Siemens 6ES7407-0KR02-0AA0 is the SIMATIC S7-400 PS 407 power supply for redundant use. It accepts the specified AC or DC mains supply. The module provides the rack backplane with regulated DC power. Its principal backplane output is rated for 10 A. An optional battery supports the corresponding backup arrangement.
The 6ES7407-0KR02-0AA0 belongs in a compatible S7-400 rack configuration. It supplies controller and module electronics through the backplane. The redundant-use version must be selected to suit the installed rack and power concept. Protective earthing and correct mains connection remain essential during installation. Maintenance planning should include the battery arrangement and the existing power-supply configuration.
Supplies compatible S7-400 modules through the backplane.
Supports the specified redundant power concept in an appropriate S7-400 configuration.
Replaces a matching PS 407 redundant supply after checking rack and mains requirements.
Yes. This order number identifies the redundant-use power supply; verify the associated rack configuration.
The 5 V output requires no base load and the 24 V output is idling-proof.
It is optional; determine the battery requirement from the installed backup arrangement.
Check the mains selection, conductor connection and protective earth against the installed system.
Ask Jim for actual-item photographs, the stated condition and available inspection details. The quoted warranty is 12 months under the agreed terms.
