Industrial 24 V DC supply designed for the stated SIMATIC IPC generations.
Product Overview
A5E30947477-H4 is the H4 revision of Siemens article A5E30947477, an industrial 24 V DC power supply rated at 150 W for selected SIMATIC industrial PCs.
Siemens lists compatibility with SIMATIC IPC627B/C, IPC827B/C, HMI IPC677B/C, HMI IPC577B and HMI IPC577C. The installed computer generation and the full H4 label must be checked before exchange.
The product is in the Siemens cancellation lifecycle, so replacement work should preserve the host identity, connector arrangement and removed-unit revision record.

FAQ
What should accompany an A5E30947477-H4 enquiry?
Send the complete power-supply label, SIMATIC IPC or HMI IPC model, machine nameplate, connector photographs, required quantity and destination.
Can A5E30947477-H4 be selected only from the 24 V and 150 W ratings?
No. Match the supported IPC generation, connector arrangement, mechanical envelope and the full H4 revision identity.
How should a stored A5E30947477-H4 spare be protected?
Use ESD-safe, dry storage with connector protection and retain the original identification and inspection record.
What lifecycle point matters for A5E30947477-H4?
Siemens marks the base article as cancelled, so availability, repair options and any controlled migration should be reviewed before a shutdown.
What proves A5E30947477-H4 is ready for service?
Confirm correct host and revision, stable IPC startup, normal peripheral operation, no supply diagnostics and a documented controlled shutdown test.
