Medical DC/DC converters

Jon Lawson

The new THM 15WI, THM 20WI and THM 30WI series extend the range of Traco Power high isolated DC/DC converters for medical applications up to 30 Watt.

The DC/DC converters provide a reinforced insulation system for 5000 VACrms with compliance to latest safety standard IEC/EN/ES 60601-1 3rd edition for 2 x MOPP and they are approved for an operating altitude of up to 5000m.

The converters come along with the risk management file according ISO 14971.

Design and production conform to the quality management system ISO 13485 and the converters operate within the EMC emission and immunity levels according to latest standard IEC 60601-1-2 4th edition.

With a high efficiency of up to 90% and highest grade components the converters reliably operate in an ambient temperature range of –40°C up to +85°C while the design size is very small.

A low leakage current of less than 2.5 µA qualifies them for BF (body floating) applications. The new models have a wide 4:1 input voltage range and are available as single or dual output version.

The THM Series models are a reliable solution not only for medical equipment but also for demanding field of application such as transportation, control & measurement or IGBT drivers.
