Key Features

• 10A High Output: Delivers 240W of total power, capable of supporting high-density S7-300 configurations and external field devices.
• S7-300 Rail Compatibility: Specifically designed to mount on the S7-300 profile rail and connect mechanically with the CPU via a special power connector.
• Wide-Range Input: Supports single-phase AC input (120V / 230V AC) with an automatic range switch for global industrial use.
• Comprehensive Protection: Features short-circuit and overload protection with automatic restart, ensuring the safety of the attached PLC components.
• High Efficiency: Optimized thermal design ensures minimal heat generation within the control cabinet, extending the lifespan of neighboring modules.
• Electrical Isolation: Provides safe galvanic isolation according to SELV (Safety Extra-Low Voltage) standards.
• Diagnostic LED: A front-facing green LED provides immediate visual confirmation of the 24V DC output status.

Item Condition (Used - Working)

• Functional Status: Used - Working. This power supply has been professionally removed from an active SIMATIC S7-300 rack. It has been bench-tested under load to verify a steady 24V DC output and proper voltage regulation.
• Physical State: Good industrial condition. The casing shows typical signs of installation on a profile rail. All terminal screws are in good condition and turn freely.
• Technical Integrity: No evidence of overheating or electrolytic leakage. The unit operates silently and within factory temperature specifications.
• Visual Reference: Please refer to the high-resolution images to confirm the hardware version; the unit pictured is the exact 6ES7307-1KA01-0AA0 you will receive.
