DC/DC Converter TRN 3SM Series, 3 Watt

  • Compact SMD package 11,9 x 11,3 x 8,0 mm
  • Fully regulated outputs
  • Input Voltage range
  • I/O-isolation 1‘600 VDC
  • Operating temperature range –40°C to +85°C
  • Short circuit protection
  • Designed to meet UL 62368-1 (UL 60950-1)
  • 3-year product warranty The TRN 3SM Series comprises 3 Watt fully regulated, high performance DC/DC converters. They come in a compact cubical package of only 1.07 cm³. Full load operation is reliable up tp 65°C environment temperature. With 1’600 VDC I/O-isolation voltage, and short current protection they cover a wide range of application when space is limited. The input of the converters is designed for a wide voltage range (2:1) and minimum load is not required. The functional I/O-isolation system is designed to meet IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC.
