OCP ORv3 Rack Power Distribution Busbar

OCP ORv3 Rack Power Distribution Busbar

RHI Rack Busbars are designed for OCP ORv3 Open Rack systems and high-density AI data centers, providing standardized high-current DC power distribution through a laminated busbar structure. With current ratings ranging from 425A to 2900A, they support diverse power requirements for Power Shelves, PSU modules, BBU systems, AI servers, storage, and network switches. Blind-mate connections simplify installation, reduce cabling complexity and voltage drop, while the vertical busbar design helps reduce cable congestion, improve airflow, and simplify rack maintenance. Custom designs are available to meet specific rack configurations and power requirements.
