Delta, a global pioneer in power and thermal management solutions, announces the launch of its latest Open Rack version 3 (ORV3) 1 OU 18 kW power shelves at the 2023 OCP Global Summit in San Jose, California, USA.

6-slot-chassis power shelf

The high-efficiency 6-slot-chassis power shelf is specifically designed to enable substantial energy savings in AI servers.

It includes Delta’s new 3kW power supply units (PSU), which boast over 97.5% peak efficiency and can integrate the power management controller (PMC), with industry-leading PoE (Power over Ethernet) function, to enable smart power management in AI data centers.

Scalability and efficiency

We have embraced ORV3 standards and leveraged Delta’s 50-year prowess in energy-efficient power solutions"

Ares Chen, General Manager of Delta’s Power and System Business Group, said, “As AI, 5G, automation, and other advanced technologies are becoming driving forces in the server market, more and more clients are adopting the third generation of Open Rack to meet higher power demands."

Ares Chen adds, "We have embraced ORV3 standards and leveraged Delta’s 50-year prowess in energy-efficient power solutions, to develop new power shelves that offer high scalability and efficiency for a wide range of applications, including hyper-scale data centers.

addresses higher power density

Delta’s 18 kW power shelf conforms to the Open Rack Standard V 3.0 busbar definition to address higher power density needs.

It provides 48 / 50 VDC output voltage rather than the traditional 12 VDC to reduce electricity distribution losses. 

secure monitoring and control

The power shelf is scalable with extensive options for communication protocols

The power shelf offers a maximum 18 kW power output or 15 kW with 5+1 redundancy which accommodates six 3 kW hot-pluggable power supply units. Each unit has a 150% load capability for 20 milliseconds to ensure protection from sudden current increases.

The power shelf is scalable with extensive options of communication protocols such as PMBus over I2C and RS485 for secure monitoring and control.

PMC with PoE function

Another highlight is the PMC with PoE function, which provides up to 1GbE Ethernet and allows PMC to work with the ORV3 power shelf for energy saving and optimal operational performance of data centers.

In addition, both the power shelf and PMC can be customized in terms of hardware and firmware based on client demands to realize high energy efficiency for data centers.
