Original Siemens 6sn1145 G1 Power Supply Board A5E02026634 A5EO2O26634

Siemens A5E02026634 Power Supply Board

The A5E02026634 is a power supply board built for high-voltage machine or converter assemblies. The stable identifiers tied to this part are 480 V AC, 50/60 Hz, 600 V DC, 0.7–0.9 A, on-board transformers, and dual memory slots.

Across parts listings, it is consistently placed in the PLC / machine control add-on board category and described as a power-supply or power-converter board.

For a product page, the safest and most accurate way to describe this model is as a Siemens internal power supply board for machine-control or converter assemblies where the installed hardware already uses this exact reference.

The available source material does not firmly tie it to one single Siemens product family, so exact label matching is more important here than broader family assumptions.

Technical Data

Application Scenarios

A5E02026634 is most suitable for machine-control power-board replacement and converter-section repair where the installed assembly already uses this same Siemens board.

Because the part is described as a power-supply / converter board with onboard transformers and dual memory slots, it is best matched to systems where the board is part of the internal supply and configuration layer rather than an external signal interface.

Product Replacement Guide

Before replacing A5E02026634, confirm the exact board number, the input power class used by the installed system, and the board’s physical position in the cabinet or converter assembly.

The most important matching points are the 480 V AC / 600 V DC class, the presence of on-board transformers, and the dual memory-slot layout.

If the installed board label includes a secondary code such as EOE13080002, that code should also be checked before ordering.

FAQ

Q1. What type of board is A5E02026634?
It is a power supply board, also described in some listings as a power-converter board in the PLC / machine-control board category.

Q2. What does this board do in the system?
Its role is to provide the internal power-conversion and supply function for the assembly it is installed in.

The part is consistently described as a power-supply board with onboard transformers, which indicates a supply-side role rather than an operator or I/O role.

Q3. What should be checked when selecting A5E02026634?
Check the full part number, the input class of the installed equipment, and whether the current board matches the same transformer and memory-slot layout.

Where present, secondary board markings should also be verified.

Q4. How should the key specifications be understood?

The most important specifications are 480 V AC, 50/60 Hz, 600 V DC, and 0.7–0.9 A. These define the board’s supply environment.

The dual memory slots and on-board transformers are also important identifiers because they help distinguish this board from simpler supply PCBs.

Q5. How should faults be diagnosed before replacing this board?
Start by separating a board-level supply fault from an upstream input problem or a downstream control-board fault.

If the input class matches this board and the issue points to internal power conversion rather than external wiring or a separate CPU card, the power board becomes a stronger candidate.
