DC/DC Converter THM 3WI Series, 3 Watt Ultra wide 4:1 input voltage 3 W DC/DC converter in a compact DIP-24 plastic case I/O isolation 5000 VACrms rated for 250 VACrms working voltage Certification according to IEC/EN/ES 60601-1 3rd edition for 2xMOPP Risk management process according to CB ISO 14971 including risk management file Scheme IEC 606010-1 ES 60601-1 Acceptance criteria for electronic assemblies according to IPC-A-610 Level 3 The THM-3WI series is a range of medical 3 Watt DC/DC converters in DIP-24 plastic package and with ultra-wide 4:1 input voltage range. They provide a rein- Low leakage current < 2A forced isolation system for 5000 VACrms isolation and a very low leakage current Extended operating temperature range of less than 2 A. The units are approved to IEC/EN/ES 60601-1 3rd edition for 40C to 90C. 2 x MOPP (Means Of Patient Protection) and come along with an ISO 14971 risk EMC compliance to IEC 60601-1-2 4th management file. Design and production conform to the quality management edition and EN55032 class A system ISO 13485. With a high efficiency of up to 87% and highest grade com - ponents the converters can reliably operate in an ambient temperature range Operating up to 5000m altitude of 40C up to +90C. They constitute a reliable solution not only for medical 5 year product warranty equipment but also for demanding ranges of application such as transportation, control & measurement or IGBT drivers.
