DC/DC Railway Converter TEQ 300WIR Series, 300 Watt

  • High power block with excellent thermal convection
  • Operating temperature -40°C to +80°C
  • Increased shock & vibration resistance
  • Ultra wide 4:1 input voltage range
  • EN 50155 approval for railway

applications

  • Excellent efficiency up to 92%
  • Constant current output characteristic for battery load applications
  • Power sharing (up to 3 pcs in parallel)
  • Input filter meet EN 55022, class A
  • Under voltage lock-out circuit IEC 62368-1UL 62368-1UL 508 The TEQ 300WIR Series is a family of isolated high performance DC/DC con- verter modules with ultra-wide 4:1 input voltage ranges which come in a rugged, sealed 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 overall heatsink construction allows an operating tem- perature up to +55°C with natural convection cooling without power derating and up to +80°C with power derating. Further features include output voltage trimming, Remote On/Off and under voltage lockout. The ultra wide input volt- age range makes these converters also an interesting solution for battery oper- ated systems.
