Siemens 6ES7407-0RA02-0AA0 is the SIMATIC S7-400 PS407 power supply for the controller rack. It accepts the specified AC or DC input supply. The main backplane output supplies the controller system, with an auxiliary backplane output for the associated loads. Mains buffering bridges a short interruption of the input power. An optional backup battery supports the applicable rack backup arrangement.
The 6ES7407-0RA02-0AA0 provides system power within the S7-400 rack rather than serving as a general-purpose external field supply. The power demand of the installed modules must be assessed against both backplane outputs. Protective-conductor wiring is required for the installation. The selected rack position and input connection must follow the S7-400 installation instructions. Confirm the complete article number and rack power budget before replacing an existing power module.
Supplies the controller and installed modules through the specified S7-400 backplane connections.
Uses the specified stored-energy buffering to bridge brief loss of the mains supply.
Accepts the optional battery arrangement where backup is required by the configured controller system.
It is an S7-400 rack power module. Use its backplane outputs within the specified system arrangement.
The main backplane output does not require a base load.
The backup battery is optional; determine whether the controller installation requires it.
Check the combined demand on both backplane output circuits and the required rack space.
Yes. We can provide actual-item photographs and available inspection information for review.
Confirmed in-stock power supplies are arranged for dispatch immediately after payment is received.
