Series STEP3-PS

STEP3-PS/1AC/12DC/2.5/PT - Power supply unit

Primary-switched power supply unit, STEP POWER, Push-in connection, DIN rail or direct mounting, input: 1-phase, output: 12 V DC / 2.5 A

  • Energy savings with the highest level of efficiency in no-load and part-load operation (Efficiency Level VI)
  • Space savings in the control cabinet due to the narrow design combined with increased performance (up to 100%)
  • Approval for household purposes (EN 60335) allows use in domestic applications
  • Quick and easy startup with tool-free Push-in connection technology at a 45° angle with double terminal points
  • Flexible mounting: Snap onto a DIN rail or screw onto a level surface
