Description

The Siemens 6ES7307-1BA00-0AA0 serves as a dedicated load power supply for the SIMATIC S7-300 PLC system. This PS307 module converts incoming alternating current into a stable 24V DC output. Consequently, it provides the necessary energy for CPUs and connected I/O modules. The unit features a narrow design to optimize space within the S7-300 mounting rail. Its robust construction ensures consistent performance in demanding factory environments.

This power supply automatically switches between 120V and 230V AC input ranges. Therefore, engineers can deploy the module in various international power grids without manual adjustments. The internal regulation circuitry protects the sensitive electronics of the PLC from voltage fluctuations. Furthermore, the 2-ampere output capacity supports standard control configurations effectively.

Key Technical Specifications

Operational Features and Design

The PS307 module utilizes a fanless convection cooling system for silent and maintenance-free operation. Additionally, the front panel includes a green LED to indicate healthy output voltage status. The terminal blocks offer secure screw-type connections for both input and output wiring. Because the module belongs to the SIMATIC family, it integrates perfectly with S7-300 CPU racks.

Short-circuit protection comes integrated as a standard safety feature of the 6ES7307-1BA00-0AA0. This prevents damage to the power supply and connected modules during electrical faults. Moreover, the unit provides reliable galvanic isolation between the primary and secondary circuits. This isolation enhances the overall electromagnetic compatibility of the entire automation system.

Industrial Applications

• Primary power source for SIMATIC S7-300 programmable logic controllers.
• Reliable DC energy supply for sensors and small actuator loads.
• Power distribution within localized machine control cabinets.
• Integration into modular automated assembly and packaging lines.
