Capable of peak-power levels up to 600W, the SDR250 series ac/dc power supplies offer single and dual outputs and the U-channel version measuring 81.2 mm x 127 mm x 38.1 mm specifies a power density of 10.4W per cubic inch while requiring 16 CFM of forced air cooling to achieve a 250W output. Other mechanical formats include a U channel with vented cover and an enclosed, fan-cooled model. Employing convection cooling alone the single output versions deliver up to 135W. The series offers 11 single and six dual-output models. Output voltages for the single output versions range from 5 to 60 Vdc. Dual output units provide combinations of 3.3, 5, 12, 24, and 48 VDC. Pricing for OEM quantities of the single output U bracket models is $117 each. For further information, contact Duane Darrow at XP POWER, Sunnyvale, CA. (408) 732-7777.
