Product Analysis: 6ES7307-1EA01-0AA0
The Siemens 6ES7307-1EA01-0AA0 is the standard **Load Power Supply (PS 307)** designed specifically for the SIMATIC S7-300 system design. It converts 120/230 V AC mains voltage into a regulated **24 V DC, 5 A** output, powering the CPU and I/O modules via the backplane comb connector.
Key Specifications
- Input Voltage: 120 / 230 V AC (Auto-range switch).
- Output Voltage: 24 V DC (Stabilized).
- Output Current: 5 A.
- Dimensions: 60mm width (Mounts on S7-300 rail).
Reliability
The PS 307 is built to handle industrial fluctuations. It provides protection against short-circuits and open circuits. In the event of an overload, the voltage is reduced to protect connected electronics.
Installation
This power supply mounts directly on the S7-300 mounting rail (leftmost slot). It includes the DC connecting comb to supply power directly to the CPU adjacent to it, eliminating wiring clutter. Essential for every standard S7-300 rack configuration.
