Siemens 6ES7307-1EA01-0AA0 SIMATIC S7-300 PS 307 Power Supply
01Product Identification
Siemens 6ES7307-1EA01-0AA0 is a regulated SIMATIC S7-300 PS 307 power supply with selectable 120 or 230 V AC input and a 24 V DC, 5 A output. It is part of the one-phase 24 V DC supply family for S7-300 and ET 200M installations.
02Key Features
Design and Functions
- Regulated 24 V DC output supplies compatible automation loads.
- Selectable 120 or 230 V AC input supports documented industrial mains systems.
- The 5 A output class is intended for appropriately calculated S7-300 or ET 200M load demand.
- Front-panel status and protective behavior support cabinet troubleshooting.
- Module format aligns with the original SIMATIC installation concept.
- Exact article-number control prevents confusion with other PS 307 current ratings.

04System Integration
- Confirm the complete 6ES7307-1EA01-0AA0 model identity against the installed nameplate and project documentation.
- Verify that the simatic s7-300 ps 307 regulated power supply is supported by the installed hardware platform and engineering software.
- Check field wiring, supply conditions, terminal assignments, protective devices, and required environmental or hazardous-area approvals.
- Preserve the approved configuration, scaling, alarms, diagnostics, addresses, and maintenance records before equipment exchange.
- Complete point-to-point checks and an approved functional commissioning test before returning the process to service.
05Applications
- SIMATIC S7-300 rack and field-circuit power.
- ET 200M station supply within the documented load limit.
- Industrial control cabinets requiring regulated 24 V DC at 5 A.
- Legacy maintenance where the exact PS 307 input and output class must be preserved.
06Lifecycle
- Siemens lists product phase-out from 1 October 2023.
- Confirm mains selection, protective devices, grounding, conductor sizes, and total 24 V DC load.
- Record all downstream loads and verify inrush demand before replacement.
- After installation, confirm output voltage under load and review controller or I/O diagnostics.
- Do not substitute a different current rating without checking dimensions, wiring, protection, thermal conditions, and system design.
