STEP-PS/ 1AC/24DC/0.5 is a primary-switched power supply unit. The STEP POWER power supply for DIN rail mounting 1 phase input. This 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. It is flexible mounting by simply snapping onto the DIN rail or screwing onto a level surface. It has reliable power supply for high MTBF (mean time between failures) of more than 500,000 hours and U/I characteristic curve. Approved by UL/C-UL listed UL 508, UL/C-UL, UL 60950-1, UL ANSI/ISA-12.12.01 class I, division 2, groups A, B, C, D T4 (hazardous location), NEC class 2 as per UL 1310.
