DC/DC Converter THR 20WI Series, 20 Watt Reinforced I/O-isolation 3000 VAC Shock and vibration resistance according to EN 61373 Wide 4:1 input voltage range: 9-36, 18-75, 40-160 VDC Operating temperature range -40 to +85C UL 62368-1 IEC 62368-1 Internal EN 55032 class A filter The THR 20WI is 20 Watt DC/DC converters series with reinforced isolation (3000 VAC). These regulated DC/DC converters come in either a 2 x1 pack- High efficiency up to 88% age and also feature increased resistance against shock and vibration accord- ing to EN 61373. The THR 20WI offers an internal input filter to comply with Protection against overload, overvoltage EN 55032 class A. High efficiencies up to 88% allow safe operation from and short circuit 40C to +80C (with derating). All models have a wide 4:1 input voltage 3-year product warranty range and precisely regulated, isolated output voltages. With the latest IT safety certifications (IEC/EN/UL 62368-1) the THR 20WI series is the perfect choice for many demanding applications in the industrial, transportation and instru- mentation sectors.
