CSU1800AP Series

The CSU1800AP 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.
Model : csu1800ap CRPS

The CSU1800AP power supply is fully digital and compatible with Artesyn Embedded Technologies' 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 CSU1800AP can deliver up to 147.5 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.

This power supply is certified for Platinum Level efficiency, peaking at 94% of efficient power conversion. It also features improved current harmonics (iTHD) at light loads.
