THN 20WIR Series Ruggedized 20W DC/DC Converters

TRACO Power THN 20WIR Series Ruggedized 20W DC/DC Converters are ruggedized 20W DC/DC converters providing high reliability in harsh environments. THN 20WIR converters have a wide 4:1 input range and increased resistance against electromagnetic interference, shock/vibration, and thermal shock. These TRACO Power devices come in a six-side shielded 1" x 1" metal package. This innovative design provides high efficiencies up to 91%, enabling a convection-cooled, full load operating temperature range from -40°C to +65°C without derating.
