The Siemens 6AG1332-1SH71-7AA0 is a 2.5 A rated DC power supply from the SITOP family. If you're sorting a pallet of industrial gear, this one's a straight-up workhorse for standard DC bus applications—83% efficient, and it'll run on 120 or 230 VAC without a second thought. Input accepts 85–132 VAC or 176–264 VAC at 47–63 Hz, with automatic range selection. Output is a controlled, isolated DC voltage rated continuously at 2.5 A. Mounting is quick: snap onto DIN rail EN 60715 35x7.5/15 or wall mount. Clearance is tight—20 mm top and bottom for airflow, 0 mm left and right—so it fits flush in a crowded panel. IP20 protected, CE marked, and compliant with EN 55022 Class B emissions plus EN 61000-6-2 immunity—keeps noise out of sensitive controls.
