STEP-PS/ 1AC/12DC/1.5/FL - Power supply unit

Primary-switched STEP POWER power supply for DIN rail mounting, input: 1-phase, output: 12 V DC/1.5 A

  • Flexible mounting by simply snapping onto the DIN rail or screwing onto a level surface
  • Reliable power supply thanks to high MTBF (mean time between failures) of more than 500,000 hours and U/I characteristic curve
  • Energy savings thanks to maximum energy efficiency and incredibly low idling losses
