Siemens 6ES7 307-1KA00-0AA0 Regulated Power Supply

Siemens 6ES7307-1KA00-0AA0 PS307 Regulated Power Supply delivers a stable 24 V DC output at up to 10 A from a 120/230 V AC input, specifically designed to power SIMATIC S7-300 PLC systems. As the PS307 regulator module, it is intended to supply the DC power requirements of the S7-300 CPU, I/O racks, and other 24 V DC devices within industrial control panels, providing reliable regulation across typical factory voltage fluctuations. Key specifications include an input range of 120–230 VAC and an output of 24 V DC with a maximum current of 10 A; the part number 6ES7307-1KA00-0AA0 identifies the 10 A PS307 variant used in S7-300 installations. This model appears in Siemens product catalogs and industry listings as the PS307 option for 10 A configurations, reinforcing its role as a dedicated load power supply within the SIMATIC S7-300 ecosystem. Typical applications encompass powering the PLC processor, companion modules, and peripheral 24 V DC devices in control panels and process automation cabinets, where a regulated 24 V supply is essential for deterministic operation and system stability.
