DC/DC Converter THM 15 Series, 15 Watt
The THM 15 series is a range of medical 15 Watt DC/DC converters in 1.6” x 1.0”
plastic package and with wide 2:1 input voltage range. They provide a reinforced
isolation system for 5000 VACrms isolation and a very low leakage current of
less than 2.5 A. The units are approved to IEC/EN/ES 60601-1 3rd edition for
2  MOPP (Means Of Patient Protection) and come along with an ISO 14971 risk
management file. Design and production conform to the quality management
system ISO 13485. With a high efficiency of up to 90% and highest grade com-
ponents the converters can reliably operate in an ambient temperature range
of –40°C up to +85°C. They constitute a reliable solution not only for medical
equipment but also for demanding ranges of application such as transportation,
control & measurement or IGBT drivers.
