Siemens 6ES7307-1KA01-0AA0 is the SIMATIC S7-300 stabilized power supply PS307, designed to provide a regulated 24 V DC output for S7-300 controller systems. It accepts 120 or 230 V AC input and delivers up to 10 A of DC current, making it suitable for compact control cabinets where a single, reliable 24 V rail is required. The unit measures 120 x 125 x 120 mm and weighs approximately 1,200 g, reflecting a compact brick-like form factor common to S7-300 PS modules. This particular model is listed by Siemens as End of Product Lifecycle and is no longer generally available through Siemens channels.
