TRACO Power THM-6WI 6W DC/DC Converters

TRACO Power THM-6WI 6W DC/DC Converters are medical 6W DC/DC devices in a DIP-24 plastic package with an ultra-wide 4:1 input voltage range. These converters provide a reinforced isolation system for 5000VAC/RMS isolation and a very low leakage current of less than 2µA. The units are approved to IEC/EN/ES 60601-1 3rd edition for 2xMOPP and come with an ISO 14971 risk management file. The THM-6WI components offer up to 87% efficiency and high-grade components, and can reliably operate in an ambient temperature range of -40°C to +90°C. The TRACO Power THM-6WI 6W DC/DC converters are suitable for medical equipment and demanding applications such as transportation, control/measurement, or IGBT drivers.
