Siemens 6ES7 307-1EA00-0AA0 Power Supply 24 VDC

Siemens 6ES7 307-1EA00-0AA0 PS307 Power Supply Module converts mains AC to a stable 24 V DC output for SIMATIC S7-300 automation systems. With an input range of 120/230 VAC, this unit delivers up to 5 A at 24 V DC, providing the primary energy source for the S7-300 rack’s CPU, I/O modules, and related peripherals. The 6ES7 307-1EA00-0AA0 designation identifies the PS307 variant in the S7-300 family, and Siemens catalogs list it under order number 6ES7307-1EA00-0AA0. As a dedicated 24 V DC supply for the S7-300 backplane, it is designed for stable operation in industrial control panels and automation cabinets where reliable power to the control system is essential. The 24 V DC output is sufficient for typical load scenarios in standard S7-300 configurations, and the PS307 module serves as the power foundation that enables CPU function, I/O scanning, and peripheral communications within the system. In installations requiring a replacement or spare PS307, the 6ES7 307-1EA00-0AA0 variant provides a direct, compatible option for delivering the required 24 V DC at up to 5 A from a 120/230 VAC supply.
