Siemens 6ES7 307-1EA01-0AA0 Power Supply

Siemens PS 307 power supply module, model number 6ES7 307-1EA01-0AA0, converts 120/230 V AC mains to a regulated 24 V DC output rated at up to 5 A for S7-300 PLC systems. The unit is intended for use in Siemens S7-300 racks, delivering a stable 24 V DC to the CPU, I/O cards, and peripheral modules to keep automation processes running reliably. It accepts 120 or 230 V AC with 50/60 Hz input and provides a maximum DC output of 24 V at 5 A (approximately 120 W), making it a fit-for-purpose replacement part in industrial environments where Siemens genuine components are required. The exact 6ES7 307-1EA01-0AA0 designation identifies an PS 307 AC input configuration compatible with the 6ES7 3xxx family, commonly selected to power compact PLC installations, controllers, and expansion modules, ensuring consistent power delivery and compatibility with existing S7-300 infrastructure. In practice, this power supply supports standard manufacturing, packaging, and process-control applications where a dedicated 24 V DC rail is needed to energize the PLC logic and attached devices without introducing voltage irregularities or downtime.
