Feature

Murata Manufacturing’s power shelves for centralized power supply systems integrate and house high-efficiency power supply units (PSUs) and remote management units (RMUs) to improve the operational efficiency of data centers and AI servers.

We offer a lineup of power shelves that can be installed in EIA racks with a width of 19 inches that are widely used in conventional data centers in addition to the standard OCP rack width of 21 inches. Therefore, our power shelves can be installed in a wide range of operating environments from existing infrastructure to the latest configurations.

Our power shelves are also compatible with diverse input methods. It is possible to use both AC (three-phase Wye, Delta and single-phase) and DC input. Moreover, the power shelves have two input connectors. Therefore, it is possible to use the redundant configurations of N+1 (M) for general PSU redundancy as well as N+N for input system redundancy. Furthermore, to address the increasing power consumption per rack due to an increase in the thermal design power of xPUs in recent years, the ORV3 system and later support parallel operation of power shelves.

Adoption Benefits and Advantages

  • Wide-ranging installation conformity: Compatible with both 21-inch OCP specifications and 19-inch EIA specifications
  • Compatibility with diverse inputs: All AC input methods and DC input
  • Support for various redundancy designs: Compatible with N+1 (M) for PSU redundancy and N+N for input redundancy
  • Compatible with high loads: Also compatible with higher power densities in racks with parallel operation support
