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

Siemens 6ES7307-1EA01-0AA0 PLC Power Supply Module (PS 307) provides regulated 24 V DC power for SIMATIC S7-300 racks, delivering ~120 W nominal with a typical output current of ~5 A to support CPUs and I/O modules. It accepts 120/230 VAC input (model dependent) and uses a backplane interface for the S7-300 rack, designed for mounting in industrial control panels and machine automation enclosures. The module features IP20 protection, overload and short-circuit protection, and a DC-OK LED indicator to confirm stable power delivery. Common applications include powering PLC CPUs and digital/analog I/O modules across manufacturing lines, process control systems, material handling equipment, packaging machinery, and building automation.
