DC/DC Converters THM 3WI Series, 3 Watt Features Ultra wide 4:1 input voltage I/O isolation 5000 VACrms rated for ES 60601-1 250 VACrms working voltage 2 x MOPP Medical safety according to AAMI/ANSI ES 60601-1:2005(R) and IEC/EN 60601-1 3rd edition Low leakage current <2 A Very high efficiency up to 87% Extended operating temperature range -40C to 94C at full load. Input filter to meet EN55022 class A 3-year product warranty 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 complies 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 demanding applications such as transportation systems, industrial control equipments, measurement equipments, and some IGBT driver applications. With A high efficiency of up to 87% and highest grade components the converters can reliably operate in an ambient temperature range of -40 up to +94C at full load.
