CSU2400AT Titanium Efficiency Series

The CSU2400AT titanium efficiency power supply is housed in a 1U high rack-mount enclosure measuring just 2.89 x 7.28 inches (73.5 x 185.0 mm). This form factor is significantly narrower and shorter than that of similarly rated earlier generation power supplies — freeing up valuable system space — and is achieved by use of the latest power switching technology and high density component packaging techniques. This form factor conforms to the standard market’s Common Redundant Power Supplies. This is also mechanically compatible to the platinum efficiency rated CSU2400AP, making it suitable as an upgrade path for systems that require titanium efficiency.

The CSU2400AT power supply is fully digital and compatible with Artesyn Embedded Power’ universal PMBus™ graphical user interface, allowing control via an integral I2C interface using the industry-standard PMBus communications protocol. Each power supply 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 3.5 A can be used for power management or supervisory circuitry. The main DC output of the CSU2400AT can deliver up to 196.7 A. Active current sharing helps maximize cost-effectiveness by eliminating the need for additional components when paralleling multiple power supplies for very high current applications.

The power supply is certified for Titanium Level efficiency, peaking at 96% of efficient power conversion. It also features improved current harmonics (iTHD) at light loads.
