External power supplies meet EISA efficiency standards

TDK-Lambda announces a new range of ac-dc external power supplies with models rated from 100 to 150 watts that meet the EISA, CEC, and Energy Star EPS Version 2.0, Efficiency Level V 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 264 Vac. Available output voltages include 12, 16, 19, 24, 36, and 48 V.

These external power supplies are packaged in an insulated compact and lightweight enclosure measuring 3.35 x 6.7 x 1.73 in. 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 (3k Vac, input to output) and meet the Energy Star 2.0 and the California Energy Commission (CEC) Level V efficiency standards.

These units include overvoltage and short-circuit protections and off/no-load standby power consumption of less than 0.50 watt as required by Energy Star 2.0 and other 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 ft output cable with a molded 4-pin connector. Other output connector types may be special ordered. These 100-150 W supplies are suitable for powering desktop devices, instrumentation, industrial devices, and a wide range of other general purpose applications.
