Overview
Acbel's high-density power portfolio targets the move to high-voltage DC power in AI data centers. The flagship 100kW Power Shelf delivers 100kW of output in a compact 1OU form factor and, combined with Acbel's patented PDU design, can be configured for either ±400V or 800V DC output to match different data-center power architectures.
For 50V architectures Acbel offers a 19-inch 72kW Power Shelf built from 12kW modules rated to 102 W/in³ and certified to 80 PLUS Ruby — the top efficiency tier — for increasingly power-intensive AI infrastructure. Acbel also integrates the shelves into a 1MW HVDC cabinet with backup battery unit (BBU) shelves.
The shift to HVDC reduces conversion losses, improves PUE and simplifies thermal design compared with traditional 50V distribution. Acbel is also developing liquid-cooled power technologies to handle rising rack densities, and is showcasing the portfolio alongside subsidiary OmniOn Power at the OCP Global Summit 2026.
Key Benefits
Megawatt-ready power density for AI racks. The 100kW 1OU shelf supports 800V / ±400V HVDC, and the 72kW 50V shelf uses 12kW modules at up to 102 W/in³ with 80 PLUS Ruby efficiency. HVDC lowers conversion losses, improves PUE and simplifies thermal design as racks scale toward megawatt class.
Applications
AI and HPC data-center power distribution; hyperscale and cloud racks; OCP-style open-rack deployments; 800V / ±400V HVDC facility architectures; high-density GPU rack power; backup-battery-integrated power cabinets.
