Siemens 6ES7 307-1KA01-0AA0 Power Supply Module

Siemens 6ES7307-1KA01-0AA0 PS307 power supply module converts 120/230 V AC input to a stable 24 V DC output up to 10 A for SIMATIC S7-300 installations. The unit accepts 120 or 230 V AC mains and delivers a regulated 24 V DC rail capable of supplying the CPU, memory, and I/O modules that form the backbone of a typical S7-300 automation rack. As part of the SIMATIC S7-300 power architecture, the PS307 provides the primary DC supply to the backplane, enabling reliable operation of controllers and connected field devices in industrial environments. It's designed for use within the S7-300 family and is commonly installed on the same chassis as CPU modules to ensure a consistent DC reference across the system. Common applications include powering the S7-300 CPU and I/O modules in manufacturing lines and process-control installations. The PS307 10 A output is designed to meet the current demands of mid-range S7-300 configurations while staying within the backplane's power budget.
