Siemens 6EP3331-6SB00-0AY0 / 6EP3332-6SB00-0AY0 LOGO!POWER 24 V 1.3 A / 2.5 A Stabilized Power Supplies Item NO.: 2927518

Siemens 6EP3331-6SB00-0AY0 / Siemens 6EP3332-6SB00-0AY0 are LOGO!POWER stabilized power supplies that convert a 100 to 240 V AC feeder into a regulated 24 V DC control supply. The two order numbers perform the same conversion role but provide different current capacity, allowing the connected controller and field circuits to be supplied from one defined DC branch.

Mains power enters Siemens 6EP3331-6SB00-0AY0 / Siemens 6EP3332-6SB00-0AY0 at the input stage, is rectified and regulated, and leaves through the 24 V output terminals. Connected LOGO! hardware and field devices draw current from that output in parallel, so the branch total is the sum of the steady demands rather than the rating of any one device.

Load planning for Siemens 6EP3331-6SB00-0AY0 / Siemens 6EP3332-6SB00-0AY0 compares that total with the selected 1.3 A or 2.5 A output and then accounts for starting current and conductor voltage drop. Short-circuit and overload behavior protects the supply itself, while each downstream conductor and device still requires protection appropriate to its branch.
