TDK-Lambda 100-150W External Power Supplies Meet New Energy Efficiency Standards

TDK-Lambda has released a new range of ac-dc external power supplies with models rated from 100 to 150W that meet the latest Energy Star, EISA, and CEC standards. The DT100-C and DT150-C series feature active PFC (meets EN61000-3-2) and operate from a universal ac input of 90 to 264Vac (47-63Hz). Available output voltages include 12, 16, 19, 24, 36 and 48V.

These external power supplies are packaged in an insulated compact and lightweight enclosure measuring 3.35" wide by 6.7" long by only 1.73" high and are convection cooled (no fans needed). The operating temperature range is 0 to +40°C with no derating required. All models are fully isolated (3kVac, 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 to 48V 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 0.50W as required by the green energy initiatives. In addition, these series include UL/EN/IEC60950-1 international safety agency certifications and meet EN55022-B and FCC Class B conducted and radiated EMI standards.

Moreover, these external power supplies feature a recessed IEC320-C14 AC input receptacle and a 3.4 foot long output cable with a molded 4-pin connector. Other output connector types can be special ordered. These 100-150W supplies are ideal for powering instrumentation, industrial devices and a wide range of other general purpose applications.

The DT100-C and DT150-C series are available now and priced from $40.50 each in OEM quantities of 1,000 units.
