Power Supplies Kick Out Rated Power Times Two For 10-Second Bursts

Where 24-V peak-current demand is needed for a short duration, the 5- and 24-V ZWD family of dual-output power supplies can deliver 200% of the nominal current rating for up to 10 seconds. These supplies are available with a 5-V, 5-A output for powering logic and auxiliary power circuits, as well as a 24-V output that can deliver a peak current of up to 18 A. Cooled at 50°C, the ZWD100PAF offers continuous 100-W convection and 196-W peak, the ZWD150PAF yields 150-W convection and 294 W peak, and the ZWD225PAF delivers 225-W convection with a peak of 440 W. All three accept input voltages from 85 to 265 V ac and contain active power-factor-correction (PFC) circuitry to meet EN61000-3-2 standards. They also meet EN61000-4-X immunity and Class B electromagnetic interference standards. In addition, they're safety-approved to UL60950, CSA60950, EN60950, and EN50178 specifications, plus they're CE-marked. Prices start at $94 in single-unit quantities.
