THM-3WI 3W DC/DC Converters

TRACO Power THM-3WI 3W DC/DC Converters are medical 3W DC/DC converters in a DIP-24 plastic package with an ultra-wide 4:1 input voltage range. These converters provide a reinforced isolation system for 5000V_AC/RMS isolation and a very low leakage current of less than 2µA. These units are approved to IEC/EN/ES 60601-1 3rd edition for 2xMOPP and come with an ISO 14971 risk management file. With an efficiency of up to 87% and high-grade components, the converters can reliably operate in an ambient temperature range of -40°C up to +90°C. The TRACO Power THM-3WI devices offer a reliable solution for medical equipment as well as demanding ranges of applications such as transportation, control/measurement, or IGBT drivers.
