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 * 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 reAcceptance criteria for electronic inforced isolation system for 5000 VAC isolation and a very low leakage current assemblies acc. to IPC-A-610 Level 3 * * * * Low leakage current <2 A * * Operating up to 5000m altitude Operating temperature -40C to 90C EMC compliance to IEC 60601-1-2 4th edition and EN55032 class A ES 60601-1 IEC 60601-1 of less than 2 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 and production conform to the quality management system ISO 13485. With a high efficiency of up to 87% and highest grade components the converters can reliably operate in an ambient temperature range of -40C up to +90C. They constitute a reliable solution not only for medical equipment but also for demanding ranges of application such as transportation, control & measurement or IGBT drivers. 5-year product warranty Models Order Code Input Voltage Range THM 3-0510WI THM 3-0511WI THM 3-0512WI THM 3-0513WI THM 3-0515WI THM 3-0521WI THM 3-0522WI THM 3-0523WI THM 3-2410WI THM 3-2411WI THM 3-2412WI THM 3-2413WI THM 3-2415WI THM 3-2421WI THM 3-2422WI THM 3-2423WI THM 3-4810WI THM 3-4811WI THM 3-4812WI THM 3-4813WI THM 3-4815WI THM 3-4821WI THM 3-4822WI THM 3-4823WI www.tracopower.com 4.5 - 9 VDC (5 VDC nom.) 9 - 36 VDC (24 VDC nom.) 18 - 75 VDC (48 VDC nom.)
