THM 10WI Series, 10 Watt
• Ultra wide 4:1 input voltage 10 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 10WI series is a range of medical 10 Watt DC/DC converters in
• Acceptance criteria for electronic
assemblies acc. to IPC-A-610 Level 3
• Low leakage current <2 µA
DIP-24 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 (Means Of Patient Protection) and come along with an
• Operating temperature –40°C to 90°C • EMC compliance to IEC 60601-1-2 4th
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 tem-
edition and EN55032 class A
perature range of –40°C up to +90°C. They constitute a reliable solution not
• Operating up to 5000m altitude • 5-year product warranty
only for medical equipment but also for demanding ranges of application such as transportation, control & measurement or IGBT drivers.
