ES 60601-1
• Risk management process according to
ISO 14971 including risk management file
The THM-3 series is a range of medical 3 Watt DC/DC converters in DIP-24
plastic package and with wide 2:1 input voltage range. They provide a reinforced
isolation system for 5000 VACrms 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 ISO 14971 risk
management file. Design and production conform to the quality management
system ISO 13485. With a high efficiency of up to 87.5% and highest grade com-
ponents the converters can reliably operate in an ambient temperature range
of –40°C up to +90°C. 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.
• Acceptance criteria for electronic
assemblies according to IPC-A-610 Level 3
• Low leakage current < 2µA
• Eꢀtended operating temperature range
–40°C to 90°C.
• EMC compliance to IEC 60601-1-2 4th
edition and EN55032 class A
• Operating up to 5000m altitude
• 5 year product warranty
