Why Engineers Specify This Model
- 10A Output — Sufficient headroom to power a fully populated S7-300 rack plus field I/O loads without derating.
- Auto-Ranging AC Input — Single SKU covers 120 VAC (North America) and 230 VAC (Europe/Asia) installations.
- Integrated Short-Circuit & Overload Protection — Electronic current limiting prevents cascade failures across the 24VDC bus.
- Parallel Operation Ready — Two units can be paralleled for redundant N+1 power architectures in critical applications.
- Direct Backplane Feed — Plugs directly into the S7-300 profile rail bus connector; no external wiring to CPU or SM modules.
- Long Production Lifecycle — Siemens SIMATIC S7-300 platform has an extended support horizon; spare parts availability is well-documented.

Application-Specific FAQ
Q: Can the 6ES7307-1KA01-0AA0 power both the S7-300 backplane and external 24VDC field devices?
A: Yes. The 10A output is shared between the backplane bus and the L+ / M terminals on the front connector. Size your field load budget accordingly — Siemens recommends leaving ≥ 20% headroom.
Q: Is this module compatible with the S7-300 failsafe (F-series) CPUs?
A: Yes. The PS 307 10A is the standard power supply for all S7-300 variants including CPU 315F-2 PN/DP and CPU 317F-2 DP safety controllers.
Q: What is the difference between 6ES7307-1KA01-0AA0 and 6ES7307-1KA02-0AA0?
A: The -0AA0 suffix denotes the standard version; the -0AA2 is a later hardware revision with minor internal improvements. Both are functionally interchangeable as drop-in replacements.
Q: Do you supply the matching S7-300 profile rail and bus connectors?
A: Yes. Contact us with your rack length and slot count for a complete BOM quotation.
Q: Can this unit be used outside a Siemens S7-300 rack as a standalone 24VDC PSU?
A: Technically yes — the L+ / M terminals provide regulated 24VDC. However, it is optimized for S7-300 rail mounting and backplane power delivery.
