Overview Manuals Input Protection Output Behavior Thermal Mounting Product Applications

Features:

  • Regulated control power: 24 V DC at 5 A supplies industrial automation loads
  • Panel integration: DIN-rail construction includes an adjustable output and status contact
  • Documented service boundary: mains selection, protection, spacing, and parallel rules require verification
6EP1333-2AA01 provides a dedicated 120 W control-power stage between AC mains and a 24 V DC automation bus.

Its service value depends on correct input selection and a load plan that respects current, inrush, ventilation, and parallel-operation rules.

A replacement assessment should retain the supply-voltage record, protective device, wire sizes, output setting, load inventory, alarm contact, and cabinet temperature.
Apter Power can review 6EP1333-2AA01 mains, load, protection, mounting, condition, and successor-comparison requirements before sourcing.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Mains selection: set the documented input range before applying 120 or 230 V AC.
  • Branch device: coordinate the upstream fuse or circuit breaker with the official installation guidance.
  • Inrush allowance: include startup current when selecting switching and protective components.
  • Voltage setting: adjust the DC output only within the documented range.
  • Load control: keep continuous current within the 5 A rating and account for connected-device startup demand.
  • Parallel use: follow the stated wiring and adjustment conditions when supplies share a load.
  • DIN-rail position: mount the unit in the prescribed orientation.
  • Air clearance: preserve the manual-defined spacing around neighboring equipment.
  • Temperature review: compare cabinet ambient and heat sources with the published operating limits.
  • PLC control power: supply a documented 24 V DC load group within the 5 A rating.
  • Sensor and relay circuits: power cabinet field-interface loads from a regulated source.
  • Maintenance replacement: restore an existing SITOP circuit after mains, load, protection, and space are verified.
Description
6EP1333-2AA01 is a Siemens SITOP smart regulated power supply rated for 120/230 V AC input and 24 V DC, 5 A output. The 120 W DIN-rail unit provides the control-voltage source used by PLC, sensor, actuator, and interface circuits within its documented load limits.

The output of 6EP1333-2AA01 can be adjusted within the published range, and its signaling contact supports status supervision. The manual also defines parallel operation, protective-device selection, installation spacing, and ambient-temperature conditions that affect a reliable panel design.

When replacing 6EP1333-2AA01, verify input-voltage selection, conductor sizing, branch protection, load current, inrush behavior, heat clearance, and output adjustment. Siemens identifies a successor catalog, but migration still requires electrical and mechanical comparison.

Technical notes
Before energizing 6EP1333-2AA01, match the input selector to the connected mains supply and confirm branch protection, conductor size, ventilation, and total 24 V load. A wrong selector position or overloaded parallel arrangement can damage the supply; measure output voltage and current before reconnecting sensitive control equipment.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can 6EP1333-2AA01 trip its upstream protection during an otherwise normal startup?
Compare the selected protective device with the documented inrush current and mains condition, then separate supply startup from downstream load pickup before increasing the breaker or fuse rating.
What should be checked when 6EP1333-2AA01 shows 24 V with no load but drops after the cabinet is connected?
Measure total steady and startup current, inspect conductor voltage drop and loose terminals, isolate load branches, and verify that parallel supplies share the output only under the documented conditions.
How should parallel operation of 6EP1333-2AA01 be commissioned?
Match output settings before coupling the supplies, use the prescribed conductor arrangement, verify current sharing under the real load, and test the signaling contacts without exceeding the combined wiring and protection limits.
Why can 6EP1333-2AA01 become unstable after another heat-producing device is installed nearby?
The new thermal load can raise local ambient temperature or block ventilation. Measure air around the supply, restore required clearances, confirm mounting orientation, and retest output under maximum expected panel load.
Does the Siemens successor for 6EP1333-2AA01 permit a direct swap without review?
No automatic equivalence should be assumed. Compare input range, output behavior, terminals, dimensions, protection, signaling, mounting clearance, approvals, and the connected load before approving migration.
What information makes a 6EP1333-2AA01 purchase request technically complete?
Include nameplate photographs, mains voltage, load current and startup demand, upstream protection, output setting, cabinet temperature, quantity, condition, destination, and required delivery date.
