Rail Power Supplies Ruggedized & Certified For Hazardous Locations


Certified to ATEX II3G and UL HazLoc Class I / Div 2 Ruggedized to meet Railway Shock and Vibration (EN61373)

TRACO POWER has announced the release of their TIB 480-EX Family of 480 Watt DIN rail power supplies that are designed for harsh environments & hazardous locations with certifications for ATEX II3G and UL HazLoc Class I / Div 2 standards.

It is packaged in a rugged metal enclosure that is EN61373 qualified for railway shock and vibration. Protection circuits include back power immunity, short-circuit / overload protection and a DC OK dry signal contact. A slim design allows optional side mounting in flat panels with DC-OK LED indicators on both the front and side panels. Reduced heat dissipation enables a wide range operational temperatures. Outputs are radio-interference-suppressed to impede radiation at long output lines reducing common mode current within limits of telecommunication ports. The units operate with a high active power factor correction which also minimizes input inrush current.

Key Features

  • 24 / 48V outputs (-2% ~ +17% VADJ Range)
  • High efficiency of 95%
  • 150% peak power for 4 seconds
  • -40°C to +60°C full load operating temperature range (up to +70°C with only 20% de-rating)
