Siemens 6ES7 307-1EA00-0AA0 Power Supply Module

Siemens 6ES7 307-1EA00-0AA0 PS307 Power Supply Module for the SIMATIC S7-300 family converts 120 or 230 VAC input into 24 VDC at up to 5 A to power the rack backplane and connected I/O modules. The PS307 variant delivers a fixed 24 V DC output rated at 5 A, making it suitable for mid-range S7-300 configurations that require a reliable DC rail to feed the CPU, I/O, and associated circuitry. This power supply is designed to function within Siemens’ S7-300 ecosystem, supporting installations where the AC source is either 120 VAC or 230 VAC and the total DC load remains within the 5 A rating; ensure compatibility with the rack backplane and other PS-series modules in the same chassis. With the 6ES7 307-1EA00-0AA0 designation, this module is explicitly the PS307 24 V DC power source for S7-300 systems and should be selected based on the system’s DC demand and available AC supply to maintain stable operation of the PLC CPU and I/O throughout the automation installation.
