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, the 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.

STEP POWER power supplies with 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 power supply units are particularly suitable for use in distribution boards.

STEP POWER power supply for mounting on a level surface

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

STEP POWER power supply with 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 for easy potential distribution and loop through.

The 45-degree angle facilitates ergonomic wiring during installation.
