In a 1U by 2U profile measuring 1.57" x 3.07" x 12.03", the DS series distributed-power systems exhibit a power density in excess of 10 W/in3 and are available with power ratings of 450W and 550W. Accepting input voltages from 90 to 264 Vac, the supplies deliver a 12 Vdc main output and a 3.3 Vdc/3A standby output. Output current at 12 Vdc is up to 45A on the 550W model. Other shared features include current-sharing capabilities, internal OR-ing diodes, over-voltage and over-current protection, active inrush current limiting circuitry, and a typical active power factor correction of less than 0.98 that meets EN61000-3-2 standards for input current harmonic content. Models available later this year will include 650W and 850W units. Depending on the model, prices start at $180 each in OEM quantity. ASTEC POWER, Carlsbad, CA. (760) 930-4600.
