DC/DC Converter
THM 20 Series, 20 Watt
• Wide 2:1 input voltage 20 W DC/DC
converter in a 1.6 x 1 ” plastic case
• I/O isolation 5000 VACrms rated for
250 VACrms working voltage
• Certification according to IEC/EN/ES
60601-1 3rd edition for 2xMOPP
• Risk management process according to
ISO 14971 including risk management file
• Acceptance criteria for electronic
CB
assemblies according to IPC-A-610 Level 3
Scheme
ES 60601-1
IEC 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”
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 ꢀ 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-
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.
• Eꢀtended 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
• 5 year product warranty
