100- To 150-W External Power Supplies Meet Energy-Efficiency Standards

A new range of AC-DC external power supplies with models rated from 100 to 150 W meet the latest Energy Star, EISA, and CEC standards. The DT100-C and DT150-C series feature active power-factor correction (meets EN61000-3-2) and operate from a universal AC input of 90 to 264 Vac (47-63 Hz). Available output voltages are: 12 V, 16 V, 19 V, 24 V, 36 V, and 48 V. These external power supplies are packaged in an insulated compact and lightweight enclosure measuring 3.35-in. wide by 6.7-in. long by 1.73-in. high, and are convection cooled. The operating temperature range is 0 to +40°C with no derating required. All models are fully isolated (3 kVac input to output) and meet the Energy Star 1.1 and the California Energy Commission (CEC) level IV efficiency standards. Plus, models with outputs of 24 V to 48 V meet the Energy Star 2.0 version level V standards. These units include overvoltage and short-circuit protections, and off/no-load standby power consumption of less than 0.50 W as required by the green energy initiatives. Moreover, these external power supplies feature a recessed IEC320-C14 AC input receptacle and a 3.4-foot output cable with a molded four-pin connector. The DT100-C and DT150-C series are available now and priced from $40.50 each in 1000-unit quantities. TDK-LAMBDA, San Diego, CA. (800) 526-2324.
