Artesyn Embedded Technologies has developed an 800W server power supply that follows the Intel Common Redundant Power Supply (CRPS) specification. The CSU800AP is designed for compute, networking and storage infrastructure in enterprise IT, cloud and hyperscale environments.
The CSU800AP is housed in a compact, 1U high enclosure measuring just 2.89 x 7.28-inch (73.5 x 185.0mm). This, says Artesyn, is a significantly smaller footprint than that of similarly rated, earlier generation power supplies. The form factor is achieved by using the latest power switching technology and high density component packaging techniques.
This power supply features a wide input range of 90 to 264V AC, active power factor correction and is certified for 80plus platinum rated efficiency peaking at 94 per cent. It also features improved current harmonics (iTHD) at light loads.
The CSU800AP generates a main output of 12V DC for feeding downstream DC/DC converters in systems using distributed power architectures. A 12V DC standby output rated at 3.0A can be used for power management or supervisory circuitry.
The main DC output of the CSU800AP can deliver up to 66.7A continuously and with peak-pulsed capability of up to 93.3A. Active current sharing helps maximise cost effectiveness, explains Artesyn, by eliminating the need for additional components when paralleling multiple power supplies for high current applications.
The CSU800AP power supply is hot-pluggable and compatible with the Artesyn Embedded Technologies universal PMBus graphical user interface (GUI), allowing control via an integral I2C interface using the industry-standard PMBus communications protocol.
Artesyn Embedded Technologies designs and manufactures reliable power conversion and embedded computing solutions for a wide range of industries including communications, computing, consumer electronics, medical, military, aerospace and industrial automation. Headquartered in Tempe, Arizona, Artesyn has over 16,000 employees worldwide across 10 engineering centres of excellence, four wholly-owned world-class manufacturing facilities, and global sales and support offices.
