Advanced Energy introduced a high-density, high-efficiency 48 V, 30 kW dual-feed Open Rack version 3 (ORv3) power shelf that minimizes the power consumption and improves the reliability of computing and storage applications in hyperscale and enterprise data centers.
Featuring power supplies with demonstrated efficiency of 97%, Advanced Energy’s new Artesyn 2U shelf incorporates a hot-swappable controller and can accommodate up to twelve 48 V, 3 kW open rack rectifiers with power up to 30 kW. These rectifiers include an embedded automatic transfer switch (ATS) capability that switches the input to a secondary AC source on detection of primary AC power loss without any interruption to the output voltage.
Advanced Energy’s ORv3 30 kW power shelf is compatible with star, delta, and single-phase input configurations and includes a hot-pluggable, DMTF Redfish-compatible Shelf Controller for simple, secure monitoring and control over Ethernet. Its 48 V, 3 kW rectifiers are Highline single-phase AC-DC power supplies that convert input voltages of between 200 Vac and 277 Vac into 48 V output. A narrow output voltage band eliminates oversize design and enables a 4:1 ratio DC-DC conversion for downstream 12 V loads.
Both the power shelf and the rectifiers are fully compliant with EN61000-4-5 and EN55035 EMC standards and IEC/UL/EN62368 safety standards.
The power shelf will be showcased at AE’s booth C22 at the Open Compute Project (OCP) Global Summit 2021, which takes place November 9-10 at the San Jose McEnery Convention Center.
