The Siemens 6EP3310-6SB00-0AY0 is a LOGO!Power stabilized DIN-rail power supply converting 100-240 V AC (85-264 V wide-range) input to a regulated 5 V DC output at up to 3 A. It delivers 76% efficiency, short-circuit-proof output, and a 40 ms power-failure buffering time, housed in a 36 x 90 x 53 mm enclosure.
The 5 V / 3 A output size matches low-current logic and sensor loads, such as a LOGO! basic unit or 5 V-powered instrumentation, rather than the higher-current 24 V DC rail supplying contactors and larger I/O; pick a 24 V SITOP unit instead when the load is standard industrial 24 V equipment. The 40 ms power-failure buffering and short-circuit-proof output let it ride through brief dips without a dedicated UPS on small control panels.
Powers 5 V DC logic circuits, sensor rails, and small instrumentation on DIN-rail control panels, typically alongside a LOGO! or S7 controller drawing 24 V from a separate supply.
