Siemens 6EP1333-2AA01 Industrial Power Supply

Siemens 6EP1333-2AA01 SITOP SMART 120 W stabilized power supply accepts 120/230 V AC input and delivers 24 V DC at up to 5 A, providing 120 W of regulated power for industrial control panels and automation equipment. As part of the SITOP SMART line, this DIN-rail mounted module features an IP20 enclosure for installation inside control cabinets and is designed to supply reliable 24 V DC power to PLCs, sensors, actuators, and other automation devices in harsh factory environments. The unit draws roughly 1.15 A from a 230 V AC supply (about 2.1 A at 120 V AC) and Siemens lists the model as discontinued as of April 1, 2025, with a recommended successor in the SITOP PSU100S family offering 24 V/5 A. Although discontinued, the 6EP1333-2AA01 remains referenced in legacy installations and documentation for 24 V systems, and the SITOP SMART 120 W platform continues in newer forms with updated features and improved efficiency in the PSU100S lineup.
