Siemens 6ES7307‑1EA00‑0AA0 SIMATIC S7‑300 Regulated Power Supply Module
Product Overview
The Siemens 6ES7307‑1EA00‑0AA0 is a dedicated regulated switching‑mode power supply module designed for the SIMATIC S7‑300 PLC system. It provides stable 24 V DC power for S7‑300 CPU units, signal modules, communication modules, sensors, relays and other field devices installed on the S7‑300 rack. This power supply is specially engineered for rack‑mount installation on the S7‑300 backplane bus, featuring high efficiency, complete protection functions and industrial‑grade stability. It is widely used in medium‑and‑large‑scale industrial automation such as process control, machinery manufacturing, energy systems and factory production lines.
Main Functions
- Stable 24 V DC Power Output
Converts single‑phase AC input into regulated 24 V DC power to supply the entire S7‑300 rack system and peripheral low‑voltage loads.
- Wide‑Range AC Input Compatibility
Supports global standard single‑phase AC input voltage, adapting to unstable industrial power grid environments.
- Comprehensive Protection Mechanisms
Integrates short‑circuit protection, overload protection, over‑voltage protection and over‑temperature protection to safeguard the power supply and connected PLC modules.
- Backplane Bus Power Supply
Supplies power to the S7‑300 U‑rail backplane bus directly, ensuring stable communication and operation of all rack‑mounted modules.
- High‑Efficiency Operation
Low heat generation and low power loss, suitable for long‑term continuous 24‑hour operation inside control cabinets.
- Modular Rack‑Mount Design
Installs directly on the S7‑300 standard U‑rail, matching the size and mechanical structure of other S7‑300 modules.
Technical Characteristics
- Switch‑mode power supply design with high energy efficiency and low standby power consumption.
- Perfect mechanical and electrical compatibility with all SIMATIC S7‑300 series modules.
- Industrial‑grade electromagnetic interference resistance for stable operation in harsh factory environments.
- Automatic recovery function after fault elimination, supporting unattended continuous operation.
- Compact modular structure, easy for installation, wiring and maintenance.
- Wide operating temperature range and strong vibration resistance for industrial cabinet applications.
