Product Description: Siemens 6ES7307-1BA00-0AA0 (PS 307)

The Siemens 6ES7307-1BA00-0AA0 (PS 307) is a compact power supply module for the SIMATIC S7-300 automation system. It converts 120/230 V AC mains to a regulated 24 V DC output capable of supplying up to 5 A to the S7-300 backplane bus. With built-in protections and a slim 40 mm width, the PS 307 ensures reliable power delivery and space-efficient installation in control cabinets.
