The Schneider Electric ABLS1A24031 is a Modicon Optimized regulated switch-mode power supply that converts a 100-240 V AC single-phase (or 140-340 V DC) input into a stable 24 V DC output at 3.13 A, delivering 75 W. It mounts on a 35 mm DIN rail and protects connected loads against overload, short-circuit, and overvoltage with automatic or manual reset.
Choose the ABLS1A24031 where only single-phase AC or DC field supply is available and the connected load draws up to 3.13 A - at 27 mm wide, it is among the narrowest footprints in the Modicon ABL power supply line, useful where DIN-rail space is tight. Applications needing a three-phase 380-500 V AC input or higher output current call for the wider Universal-range units in the same family.
