The THR line comprises four series of DC/DC converters between 3W and 40W with reinforced isolation (3,000VAC). These regulated DC/DC converters come in either a DIP-24 or 2”x1” package and also feature increased resistance against shock and vibration according to EN 61373. The THR 3WI, THR 10WI and THR 20WI also have an internal input filter to comply with EN 55032 class A. Efficiencies up to 90% 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. With the latest IT safety certifications (IEC/EN/UL 62368-1) the THR line is the perfect choice for many demanding applications in the industrial, transportation and instrumentation sectors.
