TDK-Lambda Level VI efficiency-compliant power supplies

The DT100D and DT150D adapter power supplies now comply with Level VI efficiency standards. Suitable for test and measurement, communications and industrial applications, the adapters meet the average-efficiency and no-load power regulations mandated by the DOE. Accepting a 90- to 264-Vac input, the 100- to 150-W adapters are available with 12- to 48-V outputs and can operate in ambient temperatures up to 60 °C (de-rating applies above 40 °C). The products also meet EU Tier 2 requirements. The series is housed in a vent-free enclosure; ac is applied using a standard IEC 60320-C13 cable and dc provided through a four-pin power-DIN connector.
