DC/DC Railway Converter TEQ 20WIR Series, 20 Watt

  • High power block with excellent thermal convection
  • Operating temperature -40°C to +93°C
  • Ultra wide 4:1 input voltage range
  • EN 50155 approval for railway

applications

  • Excellent efficiency up to 88%
  • Input filter meet EN 55022 class B
  • I/O isolation up to 1591 VAC
  • Under voltage lock-out circuit
  • Protection against overvoltage, overtemperature and short circuit
  • Output LED indicator IEC 62368-1UL 62368-1 The TEQ 20WIR Series is a family of isolated high performance DC/DC convert- er modules with ultra-wide 4:1 input voltage ranges which come in a rugged metal case. These converters are suitable for a wide range of applications, but the product is designed particularly also for industrial applications where often no PCB mounting is possible but the module has to be mounted on a chassis. A very high efficiency and the heatsink construction allows an operating tem- perature up to +83°C with natural convection cooling without power derating and up to +93°C with power derating. Further features include under voltage lockout, over temperature protection and short circuit protection. Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
