STEP3-PS/1AC/24DC/4/PT Power supply unit Data sheet 109400 en 01 PHOENIX CONTACT 2021-04-26 1 Description The STEPPOWER power supplies with Push-in connection technology are the professional solution for intelligent Technical data (short form) building automation. The compact devices are economical, Input voltage range 100 VAC ... 240 VAC -15% ... +10% space-saving, and flexible in application. 110 VDC ... 250 VDC -10%...+40% Mains buffering typ. 20 ms (120VAC) typ. 20 ms (230VAC) Features Nominal output voltage (U ) 24 VDC N Device design for use in surface-mounted or flush- Setting range of the output voltage 22 VDC ... 27 VDC mounted distributors (VDE0603-1, DIN43871) (U ) Set Energy savings with the highest level of efficiency in no- Nominal output current (I ) 4 A N load and part-load operation (Efficiency Level VI) Output power (P ) 96 W N Space savings in the control cabinet due to the narrow Efficiency Level VI design combined with increased performance (up Efficiency (for nominal values) > 93 % (120VAC) to100%) > 94 % (230VAC) Can be used throughout the world, thanks to the wide Residual ripple typ. 150 mV PP range input and comprehensive international approval MTBF (IEC 61709, SN 29500) > 1350000 h (25C) > 750000 h (40C) package > 488000 h (50C) Approval for household purposes (DINEN60335-1) Ambient temperature (operation) -10 C ... 70 C (Derating: >50C 2%/K) allows use in domestic applications Startup type tested -25 C Quick
