TDK CORP. TDK-Lambda DTM series of medical and industrial ac-dc external power supplies includes 70W and 160W models. Both power levels are offered with a choice of a Class I IEC320/C14 inlet (with an earth ground connection) or a Class II IEC320/C8 inlet (double insulated, no ground). The Class I models are suitable for medical, industrial, test and measurement and in addition, the Class II (C8 suffix) for medical home healthcare, hospital, clinical and dental applications.

DTM70 and DTM160 series accepts an 80 to 264Vac input, has a no-load power consumption of less than 150mW and efficiencies of up to 93%. This allows the external power supplies to conform to the DoE Level VI Efficiency and the EU Regulation 2019/1782 Eco-design requirements for energy savings.

DTM70 is available with 12V, 15V, 18V, 24V, 36V and 48V output voltages and the DTM160 with 12V, 24V, 36V and 48V. A standard locking DIN output connector prevents accidental disconnection of the output voltage from the host equipment. Other connector versions and cable assemblies are available on request.

The adapters are housed in a robust plastic case with dimensions of only 120 x 52 x 31mm (L x W x H) for the DTM70, and 150 x 70 x 38mm for the DTM160. The Ingress Protection rating is IP21.
