CSU1800AP Series


1800 W CRPS-Type Power Supply

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. The CSU1800AP 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. The main 12 VDC output delivers up to 3.5 A while the 12 VDC standby output delivers up to 147.5 A.
