Features:

  • SIMATIC form factor: PM 1507 supply for S7-1500 installations
  • Regulated output: 24 V DC at 8 A for automation loads
  • Wide input choice: documented 120/230 V AC operation
6EP1333-4BA00 provides a dedicated regulated 24 V DC source within a SIMATIC S7-1500 cabinet.

Its 8 A rating must be evaluated against continuous load, startup inrush and downstream protection rather than treated as available margin.

Procurement and commissioning should retain the full catalog, input setting, protection design, current calculation, terminal records and enclosure conditions.

Availability of 6EP1333-4BA00 is subject to Apter Power inventory and sourcing confirmation.

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.

  • Nominal input: verify the 120 or 230 V AC supply arrangement.
  • Branch protection: select upstream protection from the official installation data.
  • Conductors: size wiring and terminals for the documented circuit.
  • Isolation: provide a safe means to de-energize the supply for service.
  • Continuous demand: keep the connected load within 8 A.
  • Inrush: include controllers, I/O and field devices during startup.
  • Distribution: separate protected branches where the cabinet design requires it.
  • Diagnostics: measure output voltage at the supply and critical loads.
  • Placement: maintain the official mounting orientation and clearances.
  • Thermal path: account for enclosure temperature and neighboring heat sources.
  • Service access: keep terminals and protection devices identifiable.
  • Hazardous areas: do not infer Ex approval for this catalog.
  • S7-1500 stations: provide regulated 24 V DC for controller-related loads.
  • Automation cabinets: convert plant AC power for protected DC distribution.
  • Machine controls: supply approved 24 V DC devices within the calculated 8 A budget.
Description
Power planning for a SIMATIC S7-1500 station can place 6EP1333-4BA00 beside the automation hardware as the PM 1507 stabilized supply. Its mechanical alignment and regulated DC output let the cabinet designer keep the controller power source within the documented Siemens system arrangement.

Stable operation from 6EP1333-4BA00 depends on the relationship between line selection, downstream demand, conductor losses and protection. The supply should therefore be evaluated under the station startup and operating sequence instead of from an unloaded output reading.

When 6EP1333-4BA00 is considered for replacement, the engineer should compare the complete article number, line supply selection, load calculation and rail layout with the existing drawing. A correct no-load voltage alone is not enough to demonstrate that the station can start and remain stable.

Technical notes
The decisive boundary for 6EP1333-4BA00 is the absence of Ex approval. Do not assign it to a hazardous-area requirement from enclosure assumptions alone; confirm the installation zone, the project compliance basis, and the permitted cabinet location before the supply is specified or energized in the approved panel design.

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.
When an S7-1500 station restarts as field devices energize, how should 6EP1333-4BA00 be assessed?
Measure its output during the startup event, compare the actual downstream demand with the engineered supply margin, and inspect wiring losses or protection before changing the CPU.
Can 6EP1333-4BA00 be accepted for a hazardous-area cabinet because the enclosure is certified?
Not on that basis. Siemens lists no Ex approval for this supply, so the complete installation compliance path must authorize its location before use.
What should be compared before 6EP1333-4BA00 replaces another cabinet power supply?
Match the incoming supply arrangement, regulated DC load, protection, mounting space, conductor sizes and the S7-1500 station drawing rather than relying on voltage class alone.
Why might 6EP1333-4BA00 show the expected voltage with no load but drop when the station starts?
Excess demand, inrush, wiring resistance, loose terminals or upstream protection can create the loaded condition; test under the actual startup sequence.
How should future module expansion affect a cabinet already powered by 6EP1333-4BA00?
Recalculate continuous and startup demand before adding hardware, preserve design margin, and provide another approved supply if the expanded station exceeds the documented plan.
What receiving check is useful when 6EP1333-4BA00 is intended for an existing S7-1500 panel?
Compare the full article number, terminal condition, mounting interface and traceability with the approved bill of materials before releasing it to the panel builder.
