Shock and vibration resistance
according to EN 61373
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
Protection against overload, overvoltage 61373. The THR 3WI offers an internal input filter to comply with EN 55032
class A. High efficiencies up to 85% allow safe operation from –40°C to
and short circuit
+92°C (with derating). All models have a wide 4:1 input voltage range and pre3-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 demanding applications in the industrial, transportation and instrumentation sectors.
