THR High Isolation DC/DC Converters

TRACO Power THR High Isolation DC/DC Converters offer a 3000V_AC reinforced I/O isolation system, a wide 4:1 input voltage range, and an efficiency rating of up to 90%. The THR series is comprised of four power levels covering 3W, 10W, 20W, and 40W and has overload, overvoltage, and short-circuit protections with the latest IEC/EN/UL 62368-1 safety certifications. The 3W, 10W, and 20W models have an internal input filter to meet with EN 55032 Class A. These converters come in either a DIP-24 or 2" x 1" package and feature increased resistance against vibration and shock according to EN 61373. TRACO Power THR DC/DC Converters have an extended operating temperature range of -40°C to +90°C ambient, making them ideal for demanding applications in the industrial, transportation, and instrumentation sectors.
