1100 W Front-End Power Supply Series Expanded to Include Dc Input Versions



TUALATIN, Ore. – CUI Inc today announced an addition to its line of 1100 W front-end power supplies to include dc input versions.  The PSD-1100-12 series delivers high power density and achieves Platinum efficiency in a compact slim line 1U package measuring just 1.575 x 2.145 x 12.65 inches (40 x 54.5 x 321.3 mm). The narrow 54 mm profile allows designers to minimize application space compared to larger solutions on the market.  The power supply outputs 12 Vdc with 5 Vdc or 3.3 Vdc pin-selectable standby. The PSD-1100-12 is hot pluggable with a dc input connector at the front and an industry standard output connector that integrates dc power and signal pins at the back. With an input range of 40~72 Vdc, the unit is designed to be compatible with CUI’s existing ac input PSA-1100-12, allowing plug and play operation between the two versions.  The series is ideally suited for telecom, server and networking rack mount applications where a mix of ac input and dc input versions are required.



The PSD-1100-12 features system communications via I2C/PMBus™ protocol for control and monitoring of the unit. The main 12 Vdc output delivers up to 92 A with droop current sharing for paralleling multiple units; forced current sharing is optional. For maximum flexibility, the series is available in front-to-back or back-to-front airflow configurations depending on the application’s cooling requirements. The PSD-1100-12 also offers 60950-1 safety approvals, bears the CE Mark, and complies with all applicable EMC requirements to accommodate world wide applications. Protections for over-voltage, over-current, over-temperature, and input under-voltage are standard.
