Features:
- Comprehensive Protection – Provides short-circuit-proof, open-circuit-proof 24V DC (24V±3%) with built-in electronic protection against short circuits, overloads, and primary undervoltage
- Features 120V/230V AC (50/60Hz) automatic voltage range switching, eliminating manual selectors and ensuring compatibility with global power grids
- Includes green "24V OK" LED for real-time status indication and supports direct S7-300 rail mounting, allowing seamless integration with SIMATIC system components
The 6ES7307-1KA00-0AA0 delivers a regulated 24V DC output with a 10A current rating, capable of powering an entire S7-300 rack including the CPU, multiple I/O modules, and connected field devices such as sensors and actuators . The output is both short-circuit-proof and open-circuit-proof, meaning the module automatically shuts down and recovers without damage when a fault is removed .Its electronic protection system includes current limiting (typically 1.1 to 1.3 × IN) and automatic restart after fault clearance, ensuring system uptime.
Engineered for worldwide deployment, the 6ES7307-1KA00-0AA0 accepts both 120V AC and 230V AC single-phase inputs without requiring manual jumper adjustment or selector switches . The module automatically detects and adapts to the input voltage within ranges of 85-132V (for 120V) and 170-264V (for 230V) . Input frequency tolerance spans 47Hz to 63Hz, accommodating both 50Hz and 60Hz grids. Under full load, the module draws approximately 4.2A at 120V input or 1.9A at 230V input, allowing system designers to plan for upstream circuit protection using standard 10A type-C circuit breakers .
The 6ES7307-1KA00-0AA0 is physically and electrically designed as a dedicated S7-300 system component . Its 80mm width matches the standard S7-300 module form factor, allowing it to be mounted directly on the S7-300 DIN rail as the first (leftmost) module, with the CPU and I/O modules placed to its right. This integrated design eliminates the need for external power distribution wiring. A green LED labeled "24V OK" on the front panel provides immediate visual confirmation of output voltage presence, enabling rapid troubleshooting by maintenance personnel.
The 6ES7307-1KA00-0AA0 Siemens Load Power Supply may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Central Controller Power Supply: Directly mounts on the S7-300 DIN rail to supply stabilized 24 V DC backplane power to S7-300 CPUs, signal modules (SM), communication processors (CP), and function modules (FM).
- Decentralized Remote I/O Nodes: Deployed in ET 200M remote interface sub-racks to power distributed analog/digital modules over PROFIBUS or PROFINET configurations.
- Field Sensor and Actuator Power: Supplies steady 24 V loops to power field instrumentation, inductive sensors, relay coils, pilot lights, and low-power solenoid valves.
- Output Rating: Delivers a rock-solid 24 V DC (±3% tolerance) up to a 10 A continuous load.
- Input Flexibility: Accommodates standard 1-phase AC lines, operating seamlessly across 120 V AC or 230 V AC ranges.
- Energy Efficiency: Achieves approximately 87% operational efficiency at full rated values, minimizing wasted energy and mitigating localized heat dissipation inside tight control panels.
- Mains Buffering: Provides a minimum of 20 ms of mains buffering time to span brief line voltage dips without triggering a PLC system reset or a brownout state.
- High-Density Signal Processing Cabinets: Ideal for S7-300 control nodes containing up to 8 or 16 densely populated 32-channel digital input/output cards, where lesser 2 A or 5 A power modules cannot sustain the cumulative load current.
- Material Handling and Conveyor Loops: Powers decentralized conveyor sections where a single S7-300 station tracks dozens of proximity switches, photo-eyes, and interface relays across a production floor.
- Water/Wastewater Pumping Panels: Serves as the central 24 V DC foundation in outdoor pumping cabinets, sustaining PLC uptime during minor line disturbances and surviving mechanical shock and vibration (up to 15 g).
