    September 2008, Mansfield, Massachusetts
    Murata Power Solutions has introduced a new family of AC/DC Front End power supplies that deliver bulk power with high efficiency of up to 90.9% and high power density up to 17.9W/in.³ The new units are ideal for use in servers, network equipment and other distributed power architecture applications. The D1U4-W series is housed in a 1U low-profile package and is offered with output power of 1600 W (220VAC) or 1200W (110VAC) and main output voltages of 12V.
     
    The D1U4-W series has active power factor correction and features active current sharing on its main output. Integrated OR-ing FETs support N+1 operation including hot docking. In addition to the main output, standby outputs of either 3.3V or 5V that give up to 20W of standby power are provided to support system housekeeping and monitoring requirements. The highly efficient electrical and thermal design uses proven topology and components and includes integral cooling fans to further support highly reliable operation; the D1U4-W series is an extension of the D1U product family that has a demonstrated field reliability of 6.8 million hours.
     
    Protection features include auto-recovery from both over-current and over-temperature faults. Status information is provided via front panel LEDs, logic signals and an I2C management interface.
     
    Overall dimensions of the D1U4-W Front End power supply are 355.6mm (L) x 101.6mm (W) x 41mm (H) - (14.0in. x 4.0in. x 1.6in.). If required, four units can be packaged together in an optional 19in. power shelf (S1U-4X) to provide up to 4.8kW of power. All models are fully RoHS compliant and are EMC class A rated. Operating temperature range is 0ºC to +50ºC.
