Why Engineers Specify This Model
- Plug-and-Play Rack Integration — Mechanically and electrically mates with the S7-300 backplane; no external wiring harness required for bus power.
- Wide-Range AC Input — Accepts 120 VAC (North America) and 230 VAC (Europe/Asia) without manual switching, simplifying global machine builds.
- Short-Circuit & Overload Protection — Built-in electronic protection prevents cascade failures across the PLC rack during fault conditions.
- Compact 50 mm Width — Minimises rack footprint, preserving slots for additional I/O or communication modules.
- Long Production Lifecycle — Siemens SIMATIC S7-300 components maintain extended availability and spare-parts support, reducing lifecycle risk for installed base.
- Diagnostic LED — Green DC-OK indicator provides at-a-glance power status without requiring a multimeter or HMI access.

Application-Specific FAQ
Q: Can the 6ES7307-1BA01-0AA0 power both the S7-300 CPU and field devices simultaneously?
A: The PS307 2A supplies 24 VDC to the S7-300 backplane bus. Field devices (sensors, actuators) requiring 24 VDC should be powered from a separate dedicated PSU to avoid overloading the 2 A output and to maintain electrical isolation between control and field circuits.
Q: What is the difference between 6ES7307-1BA01-0AA0 and 6ES7307-1EA01-0AA0?
A: The -1BA01 variant provides 2 A / 48 W output, while the -1EA01 provides 5 A / 120 W. Select the 5 A model when powering larger racks with multiple I/O modules or when field devices are powered from the same supply.
Q: Is this power supply compatible with S7-400 or S7-1500 racks?
A: No. The PS307 is mechanically and electrically designed exclusively for the S7-300 rack system. S7-400 requires PS407 series; S7-1500 uses PM70/PM190 system power modules.
Q: Can I use this unit in a UL 508A-certified control panel?
A: Yes. The 6ES7307-1BA01-0AA0 carries UL/cUL listing under UL 508, making it suitable for inclusion in UL 508A industrial control panels in North America.
Q: What is the typical lead time for this part?
A: In-stock units ship within 1–2 business days. For out-of-stock situations, typical lead time is 5–15 business days depending on sourcing channel. Contact us for real-time availability.
