CUI Introduces 54 mm 1U Series Featuring N+1 Redundancy and PMBus(TM) Communication

1100 W Hot-Swap Front-End Power Supply Minimizes Application Space

TUALATIN, Ore. – CUI Inc today announced the introduction of a 1100 W front-end ac-dc power supply for mission critical (N+1) redundant applications. The PSA-1100-12 delivers a power density of 25.34 W/cubic inch and achieves efficiencies approaching 94% 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 PSA-1100-12 is hot pluggable with an IEC320 ac connector at the front and an industry standard output connector that integrates dc power and signal pins at the back. The unit is ideally suited for telecom, server and networking rack mount applications where reliability, power density, and energy consumption are key considerations.

The PSA-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 PSA-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.

Engineering samples are available immediately; please contact CUI for more information.
