Features:
- Bridge Between Wide-Range AC Input and S7-400 Rack Backplane
- Integrates Universal AC/DC Power Conversion with Stable 5V DC Output
- Functions Seamlessly with SIMATIC S7-400 CPUs and I/O Modules
The SIEMENS 6ES7407-0KA02-0AA0 SIMATIC S7-400 Power Supply Module serves as the primary power source in an S7-400 rack, delivering dependable 5 V DC power at 10 A to all modules installed in the system. It continuously transforms incoming AC power (120/230V UC wide range) into precisely regulated 5 V DC and channels this power through the rack backplane to maintain consistent operation of all CPUs, communication processors, and I/O modules. Reliable power distribution is inherent to the 6ES7407-0KA02-0AA0, with its robust design ensuring continuous power delivery to critical automation components. The 6ES7407-0KA02-0AA0 incorporates advanced features including primary/secondary potential separation and compliance with IEC 61000-3-2 and IEC 61000-3-3 standards for harmonic distortion limits.
The 6ES7407-0KA02-0AA0 delivers fundamental power functions essential to the entire rack, serving as a vital element of the control system architecture that directly influences the proper, normal operation of the overall S7-400 automation system. One 6ES7407-0KA02-0AA0 power supply is required per rack, with the module occupying two slots in the rack configuration. The 6ES7407-0KA02-0AA0 is designed for straightforward installation within the standard S7-400 rack structure.
For applications requiring enhanced reliability, the S7-400 system architecture allows for careful power planning with the 6ES7407-0KA02-0AA0. The module operates within an ambient temperature range of 0 °C to 60 °C and carries FM approval for Ta: 0 °C to 70 °C T4 classification, making the 6ES7407-0KA02-0AA0 suitable for demanding industrial environments. With equipment protection class I and integrated protective conductor, the 6ES7407-0KA02-0AA0 ensures safe operation in manufacturing plants, process industries, and heavy industrial facilities where uninterrupted power delivery is essential for maintaining continuous automation processes.
The 6ES7407-0KA02-0AA0 SIEMENS Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Data-Intensive Automation: Powers the high-performance SIMATIC S7-400 platform, which is designed for mid to high-end process engineering and production.
- Critical Infrastructure: Used in food production lines and fluid management systems where reliability is essential.
- Harsh Electrical Environments: Ideal for plants with fluctuating power, as it supports wide-range AC (85–264 V) and DC (88–300 V) networks.
- Data Safety: Functions in systems requiring non-volatile data storage during power failure when paired with backup batteries.
- Slot Requirement: The module occupies 2 slots on the S7-400 rack.
- Software Setup: It is configured using STEP 7 basic software (e.g., within the HW Config editor).
- Battery Monitoring: Users can enable monitoring for one or two optional 3.6 V AA lithium batteries to ensure data backup status is tracked via LEDs (BATT1F/BATT2F).
- Voltage Switching: Features a "Standby" switch that can reduce output voltages to 0 V without disconnecting the mains power.
- Rack Mounting: The module "slips" onto a standard S7-400 rack and is secured with screws.
- Input: Uses a specific AC power plug for both AC and DC network connections.
- Cabling: Requires a cable cross-section of 3x1.5 mm² (stranded wire with ferrules).
- Polarity: For DC operation (88–300 V), reverse polarity of L+ and L- does not affect functionality.
- Integration with CPUs: Once installed, it supplies power directly through the backplane bus to the CPU and signal modules.
- Diagnostics: Integrated LEDs provide immediate feedback on input status and internal faults, simplifying troubleshooting during commissioning.
