Compact external AC/DC power adapters for medical and industrial applications

TDK Corporation has added the TDK-Lambda brand DTM70 and DTM160 series to the DTM family of compact medical and industrial AC/DC power adapters. They are available in multiple power classes from 36W to 300W. These series are provided in Class I versions with a protective earth terminal on the input and Class II versions with double insulation protection. The adapters are provided in a robust plastic case with dimensions of just 120mm x 52mm x 31mm (DTM70) and 150mm x 70mm x 38mm (DTM160). The DTM70 is offered with 12V, 15V, 18V, 24V, 36V and 48V output voltages and the DTM160 with 12V, 24V, 36V and 48V.

Both series are ideal for 2MOPP medical applications and general industrial use. Both adapter series are certified to the IEC/EN/UL 60601-1 medical safety standard for clinical applications. Also, IEC 60601-1-11 certification is offered for all Class II versions, enabling these adapters to be employed in home healthcare applications. For all versions, EMC is tested according to IEC 60601-1-2 Ed 4, which simplifies usage with medical equipment. For industrial and ICT applications, all models are tested according to IEC/BS/EN 62368-1 and are certified for installation altitudes up to 5000m.

One special feature is the standard locking DIN output connector, which stops unintentional disconnection of the adapter's output voltage. Other connector versions and cable assemblies are provided on request.

Due to the high efficiencies and the low no-load power consumption of lower than 150mW, the adapters comply with EU Regulation 2019/1782 (Eco-design requirements for external power supplies) and the US DOE Level VI specification. CE and UKCA markings confirm compliance with the low voltage, EMC and RoHS directives.
