The THM-3WI series is a range of high performance, regulated 3 Watt DC/DC
converters in a DIP-24 plastic package. The reinforced I/O-isolation system com-
plies with the medical safety requirements for MOPP (Means Of Patient Protection).
Together with a wide 4:1 input voltage range, and an internal EMI filter to meet
EN55022 class A the converters constitute also a reliable solution for many de-
manding applications such as transportation systems, industrial control equipments,
measurement equipments, and some IGBT driver applications. With A high efficien-
cy of up to 87% and highest grade components the converters can reliably operate
in an ambient temperature range of –40 up to +94°C at full load.
