CSU550AP Series


550 W CRPS-Type Power Supply

The CSU550AP 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. This form factor conforms to the standard market's Common Redundant Power Supplies. The CSU550AP power supply is fully digital and compatible with Advanced Energy's universal PMBus® graphical user interface, allowing control via an integral I2C interface using the industry-standard PMBus communications protocol.
