Traco Power has introduced a new THR Line of Reinforced isolated DC/DC converters designed for industrial, transportation, and instrumentation applications. These converters feature increased resistance against shock and vibration according to EN 61373 and come in either a DIP-24 or a 2”x1” package. The THR line comprises four series of DC/DC converters between 3 and 40 Watt with reinforced isolation (3000 VAC) and high efficiencies of these devices allow safe operation from –40°C to +80°C (with derating). All models have a wide 4:1 input voltage range and precisely regulated, isolated output voltages. Moreover, The THR 3WI, THR 10WI, and THR 20WI also have an internal input filter to comply with EN 55032 class A.
