FAQ

Is this power supply compatible with the S7-400 series?

No, the PS 307 (6ES7307-1BA00-0AA0) is specifically designed for the SIMATIC S7-300 mounting rack. The S7-400 series requires its own dedicated power supply modules with a different form factor.

The PS 307 has electronic short-circuit and overload protection. While it can handle brief inrush currents, continuous operation above the rated 2A is not recommended and will cause the protection to trip, shutting down the output to protect the connected modules.

The "E-Stand" or "Erzeugnisstand" indicates the hardware revision of the module. E-Stand 1 is an early hardware version of this model. While functionally identical for most applications, later revisions might have minor internal component updates. Compatibility is generally maintained across revisions.
