Overview
The Siemens 6ES7 307-1EA00-0AA0 is a regulated DC power supply module for SIMATIC S7-300 PLC systems. This PS 307 model converts single-phase AC input (120/230V, 50/60 Hz) to stable 24V DC output at 5A, providing the clean, regulated power essential for reliable PLC and I/O module operation. With built-in short-circuit and open-circuit protection, this power supply is a drop-in replacement for standard S7-300 power supply applications across manufacturing, process control, and industrial automation.
