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
• Risk management process according to
ES 60601-1 IEC 60601-1 UL 62368-1 IEC 62368-1
ISO 14971 incl. risk management file The THM 3WI series is a range of medical 3 Watt DC/DC converters in DIP-24
• Acceptance criteria for electronic
assemblies acc. to IPC-A-610 Level 3
• Low leakage current <2 µA
plastic package and with ultra-wide 4:1 input voltage range. They provide a reinforced isolation system for 5000 VAC isolation and a very low leakage current of less than 2 µA. 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
• Operating temperature –40°C to 90°C • EMC compliance to IEC 60601-1-2 4th
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 –40°C up to +90°C. They
