Siemens 6EP1333-2AA01 Power Supply UNMP Module

Siemens 6EP1333-2AA01 SITOP Smart 120 W power supply module delivers a regulated 24 V DC output at up to 5 A from a DIN-rail mounted enclosure. It accepts 120/230 V AC input and is rated IP20 for installation inside control cabinets. The compact unit measures about 50 x 125 x 125 mm and is designed for DIN-rail mounting to simplify integration with SITOP devices, PLCs, and small I/O modules. With a 120 W rating, it provides a steady 24 V DC supply at 5 A continuous, making it suitable for compact automation cabinets and single-branch power needs. Siemens lists the model under the SITOP Smart family and notes its lifecycle as PM500 with sales halted on 2025-04-01; successors include 6EP1333-2BA20 and SITOP PSU100S 24 V/5 A for updated designs. Distributor catalogs commonly reference the 6EP1333-2AA01 for DIN-rail installations, including typical input current values around 2.1 A at 120 V and 1.15 A at 230 V. This power module is an appropriate choice when a compact, stabilized 24 V supply is required to feed PLCs and related automation peripherals within Siemens-based control architectures.
