A 550W server power supply has been announced by Artesyn Embedded Technologies. It follows the Intel Common Redundant Power Supply (CRPS) specification which is designed for hyper-converged compute, networking and storage infrastructure in enterprise IT and cloud environments.
The CSU550AP is housed in a compact 1U high enclosure measuring 73.5x185mm which is achieved by using power switching technology and high density component packaging techniques.
This power supply features a wide input range of 90-264Vac, active power factor correction and is certified for 80 PLUS platinum rated efficiency peaking at 94%. The CSU550AP generates a main output of 12Vdc for feeding downstream DC/DC converters in systems using distributed power architectures. A 12Vdc standby output rated at 3A can be used for power management or supervisory circuitry. The main DC output of the CSU550AP can deliver up to 45.8A. Active current sharing helps maximize cost effectiveness by eliminating the need for additional components when paralleling multiple power supplies for high current applications.
The CSU550AP power supply is hot pluggable and compatible with the Artesyn Embedded Technologies universal PMBus graphical user interface, allowing control via an integral I2C interface using the industry-standard PMBus communications protocol with Class A + 6dB margin conducted/radiated EMI and RoHS certification.
