Why Engineers Specify This Model
- Plug-and-Play S7-300 Integration – Slots directly onto the S7-300 profile rail and connects to the backplane bus without additional wiring adapters.
- Wide AC Input Range – Dual 120/230V AC selection handles both North American and European grid standards, simplifying global machine builds.
- Regulated, Low-Ripple Output – Stabilized 24V DC output protects sensitive CPU and I/O modules from voltage transients that cause spurious faults.
- Compact 50 mm Width – Minimizes DIN rail footprint in space-constrained control cabinets; ideal for distributed rack architectures.
- Electronic Short-Circuit Protection – Auto-restart behavior eliminates manual intervention after transient overloads, reducing unplanned downtime.
- Proven Siemens Reliability – Part of the mature SIMATIC S7-300 ecosystem with decades of field validation across millions of installed nodes worldwide.

Application-Specific FAQ
Q: Can the 6ES7307-1BA00-0AA0 power both the S7-300 backplane and external 24V field devices?
A: The 2A output (48W) is sized primarily for the S7-300 rack (CPU + I/O modules). For powering external sensors and actuators simultaneously, a separate 24V field power supply is recommended to avoid overloading the PS307.
Q: Is this power supply compatible with the S7-300 ET 200M distributed I/O?
A: Yes. The ET 200M uses the same S7-300 profile rail and PS307 power supply family. The 6ES7307-1BA00-0AA0 is a valid power source for ET 200M racks with moderate I/O loads.
Q: What is the difference between 6ES7307-1BA00-0AA0 and 6ES7307-1EA00-0AA0?
A: The -1BA00 variant delivers 2A / 48W output; the -1EA00 delivers 5A / 120W. Select the -1EA00 for larger racks with high-density analog or communication modules that draw more current.
Q: Can I use this PSU in a 24V DC input application (e.g., powered from a UPS)?
A: No. The 6ES7307-1BA00-0AA0 requires AC input (120/230V). For DC-input applications, refer to the SITOP PSU series (e.g., 6EP1332-1SH52).
Q: Does Konmask.com provide a warranty on this part?
A: Yes. New units carry the standard Siemens manufacturer warranty. Refurbished units include a 90-day Konmask functional warranty. Contact us for full warranty terms.
