Siemens PS405/407 Module

Manufacturer: Siemens

The power supply modules are inserted at the far left in the rack (starting from slot 1). Depending on the version, they occupy slots 1 to 3. The modules are enclosed and are cooled via natural convection.

The back-up battery is optional and must be ordered in addition. For power supplies at and above 10 A, two back-up batteries are recommended.

Features Applications Model

Power supplies for SIMATIC S7-400
For conversion of AC or DC line voltages to the 5 V DC and 24 V DC operating voltages required
4 A, 10 A and 20 A output currents

The power supplies supply the S7-400 modules with their 5 V DC and 24 V DC operating voltages via the backplane bus.
Power supplies are available for AC line voltages of 85 to 264 V and for DC voltages of 19.2 to 300 V.
One power supply module is required per rack.
Exception: With interfaces with current transfer, the power supply module in the central controller also supplies all modules in the expansion units.
The load voltage for supplying sensors and actuators must be made available separately.
There are also power supplies to make both the standard system and the H system fail-safe (redundant power supplies).
