DC/DC Converter TRA 3 Series, 3 Watt

  • Semi-regulated output (load)
  • Highest power density 3W SIP-Converter
  • Industry standard pinout
  • High efficiency up to 89%
  • I/O isolation voltage 1000 VDC
  • Operating temperature range –40°C to +95°C
  • 3-year product warranty IEC 62368-1UL 62368-1 The TRA 3 series are miniature, I/O-isolated 3W DC/DC-converters with a semi load regulation. They are the ideal solution to power drivers and circuits where unregulated DC/DC converters do not meet the input voltage range at load change Models Order Code Input Voltage Output Voltage Output Current Efficiency Range nom. max. typ.
