ISO 14971 including risk management file
Acceptance criteria for electronic
CB
assemblies according to IPC-A-610 Level 3
Scheme
IEC 60601-1
ES 60601-1
Low leakage current < 2.5 µA
The THM-20 series is a range of medical 20 Watt DC/DC converters in 1.6” x 1.0”
Extended operating temperature range
–40°C to 80°C.
EMC compliance to IEC 60601-1-2 4th
edition and EN55032 class A
Operating up to 5000m altitude
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 2.5 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 89% and highest grade com-
5 year product warranty
ponents the converters can reliably operate in an ambient temperature range
of –40°C up to +80°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.
