The Schneider Electric ABLS1A24050E is a single-phase, DIN-rail mounted regulated switch-mode power supply from the Easy Modicon ABL2 range, delivering 24 V DC at up to 5 A (120 W) from a 100-240 V AC input. It is designed for general industrial loads such as small to mid-size PLCs, HMIs, sensors and I/O modules, with an output adjustment potentiometer for cable-drop compensation.
The ABLS1A24050E matches the standard ABLS1A24050's 5 A / 120 W, 24 V DC output in the lighter Easy Modicon ABL2 enclosure, sized for the same PLC-plus-HMI-plus-I/O load where panel depth or cost is the deciding factor. The 21.6-27.6 V output window and 1.1-1.3x In overload threshold keep it within standard 24 V DC equipment tolerance. Four output terminals and a 100,000 h MTBF at 40 degC suit continuous panel duty with straightforward field wiring, and the 20 A / 35 A inrush current at 115 V / 230 V AC should be sized into the upstream branch circuit selection.
