Why Engineers Specify This Model
- Dual-voltage input flexibility – Switchable 120/230V AC input allows deployment in North American and European facilities without hardware changes.
- Compact 50mm width – Minimizes DIN rail footprint in space-constrained control cabinets while delivering full 2A output.
- Integrated short-circuit & overload protection – Eliminates the need for external fusing on the 24V DC bus, reducing BOM complexity.
- Direct S7-300 backplane compatibility – Snaps onto the standard S7-300 profile rail and connects directly to the CPU/IM bus connector without additional wiring.
- Proven MTBF in harsh environments – Siemens PS307 series is field-validated in foundries, chemical plants, and outdoor enclosures worldwide.

Application-Specific FAQ
Q: Can the 6ES7307-1BA00-0AA0 power a CPU 315-2 DP and two SM modules simultaneously?
A: Yes. The CPU 315-2 DP draws approximately 0.8A from the 24V bus; two standard SM modules add roughly 0.4A total, keeping the system well within the 2A rated output.
Q: Is this power supply compatible with the S7-300 ET 200M distributed I/O head station?
A: Yes. The PS307 2A is the standard power supply for ET 200M racks using IM 153-x interface modules.
Q: What is the difference between 6ES7307-1BA00-0AA0 and 6ES7307-1EA00-0AA0?
A: The 1BA00 variant provides 2A / 48W output; the 1EA00 variant provides 5A / 120W output. Select based on total rack current consumption.
Q: Can this module be used outside a SIMATIC S7-300 rack as a standalone 24V DC power supply?
A: Technically yes — the 24V DC output terminals are accessible — but it is optimized and warranted for use within the S7-300 system architecture.
Q: Does Konmask.com provide a warranty on this module?
A: Yes. We offer a 12-month warranty covering manufacturing defects. Contact support@konmask.com for warranty claims.
