500 WattsFeatures

  • Autoranging 115/230 Vac input
  • Two, low profile, chassis mount versions
  • 500 Watts
  • Me etsEN55022-B
  • Meets EN61000-3-2 harmonic current limits
  • Rugged coldplate construction Product Overview The International Front End (IFE) is an enclosed chassis mount, AC Front End which may be used with VIPAC Arrays, MegaModules or any of Vicor's 300V input DC-DC converters to create a complete, low profile, high density, AC-DC power supply. The IFE operates from worldwide AC mains and includes autoranging line rectification, integral EMI filtering, hold-up capacitors, harmonic current attenuation and transient suppression. The IFE incorporates Vicor's passive harmonic current attenuation technology and FARM modules to deliver 500 Watts while meeting EN61000-3-2 limits. All internal heat producing components are coupled to the chassis for optimal thermal transfer. Two rugged, coldplate packages are available — one with threaded inserts and the other with thru hole flanges — which may be mounted directly to a cabinet wall or an existing heat sink for high temperature operation. The International Front Ends (IFE) provide an off-the-shelf solution for many custom and standard power supply requirements where space constraints and time to market are critical.
