MW of immersion-cooled battery backup in just 16OU, purpose-built as the instantaneous energy core for Nvidia Vera Rubin AI racks.
