THN 30WIR Railway & Industrial DC/DC Converters

TRACO Power THN 30WIR Series 30W Railway and Industrial DC/DC Converters are designed to provide high reliability in harsh environments. The series offers an EN 50155-certified wide 4:1 input voltage range (9V_DC to 36V_DC, 18V_DC to 75V_DC, 36V_DC to 160V_DC) with an output power of 30W in a 1" x 1" encapsulated metal package. The six-sided shielded design protects against electromagnetic interference (EMI) while the full encapsulation provides high resistance to thermal shocks, mechanical shocks, and vibration. TRACO Power THN 30WIR Series 30W Railway and Industrial DC/DC Converters offer up to 91% efficiency and operate at an ambient temperature range from -40°C to +65°C without derating and without the need for additional cooling. The THN 30WIR series is EN 61373 certified for mechanical shock and vibration and EN 45545-2 certified for fire behavior. These units come with IEC/EN/UL 62368-1 safety approvals and are designed for high-performance in harsh environments.
