1100W front-end DC supplies offer high power density

CUI has announced an addition to its line of 1100W 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 40x54.5x321.3mm. The narrow profile allows designers to minimise application space compared to larger solutions on the market.

The power supply outputs 12VDC with 5 or 3.3VDC 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 40-72VDC, 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 suited for telecomms, server and networking rack mount applications where a mix of AC 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 12VDC output delivers up to 92A 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. Samples are available immediately.
