Siemens 6ES7405-0KA02-0AA0 Power Supply Module

Siemens 6ES7405-0KA02-0AA0 is the PS405 power supply module for the SIMATIC S7-400 PLC family, delivering a 5 V DC output rated at up to 10 A to power the CPU and peripheral logic in a PS405/PS407 power architecture. It accepts a wide DC input of 24, 48, or 60 V and is documented as part of the PS 405/407 family designed for S7-400 systems. With a 5 V DC, 10 A output, this module provides a compact, dedicated 5 V rail for embedded control circuitry within a rack-mounted S7-400 installation. It features mains buffering in accordance with NAMUR recommendations and stores energy for approximately 20 ms during voltage dips, aiding continuity of operation through brief outages. At a 24 V input, the typical input current is about 4 A, aligning with the module’s 24/48/60 V DC operating window. This part number corresponds to a PS405 10 A power supply designed for SIMATIC S7-400 applications and is listed under the PS 405/407 power supply family.
