Product Overview
The 6ES7405-0KR02-0AA0 is a Siemens SIMATIC S7-400 PS405 10 A R redundant power supply module. It provides dual-output DC power (5 V and 24 V) to the S7-400 backplane, with selectable input ranges of 24, 48, or 60 V DC. Designed for use in redundant power architectures, it delivers uninterruptible operation in medium- to large-scale industrial control systems such as manufacturing lines, process plants, and infrastructure automation.
