Intrinsically Safe PSU

 

Features

  • Available with either Ex (ia) or Ex me (ia) protection
  • Available with a range of outputs from 12V to 24V.
  • Available with either 110V (max 115V) or 240V (max 250V) AC input
  • Inrush current protection
  • Fully encapsulated 
  • IS outputs are floating
    (i.e. they are galvanically isolated from the mains input, the mains earth and the PSU enclosure).
  • The power supplies have a 12 month, return to factory, replacement warranty
  • Status indicator LED and Buttons;
    • IS Power On LED (all PSUs have this fitted)
    • Temp/Current Limit LED (if fitted)
      The temp/current LED is illuminated when one of the three current limit stages shuts down due to an overload.
    • Voltage Regulator Failure LED (if fitted)
      This LED indicates the first Voltage regulator stage has failed
    • 3 current limit test buttons (if fitted).
      Allows the user to test the integrity of each of the 3 current limit stage
