Siemens 6ES7307-1EA01-0AA0 Power Supply Module

Siemens 6ES7307-1EA01-0AA0 is a DIN-rail mounted, regulated power supply module in the SIMATIC S7-300 family. As the PS307 model, it accepts 120/230 VAC input and provides a stabilized 24 V DC output rated at 5 A, powering the S7-300 controller backplane and attached I/O modules. This module’s compact 24 V DC supply is designed for Siemens S7-300 cabinets, delivering a reliable single-source power feed for the CPU and expansion cards in industrial control panels. Typical applications include small to mid-size DIN-rail control panels where a dedicated 24 V DC supply supports the CPU, digital and analog I/O modules, and additional PS307-compatible peripherals. Verified specifications for this exact part number include input 120/230 VAC, output 24 V DC, and maximum output current 5 A. The PS307 family is built to provide regulated power to S7-300 systems, enabling stable operation across the rack and consistent voltage delivery to all modules.
