Siemens 6ES7407-0RA02-0AA0 Power Supply Module

Siemens 6ES7407-0RA02-0AA0 Power Supply Module corresponds to the PS 407 20 A for the SIMATIC S7-400 family, delivering a 5 V DC output up to 20 A (approximately 100 W) to power the S7-400 rack’s processor and I/O modules. It features universal input (UC) of 120/230 V AC, accommodating 50/60 Hz mains for global installations. This module is designed to be integrated into an S7-400 rack alongside CPUs, I/O, and communication modules to provide a dedicated, reliable DC supply for control electronics. Typical applications include industrial automation setups where Siemens S7-400 controllers are used in manufacturing lines, packaging systems, and process control panels that require a compact, robust 5 V DC power source for PLC electronics and peripheral interfaces. The 6ES7407-0RA02-0AA0 designation identifies the PS407 20 A power supply model, and it is commonly listed in Siemens Industry Mall catalogs and distributor pages, reflecting its role as a high-current, 5 V DC supply compatible with S7-400 configurations.
