DC/DC Medical Converter THM 20 Series, 20 Watt Wide 2:1 input voltage 20 W DC/DC converter in a 1.6 x 1 plastic case I/O isolation 5000 VAC rated for 250 VAC working voltage Certification according to IEC/EN/ES ES 60601-1 IEC 60601-1 60601-1 3rd edition for 2 x MOPP UL 62368-1 IEC 62368-1 Risk management process according to The THM 20 series is a range of medical 20 Watt DC/DC converters in 1.6 x ISO 14971 incl. risk management file 1.0 plastic package and with wide 2:1 input voltage range. They provide a re- Acceptance criteria for electronic inforced isolation system for 5000 VAC isolation and a very low leakage current assemblies acc. to IPC-A-610 Level 3 of less than 2.5 A. The units are approved to IEC/EN/ES 60601-1 3rd edition for 2 x MOPP and come along with an ISO 14971 risk management file. Design Low leakage current <2.5 A and production conform to the quality management system ISO 13485. With a high efficiency of up to 89% and highest grade components the converters can Operating temperature 40C to 80C reliably operate in an ambient temperature range of 40C up to +80C. They EMC compliance to IEC 60601-1-2 4th constitute a reliable solution not only for medical equipment but also for de- edition and EN55032 class A manding ranges of application such as transportation, control & measurement or IGBT drivers.
