Regarding design and functionality, the original power supplies of the SIMATIC integrate optimally into the PLC network. The startup and power reserves of the SITOP power supply units meet the requirements of the respective controllers. In addition, the mounting options of both components are the same. All of this ensures that controller and power supply or peripherals are perfectly matched. In addition to the SIMATIC systems, the SITOP power supply units in SIMATIC design also supply further consumers reliably with 24 Volts.
