  • Space savings in the control cabinet due to the narrow design combined with increased performance (up to 100%)
  • Approval for household purposes (EN 60335) enables 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

Approvals for household purposes

STEP POWER power supplies are certified to DIN EN 60335-1  

STEP POWER power supplies are certified to DIN EN 60335-1

Along with the standard industrial approvals, the STEP POWER power supplies have been certified for household purposes in accordance with DIN EN 60335-1 for the first time. They satisfy the most stringent safety requirements for electrical appliances and are the ideal solution for domestic applications.

Safe charging station supply

STEP POWER for e-mobility  

STEP POWER for e-mobility

The STEP POWER power supply will prepare you ideally for e-mobility.

It supplies the charging controller for your charging station safely and reliably. This is because STEP POWER has been developed and tested functionally and in particular with respect to electromagnetic compatibility (EMC) in accordance with the charging station standard EN 61851-21-2. 

Save energy in buildings

STEP POWER power supply in use  

STEP POWER power supplies offer maximum energy efficiency

With low no-load losses (0.1 W or 0.21 W) and a high degree of efficiency, the STEP POWER power supply ensures optimum energy efficiency in buildings. Due to the high degree of efficiency, STEP POWER power supplies convert less electrical energy into undesired heat energy. This not only saves energy, but also extends the service life of all components in the control cabinet.

Optimized performance classes

Optimized performance classes

The STEP POWER power supplies offer an improved performance class for each horizontal pitch. This means more space in the control cabinet combined with increased performance. With their special compact, slim-line design, standardized to DIN 43880, the STEP POWER power supplies are particularly suitable for use in distribution boards.

Flexible mounting

Screwing on without additional mounting material  

Mounting on a level surface

The STEP POWER power supplies offer flexible mounting: they can either be snapped onto a DIN rail or screwed onto a level surface.
The base latches integrated in the housing eliminate the need for additional mounting material when mounting on level surfaces.

Push-in connection technology

STEP POWER with maximum energy efficiency  

Push-in connection technology

The new STEP POWER power supplies enable tool-free Push-in connection technology for the first time. Using the same installation space, the connection terminal block also provides double the number of terminal points so potentials can be easily distributed and looped through.

The 45-degree angle facilitates ergonomic wiring during installation.
