Product Precautions
- Siemens A5E30947477-H4 supplies internal circuits in the applicable SIMATIC industrial PC rather than a general-purpose cabinet load.
Product type: Industrial PC power supply
Spare-part reference: A5E30947477
Revision: H4
Power conversion: 24 V DC input; 150 W output
Spare-part reference: A5E30947477
Revision: H4
Power conversion: 24 V DC input; 150 W output
Siemens A5E30947477-H4 is a revision-controlled power-supply spare for SIMATIC industrial computers. It accepts a nominal 24 V DC input and has a rated output power of 150 W. Its role is internal power conversion within the intended host computer, rather than supplying general cabinet loads from a standalone 24 V output. Keeping the A5E30947477 reference and H4 revision together helps distinguish the offered assembly during maintenance and spare-parts planning.
Applicable computer references include IPC627B/C and IPC827B/C, together with HMI IPC677B/C and IPC577B/C. The supply supports servicing of these computer installations when the exact host execution and spare-part allocation match.
The installed harness, power connectors, fastening and grounding arrangement remain part of the host-specific assembly. Replacement planning should therefore consider the complete computer configuration and its service instructions, followed by checks of startup, diagnostics and connected peripherals.

-
Box-PC maintenance
Restore power conversion in an applicable IPC627B/C or IPC827B/C installation. Compare the original spare-part reference and hardware revision. -
Panel-PC servicing
Maintain the power-supply assembly in an applicable HMI IPC677B/C or IPC577B/C. Verify the installed unit and its harness before replacement. -
DC-powered computer cabinets
Use the supply within its intended SIMATIC PC installation. Confirm the host DC connection and protective measures from the host instructions. -
Revision-controlled spare planning
Retain A5E30947477 and H4 together in the service record. Verify revision suitability and connectors rather than relying on the base number alone.
Match A5E30947477-H4 to the installed hardware and approved configuration before replacement or commissioning.
Retain the H4 revision
Record the full A5E30947477-H4 marking and compare it with the installed assembly before removal.
Use the intended host
Check the exact SIMATIC PC execution and spare-part allocation. The 150 W rating alone does not establish mechanical or electrical compatibility.
Isolate the computer
Shut down the application, disconnect the source and follow the host service procedure before opening the enclosure.
Distinguish input from output
The nominal 24 V DC value describes the input. Do not interpret this spare as a general-purpose 24 V, 150 W cabinet-output supply.
Preserve internal connections
Record and restore the original power harness, fastening and grounding arrangement. Do not improvise connector pin assignments.
Verify computer operation
After correct reassembly, check startup, diagnostics, connected peripherals and normal application operation under the approved test procedure.
