DC/DC Medical 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 VAC rated for 250 VAC working voltage Certification according to IEC/EN/ES 60601-1 3rd edition for 2 x MOPP ES 60601-1 IEC 60601-1 UL 62368-1 IEC 62368-1 Risk management process according to ISO 14971 incl. risk management file 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 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 A. The units are approved to IEC/EN/ES 60601-1 3rd edition Low leakage current <2 A 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 Operating temperature 40C to 90C high efficiency of up to 87% and highest grade components the converters can EMC compliance to IEC 60601-1-2 4th reliably operate in an ambient temperature range of 40C up to +90C. They edition and EN55032 class A constitute a reliable solution not only for medical equipment but also for de- manding ranges of application such as transportation, control & measurement Operating up to 5000m altitude or IGBT drivers. 5-year product warranty Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
