SITOP / CONTROL POWER CONVERSION
PSU300M 24 V DC / 20 A
The Siemens 6EP1436-3BA10 is a SITOP PSU300M stabilized power supply for a 400 to 500 V three-phase AC network. It provides a 24 V DC output rated at 20 A and supports 50/60 Hz operation within the documented 47 to 63 Hz range. Siemens identifies the product as discontinued since 1 September 2021 and in the final year of support phase. For maintenance purchasing, verify the full order code, input network, output rating, terminal arrangement, available panel space and downstream load demand before installation. Stockoems commercial condition and availability remain separate from the manufacturer lifecycle status.
Condition, availability and warranty are Stockoems commercial information, not manufacturer commitments.
THREE-PHASE INPUT
Confirm network voltage, frequency, protection and isolation.
REGULATION STAGE
The stabilized supply converts mains power for control loads.
DC OUTPUT
Verify conductor sizing, load demand and distribution protection.
Review the complete control-power circuit before replacement. This unit is designed for a three-phase AC input and a stabilized 24 V DC, 20 A output. Confirm electrical protection, terminal wiring, cabinet cooling and load behavior before energizing.

The PSU300M converts a three-phase AC supply into stabilized 24 V DC control power. Its 20 A rated output is intended for engineered industrial power distribution where network conditions, protection and downstream loading are defined in the electrical design.
A power-supply replacement requires more than matching voltage alone. Confirm input phases, frequency, protective devices, terminal allocation, conductor size, panel clearances, thermal conditions and the startup current of connected loads before commissioning.
Match the complete 6EP1436-3BA10 order code, three-phase 400 to 500 V AC input and 24 V DC, 20 A output. Siemens marks this exact product discontinued, so assess mounting, wiring, protection and approved replacement planning before any change.
Siemens specifies a three-phase AC supply with a rated range of 400 to 500 V. Confirm the actual network and protective design.
The unit provides a stabilized 24 V DC output rated at 20 A. Evaluate continuous load, startup demand and distribution protection.
The official technical data identifies 50/60 Hz operation with a 47 to 63 Hz range.
No. Match the full suffix, input phases and voltage, output current, terminals, dimensions, protection and thermal conditions.
No. A successor designation does not remove the need to verify dimensions, wiring, protection, load behavior and project approval.
Yes. Siemens states that this exact model has been discontinued since 1 September 2021 and lists it in PM490, the final year of support.

STOCKOEMS / PROCUREMENT ROUTE
Our service route connects product identification, order evidence, protective handling, logistics and after-sales communication. Scope and timing are agreed for the actual order without promising an unverified inventory quantity or delivery date.
We compare the complete order code with the inquiry and available label photographs.
The written offer identifies the stated condition and available packaging evidence.
Customer system details are reviewed as purchasing support; final approval remains with the responsible engineer.
Available photographs help align the quoted item, visible label and included scope.
Packaging is selected for the component and planned transport route.
Destination, carrier options and shipment requirements are coordinated for the actual order.
Tracking information is shared after the carrier makes it available.
Agreed commercial and shipping documents are prepared for the destination requirements.
Coverage, duration and evidence requirements are stated in writing.
Contact our team and obtain authorization before returning equipment.
Order records, photographs and issue details are reviewed through one sales contact.
Inspection expectations, label checks and the supply scope are recorded before shipping preparation.
Protective handling, shipment details, tracking and documentation remain connected to the order record.
Request the complete model and suffix, actual item and label photographs, a written condition statement, included accessories, warranty terms and shipping scope.
Check consistency across the legal company name, quotation, invoice and payment beneficiary. Confirm named contacts, written order handling, shipment terms and return procedures.
Verify the exact suffix, three-phase 400 to 500 V AC input, 24 V DC and 20 A output, terminals, protection, panel space, thermal conditions and load behavior.
Investigate inconsistent labels, reused or unclear photographs, vague condition language, unexplained payment-detail changes, missing written terms or pressure to pay before evidence is supplied.
No. Ask what was inspected, which item was checked, the test method and its limits. A visual review does not establish electrical function or system compatibility.
Obtain written coverage, exclusions, evidence requirements, time limits and the return authorization procedure before purchasing. Keep the quotation, photographs and delivery record together.
