Siemens 6ES7407-0KR02-0AA0 PS 407 Power Supply | 10A, 120/230V AC, SIMATIC S7-400

Siemens 6ES7407-0KR02-0AA0 power supply specifications. SIMATIC S7-400 PS 407, 10A, 120/230V AC input, 5V/12V/24V DC output.

Product Overview

The Siemens 6ES7407-0KR02-0AA0 is a PS 407 power supply module for the SIMATIC S7-400 programmable logic controller (PLC) system. It converts a wide-range AC input voltage (120/230 V AC) into the regulated DC voltages required by the S7-400 rack, backplane, and inserted modules. This unit provides a rated output current of 10A on the 5V DC bus and includes additional outputs for 24V DC and 12V DC auxiliary supplies.

Key Features

Wide-Range AC Input: Automatic voltage selection (120/230 V AC) for global use
High Output Capacity: 10A on 5V bus supports large S7-400 configurations
Multiple Auxiliary Outputs: Provides 24V DC (1A) and 12V DC (1.5A) for external devices or interface modules
Redundancy Capable: Can be used in redundant power supply configurations (requires additional hardware)
Battery Backup Interface: Supports external battery unit for buffering the internal clock and retentive memory
** Comprehensive Protection: Short-circuit and overvoltage protection
** LED Status Indication: Visual confirmation of correct output voltage
** Hot-Swap Capable: Can be replaced during operation (requires S7-400 rack with appropriate features)

Applications

Primary power supply for SIMATIC S7-400 CPU racks (UR1/UR2/CR2 chassis)
Powering expansion racks (ER1/ER2) via interface modules
Supplying 24V DC auxiliaries for sensors or front connectors
Industrial process control systems requiring high-availability power
Critical infrastructure automation (power, water, transportation)

Important Notes

This power supply occupies two width slots (40 mm each) in a standard S7-400 rack.
For redundant power supply configurations, two PS 407 modules and a redundant coupling module (e.g., 6ES7407-0RA00-0AA0) are required.
A backup battery pack (e.g., 6ES7971-0BA00) must be ordered separately if memory buffering is required.
The auxiliary 24V DC output (1A) is isolated and can be used to power sensors or the S7-400 backplane in isolated mode.
Ensure total 5V current consumption of all modules in the rack does not exceed 10A.
