DC/DC Converter THR 40WI Series, 40 Watt Reinforced I/O-isolation 3000 VAC Shock and vibration resistance according to EN 61373 Wide 4:1 input voltage range: 36-160 VDC Operating temperature range -40 to +80C UL 62368-1 IEC 62368-1 High efficiency up to 90% The THR 40WI is 40 Watt DC/DC converters series with reinforced isolation (3000 VAC). These regulated DC/DC converters come in either a 2 x1 pack- Protection against overload, overvoltage age and also feature increased resistance against shock and vibration accord- and short circuit ing to EN 61373. High efficiencies up to 90% allow safe operation from 40C to +70C (with derating). All models have a wide 4:1 input voltage range and 3-year product warranty precisely regulated, isolated output voltages. With the latest IT safety certifica- tions (IEC/EN/UL 62368-1) the THR 40WI series is the perfect choice for many demanding applications in the industrial, transportation and instrumentation sectors.
