TRACO POWER TDN34811WISM DC/DC Converter

The TDN 3WISM Series is a set of compact, high-performance 3 Watt DC/DC converters designed in an SMD package measuring 13.2 x 9.1 x 10.2 mm. They feature fully regulated outputs, 1600 VDC isolation, and operate reliably from -40°C to +70°C without derating. These low-profile converters include short-circuit protection, remote On/Off, and meet IEC/EN 62368-1 standards with a 1,600 VDC isolation voltage. Suitable for space-constrained applications, they ensure stable power conversion with high efficiency, minimal noise, and safety compliance.
