The compact design of the STEP POWER generation power supply units makes them especially suitable for installation distributors and flat control panels. The power supply units are available with DC 24 V output voltage in various performance classes and widths. Their high degree of efficiency and the low idling losses make for high energy efficiency. The power supply unit series is used for power supply of Bender devices.


  • Easy DIN rail and wall mounting
  • Maximum energy efficiency thanks to low idling losses
  • Fast commissioning with LED function monitoring
  • High operational reliability thanks to long power failure buffering under full load and high MTBF (> 500,000 h)
  • Can be used worldwide in all industrial sectors due to a wide-range input and an international approval package
  • Wide temperature range from -25 °C to +70 °C
  • Can be connected in parallel to increase power
