The Schneider Electric ABLS1A12100E is a single-phase, DIN-rail mounted regulated switch-mode power supply from the Easy Modicon ABL2 range, delivering 12 V DC at up to 10 A (120 W) from a 100-240 V AC input. It targets general industrial loads such as small PLCs, HMIs, I/O modules and sensors, with an output adjustment potentiometer to offset voltage drop on long cable runs.
The Easy Modicon ABL2 line trades the aluminum book housing of the standard ABLS1A range for a lighter, cost-efficient enclosure while keeping the same 12 V / 10 A / 120 W output, making the ABLS1A12100E a straightforward fit where panel space and budget both matter. Its 10.8-13.8 V output adjustment range and 1.1-1.3x In overload threshold suit small PLC, HMI and sensor loads rather than motor-heavy circuits. Four output terminals and a vertical mounting position keep wiring straightforward on a shallow DIN-rail panel.
