The THM-3WI series is a range of medical 3 Watt DC/DC converters in DIP-24 plastic package and with ultra-wide 4:1 input voltage range. They have reinforced isolation system for 5000 VACrms 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% and highest grade components, 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 more complex applications such as transportation, control & measurement or IGBT drivers. MTBF according MIL-HDBK-217F at +25°C, reach more than 2.000.000h, which is an excellent value.
