Top-Hat Rail Power Supplies

Our Industrial Solutions are mounted on a top-hat rail in a control cabinet. Thanks to the selectable power supply of the USB Deviceserver INU-100 and the USB Hub IH-304, you can flexibly connect these devices. You either use your existing power supply or—if there is none or no vacancy—you can buy a new one. In this case you can save the cumbersome and time-consuming search—simply use the top-hat rail power supplies DRP-20 and DRP-75. We selected them specifically to perfectly match our industrial solutions!

  • Universal input
  • Installation on top-hat rail (according to DIN EN 60715; 35 mm wide / 7.5 or 15 mm deep)
