Product Overview
The Siemens 6ES7405-0KR02-0AA1 is a PS 405 10 A R series power supply module for the SIMATIC S7-400 automation platform. It converts a wide-range DC input (24/48/60 V) to dual outputs (5 V DC and 24 V DC) for backplane and system power, with integrated redundancy support for enhanced system availability. It incorporates mains buffering according to NAMUR NE 21 and optional AA-battery backup, suitable for industrial applications such as process control systems, redundant PLC configurations, and extended-temperature installations.
