15kW data centre power shelf has 97% efficiency
Advanced Energy Industries has launched a 15kW AC-DC power shelf to support to move to 48V supplies in data centres.
The AE Artesyn 21in rack unit is fully compatible with the Open Compute Project (OCP) Open Rack version 3 (ORv3) standard to support the evolution to 48 V rack power architectures for lower power consumption.
Offering 15 kW N+1 redundancy with peak efficiencies of over 97%, the new power shelf can be supplied with single or dual AC power inlets. It accommodates up to six 3 kW hot-swappable single-phase AC-DC power supplies and a removeable shelf controller. Each power supply can deliver a 50.5 V, 60 A output and accepts an input of 180 to 305 Vac. A narrow output voltage range eliminates oversized design and simplifies downstream conversion to lower voltages.

The 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. A Modbus/PMBus communications interface is also provided for monitoring and control.
“This new power shelf addresses the need to increase rack payload and power density, minimize energy consumption and ensure compatibility across leading data center hardware by moving to interoperable power conversion solutions,” said Harry Soin, Advanced Energy’s senior director of technical marketing for hyperscale data centres. “In addition, hot swappable functionality and the option of a secondary power source increase overall system reliability.”
The rectifiers offer active power factor correction (PFC) to achieve ultra-low harmonic currents in accordance with EN/IEC 61000-3-2 and EN 60555-2. They incorporate protection against overvoltage, overcurrent, undervoltage and over-temperature conditions. Internally controlled, variable speed fans reduce power consumption by accurately matching the cooling required for power supply operating conditions.
Advanced Energy is a longstanding contributor to the OCP ORv3 standard and a leading enabler of 48 V rack power. The launch of the AE ORv3-compliant power shelf marks another milestone in the company’s contribution to the transition to 48 V architecture.
