The 2868635 is a 24V/18W 1-output primary switched STEP Power Supply for DIN-rail mounting, 1-phase input for installation distributors. The STEP 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. Reliable power supply high MTBF (mean time between failures) of more than 500000 hours and U/I characteristic curve. Flexible mounting by simply snapping onto the DIN-rail or screwing onto a level surface, energy savings maximum energy efficiency and incredibly low idling losses.
