SIEMENS SIMATIC S7-1500 – 6ES7505-0KA00-0AB0


  • System power supplies for SIMATIC S7-1500
  • For conversion of AC or DC line voltages to the operating voltages required for the internal electronics
  • 25 or 60 W output power
  • Can be used for S7-1500 or ET 200MP
  • Engineering and configuration via STEP 7 V12 and higher (PS 60W 24/48/60V DC HF: from STEP 7 V14 SP1)
  • In addition with PS 60W 24/48/60V DC HF: Retentive storage of CPU work memory (data) for all S7-1500 CPUs


Power supplies (PS) supply the internal electronics of the S7-1500 modules with power via the backplane bus. They are required, for example, if the power supplied by the CPU or the interface modules to the backplane bus is not sufficient to supply all connected modules, or if more than one power segment in the S7-1500 configuration or in distributed configuration in ET 200MP should be implemented.

In addition, the PS 60W 24/48/60V DC HF allows all S7-1500 CPUs to retentively store their entire work memory (data) thanks to an appropriate power buffer.


Power supplies are screwed directly to the S7-1500 mounting rail and are connected with the upstream or downstream module via a U connector. PS 60W 24/48/60V DC HF can only be connected next to the CPU/IM on the left-hand side.

The front of the power supply contains:

  • Diagnostics LEDs to indicate status and errors:
    Error (Error), operation (RUN), maintenance (MAINT)

The power supplies also come with the following:

  • On-off switch
  • Power supply terminals



  • Rated input voltage dependent on the type of module
  • Output power dependent on the type of module
  • Mains buffering
  • Galvanic isolation from the bus

The following functions are supported by the power supply modules:

  • Firmware update
  • Identification and maintenance data I&M0 to I&M3
  • Reconfiguration in RUN
  • Diagnostics alarms
  • Diagnostic interrupts


SIMATIC S7-1500, System power supply PS 25W 24 V DC, supplies the backplane bus of the S7-1500 with operating voltage
