DC/DC Converter THR 3WI Series, 3 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 +92C UL 62368-1 IEC 62368-1 Internal EN 55032 class A filter The THR 3WI is 3 Watt DC/DC converters series with reinforced isolation (3000 VAC). These regulated DC/DC converters come in either a DIP-24 package and High efficiency up to 85% also feature increased resistance against shock and vibration according to EN 61373. The THR 3WI offers an internal input filter to comply with EN 55032 Protection against overload, overvoltage class A. High efficiencies up to 85% allow safe operation from 40C to and short circuit +92C (with derating). All models have a wide 4:1 input voltage range and pre- 3-year product warranty cisely regulated, isolated output voltages. With the latest IT safety certifications (IEC/EN/UL 62368-1) the THR 3WI series is the perfect choice for many de- manding applications in the industrial, transportation and instrumentation sec- tors.
