TDN 1WI DC/DC Converters

TRACO Power TDN 1WI DC/DC Converters feature 1W output power and a wide 4:1 voltage range in a 13.2mm x 9.1mm x 10.2mm DIP package. The fully regulated converters offer 1600V_DC I/O isolation voltage, short-current protection, and external on/off. TRACO Power TDN 1WI DC/DC Converters meet UL 62368-1 (UL 60950-1) regulations. These high-performance units are designed for a wide range of applications where space is limited.
