Primary-switched STEP POWER power supply for DIN rail mounting, input: 1-phase, output: 24 V DC/4.2 A 

## Product Description 

STEP POWER power supplies for installation distributors 

The STEP POWER power supply range was developed especially for building automation. The low idling losses and high degree of efficiency ensure maximum energy efficiency. They allow flexible use and can be snapped onto the DIN rail or screwed onto an even surface. 

## Why buy this product 

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
