DC/DC Converter THM 60WI Series, 60 Watt Wide 4:1 input voltage 60 W DC/DC converter in a compact 2.3 x 1.45 plastic case I/O isolation 5000 VAC rated for 250 VAC working voltage Certification according to IEC/EN/ES 60601-1 3rd edition for 2 x MOPP Risk management process according to ISO 14971 Acceptance criteria for electronic assemblies acc. to IPC-A-610 Level 3 ES 60601-1 IEC 60601-1 Low leakage current <4.5 A UL 62368-1 IEC 62368-1 Operating temperature range: -40 to The THM 60WI series is a range of medical 60 Watt DC/DC converters in a +75C compact 2.3 x 1.45 plastic package and with wide 4:1 input voltage range. They provide a reinforced isolation system (5000 VAC) and a very low leakage EMC compliance according to IEC current of less than 4.5 A. With a high efficiency of up to 92% and high- 60601-1-2 4th edition est-grade components the converters can reliably operate in an ambient tem- Operating up to 5000m altitude perature range of 40C up to +75C with derating. For more demanding ap- plications regarding temperature, Traco also offers a special heatsink which will 5 year product warranty greatly increase the thermal capabilities for natural convection conditions. The units are approved according to IEC/EN/ES 60601-1 3rd edition for 2 x MOPP as well as IEC/EN/UL 62368-1 and come along with an ISO 14971 risk man- agement file. Design and production conform to the quality management sys- tem ISO 13485. The THM 60WI constitutes a reliable solution not only for med- ical equipment but also for demanding ranges of application such as control & measurement and transportation.
