The Schneider Electric ABLS1A48100E is a single-phase, DIN-rail mounted regulated switch-mode power supply from the Easy Modicon ABL2 range, delivering 48 V DC at up to 10 A (480 W) from a 100-240 V AC input. It is built for general industrial loads run from a 48 V rail, with an output adjustment potentiometer for cable-drop compensation.
At 10 A / 480 W, the ABLS1A48100E is the highest-power 48 V DC unit in this pairing, sized for a 48 V rail feeding several relay-logic or telecom-style loads from one supply. The 43.2-55.2 V output window and 0.9-0.98 cos phi keep the rail within standard 48 V DC equipment tolerance under continuous industrial duty. Its 80% efficiency at this higher output voltage means more heat is dissipated per watt delivered than the lower-voltage 24 V models in this range, worth accounting for in panel ventilation.
