DC/DC Converter TMDC 20 Series, 20 Watt

  • Fully encapsulated low profile plastic case
  • Ultra wide 4:1 input voltage range
  • Operating temperature range –40°C to +90°C
  • I/O isolation 2500 VDC
  • Excellent efficiency up to 91 %
  • Input filter to meet EN 55022, class A
  • Optional DIN-Rail mount adapter
  • No minimum load required
  • Power good LED indicator and remote on/off function
  • 3-year product warranty IEC 62368-1UL 62368-1 The TMDC 20 Series is a range of encapsulated high performance DC/DC con- verter modules. With a very high efficiency of up to 91% and the use of highest grade components these 20 W converters are made for a reliable operation in the temperature range of -40°C up to 90°C. They come in chassis mount ver- sion with screw terminal block. The 8 models have a wide 4:1 input voltage range and a tight output voltage regulation. They do not need a minimum load and offer a high efficiency also at low load conditions. They feature a remote control input and a green power good LED which indicates the presence of the output voltage. Protection against overload and short circuit are standard fea- tures of these converters. EMC characteristics and safety certifications are aligned for the operation in industrial environment.
