What the LOGO!Power 6EP1331-1SH01-0AA1 actually does
The Siemens 6EP1331-1SH01-0AA1 is a member of the LOGO!Power line — a stabilized switching power supply that takes a wide-range 120-230 V AC input and delivers a regulated 24 V DC output at 1.3 A, which works out to roughly 30 W of usable 24 V bus for a small control cabinet. It is the kind of PSU panel builders drop next to a LOGO! 8 base module when the downstream loads are a handful of relays, a small HMI, or a few sensor clusters rather than a full PLC rack.
Sizing and fit in a real 24 V cabinet
1.3 A at 24 V is the budget ceiling for the whole downstream 24 V bus — a single LOGO! 8 base plus a couple of digital expansion modules, a 4-line HMI backlight, and a string of relay coils typically lands inside that envelope; a stack that includes any frequency inverter or larger valve manifold does not. Plan the load before specifying this supply, because the output current, not the input voltage range, is the figure that gets rejected on a panel-builder punch-list when the cabinet is commissioned. The 120-230 V AC input window covers both 120 V and 230 V nominal feeds without a tap-change, which simplifies stocking for panels that ship into either North-American or European sites off the same BOM. For plants on 100 V Japanese feeds or 240 V British legacy rails, verify the actual measured nominal before mounting — the wide-range spec is not the same as universal.
Production status and how it is sourced
Standard orders on this code typically land inside a one-to-ten working-day window, which is the window quoted for the listing. For larger BOM quantities the lead time is confirmed per RFQ — that is the right place to push for a firm date rather than assume the catalog figure holds at volume.
