THR-WI Series DC/DC Converters
TRACO Power's converters with double/reinforced insulation provide up to 3,000 VAC isolation
TRACO Power's THR-WI series of 3 W, 10 W, 20 W, and 40 W DC/DC converters with double/reinforced insulation provide up to 3,000 VAC isolation. These products operate over an ultra-wide 4:1 input range with up to 90% efficiencies and operating temperatures from -40°C to +80°C (+105°C maximum case temperature).
THR 3 (3 W) models offer DIP 24 footprints, and the THR 10, THR 20, and THR 40 (10 W, 20 W, and 40 W) come in 2" x 1" footprints. Input ranges include 9 VDC ~ 36 VDC, 18 VDC to 75 VDC, and 40 VDC ~ 160 VDC and provide single and dual outputs ranging from 5 VDC to approximately 24 VDC. Models are fully encapsulated to withstand shock and vibration standards per IEC/EN 61373. Internal input filters enable EN 55032 class A compliance (3 W, 10 W, and 20 W) and overload, overvoltage, and short-circuit protection. With the latest IT safety certifications (IEC/EN/UL 62368-1), the THR-WI series is the perfect choice for many demanding applications in the industrial, transportation, and instrumentation sectors.
