Power-One, a renewable energy and energy-efficient power conversion and power management solutions provider, has released a 450W and 700W high efficiency power supply/battery back-up unit for next generation, high efficiency servers and data centres.
The SPAFCBK-02G (450W) and SPAFCBK-03G (700W) were designed based on the Open Compute Project specifications. They feature a platinum efficiency rated AC-DC power supply with a 48V dc battery back-up circuit in one compact design.
Power-One states that both versions have over a 94% efficiency and power supply certification of 80-plus platinum level efficiency. The technologies operate from a 277Vac input voltage source, allowing the server to be powered directly from one-phase of the high voltage 3-phase input power distribution network.
