TDK-Lambda Power supplies with Level VI efficiency
These ITE-certified DTM300-D external power supplies offer a choice of Class I or Class II (no ground connection) inputs and meet the Level VI DoE standards for efficiency and off-load power. The convection-cooled power supply is housed in a rugged, vent-free enclosure; ac is applied using the standard IEC 60320-C14 (three-prong) or 60320-C18 (two-prong) connector, and dc is provided through a 10-pin Molex Mini-Fit connector. Other connectors are available. The adapters also feature over-voltage and over-current protection. Accepting a 90- to 264-Vac input, the 300-W adapters are available with 12-, 19-, 24-, 28-, 48- and 54-V outputs and can operate in ambient temperatures ranging from -30 to 60 °C.
