Power-One’s High Efficiency Power Supply with Integrated Battery Back-up Circuit Targeted for Next Generation Open Compute Servers and Data Centers

Camarillo, CA – December 6, 2012 – Power-One, Inc. (NASDAQ: PWER), a leading provider of renewable energy and energy-efficient power conversion and power management solutions, has released 450W and 700W High Efficiency Power Supply/Battery Back-up unitsfor use in next generation, high efficiency servers and data centers. The Power-One power supplies, SPAFCBK-02G (450W) and SPAFCBK-03G (700W), have been designed based on the Open Compute Project specifications.
 
The power supplies combine a 450W or 700W Platinum Efficiency rated AC-DC power supply with a 48Vdc battery back- up circuit, all in one compact design. Both versions are highly efficient (over 94% efficiency) and the power supply has been certified to 80-Plus Platinum level efficiency. They operate from a 277Vac input voltage source which allows the server to be powered directly from one-phase of the high voltage 3-phase input power distribution network.  Designing the power supply for 277Vac per the Open Compute Project specifications eliminates an expensive site transformer, and is critical to the goal of increasing the power efficiency and reducing the overall carbon footprint of the data center.
 
With the power supply designed at better than 94% efficiency, less energy is wasted within the server, and less energy is consumed in the overall cooling infrastructure.  The integrated 48V battery back-up circuit eliminates the need for inefficient UPS systems and allows for a localized, scalable power back-up infrastructure.
 
“This was a very technically challenging product due to the high efficiency target andthe complexity of the power supply/battery back-up design. The power supply is a crucial building block for the next generation of highly efficient servers and data centers.  Power-One was the first in the industry to release such a product and we have followed that lead with these latest power supply offerings”, said Helio Sakaya, Vice President of Marketing and Product Management for Power-One.
