Housed in a compact 1U high enclosure measuring just 2.89 x 7.28 inches (73.5 x 185.0 mm), the CSU550AP has a significantly smaller footprint than that of similarly rated earlier generation power supplies and, according to Artesyn, has been achieved by using the latest power switching technology as well as high density component packaging techniques.
This power supply features a wide input range of 90-264 Vac, active power factor correction and is certified for 80plus platinum rated efficiency peaking at 94 percent.
The CSU550AP generates a main output of 12 Vdc for feeding downstream dc-dc converters in systems using distributed power architectures. A 12 Vdc standby output rated at 3 A can be used for power management or supervisory circuitry. The main DC output of the CSU550AP can deliver up to 45.8 A. 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 + 6 dB margin conducted/radiated EMI and RoHS certification.
