Delta, a global leader 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 OCP Global Summit in San Jose, California,
USA. 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.

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. 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.”

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. 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.

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.
