Coming Soon! Eaton’s modular DC power solutions meet you where you are in your power journey, enabling efficient and cost-effective 50V DC power deployment in busbar-enabled 19" racks while also supporting fully integrated 21” OCP ORV3 racks.
Data center power architectures are shifting toward DC as AI and HPC drive higher rack densities. Eaton’s modular 50V DC solutions deliver rack-level power—scaling from 33 kW to 198 kW per rack—without the complexity of custom or ODM designs.
Mount 19” power shelves and BBU shelves in 21” (OCP ORV3) racks.
Available in 39OU and 44OU sizes with a 600A or 1400A bus bar and 5,000-pound weight capacity, ORV3 racks are offered with or without doors and side panels. Eaton’s reference designs are also fully customizable.
Eaton supports Open Compute Project (OCP) ecosystems, including ORV3 rack and 50V DC power configurations designed to help customers deploy modern architectures with off-the-shelf convenience.
Eaton has expanded its thermal management capabilities through the acquisition Boyd Thermal, strengthening expertise across advanced cooling approaches for higher-density compute environments.
