TDN 3WI DC/DC Converters

TRACO Power TDN 3WI Series DC/DC Converters offer 3W output power in a 13.2mm x 9.1mm x 10.2mm SMD package with a wide 4:1 voltage range. These fully regulated, high-performance converters feature a 1600V_DC I/O isolation voltage, external on/off, and short-current protection. TRACO Power TDN 3WI Series DC/DC Converters meet UL 62368-1 (UL 60950-1) standards. The series is ideal for a wide range of applications where space is limited.
