DC/DC Medical Converter THM 15WI Series, 15 Watt Ultra wide 4:1 input voltage 15 W DC/DC converter in a 1.6 x 1 plastic case I/O isolation 5000 VAC rated for 250 VAC working voltage ES 60601-1 IEC 60601-1 Certification according to IEC/EN/ES UL 62368-1 IEC 62368-1 60601-1 3rd edition for 2 x MOPP The THM 15WI series is a range of medical 15 Watt DC/DC converters in 1.6 x Risk management process according to 1.0 plastic package and with wide 4:1 input voltage range. They provide a re- ISO 14971 incl. risk management file inforced isolation system for 5000 VAC isolation and a very low leakage current Acceptance criteria for electronic of less than 2.5 A. The units are approved to IEC/EN/ES 60601-1 3rd edition assemblies acc. to IPC-A-610 Level 3 for 2 x MOPP and come along with an ISO 14971 risk management file. Design and production conform to the quality management system ISO 13485. With a Low leakage current <2.5 A high efficiency of up to 90% and highest grade components the converters can reliably operate in an ambient temperature range of 40C up to +85C. They Operating temperature 40C to 85C constitute a reliable solution not only for medical equipment but also for de- EMC compliance to IEC 60601-1-2 4th manding ranges of application such as transportation, control & measurement edition and EN55032 class A or IGBT drivers.
