Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 6ES7405-0KA02-0AA0 is a Siemens SIMATIC S7-400 PS 405 power supply module. It provides dual output voltages (5 V DC for the backplane bus and 24 V DC auxiliary output), ensuring proper system power and I/O support within an S7-400 rack. It accepts a wide DC input range and includes short-circuit protection, overvoltage isolation, and onboard battery backup to maintain system operation during momentary power interruptions. The module is typically used in medium-to-large industrial control cabinets requiring reliable power distribution within S7-400 automation environments.
