Primary-switched STEP POWER power supply for DIN rail mounting, input: 1-phase, output: 12 V DC/1.5 A ## Product Description STEP POWER power supplies for distribution boards 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. ## Your advantages - 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 May 30, 2022, 6:07 AM Page 1 (14) ## Power supply unit - STEP-PS/ 1AC/12DC/1.5/FL ## 2868554 https://www.phoenixcontact.com/us/products/2868554 ## Commercial Data |Commercial Data|| |---|---| |Item number|2868554| |Packing unit|1 pc| |Minimum order quantity|1 pc| |Sales Key|C14| |Product Key|CMPS12| |Catalog Page|Page 284 (C-4-2019)| |GTIN|4046356501521| |Weight per Piece (including packing)|158.1 g| |Weight per Piece (excluding packing)|70 g| |Customs tariff number|85044030| |Country of origin|VN| May 30, 2022, 6:07 AM Page 2 (14) ## Power supply unit - STEP-PS/ 1AC/12DC/1.5/FL 2868554 https://www.phoenixcontact.com/us/products/2868554 ## Technical Data ## Input data AC operation Nominal input voltage range 100 V AC ... 240 V AC Input voltage range 85 V AC ... 264 V AC 95 V DC ... 250 V DC Input voltage range AC 85 V AC ... 264 V AC Input voltage range DC 95 V DC ... 250 V DC Voltage type of supply voltage AC/DC Inrush current < 15 A (typical) Inrush current integral (I[2] t) < 0.1 A[2] s AC frequency range 45 Hz ... 65 Hz Frequency range DC 0 Hz Mains buffering time typ. 15 ms (120 V AC) typ. 70 ms (230 V AC) Current consumption 0.33 A (120 V AC) 0.18 A (230 V AC) Nominal power consumption 37.9 VA Protective circuit Transient surge protection;
