The original SIMATIC power supplies harmonize perfectly with the PLC network in terms of their design and functionality. This ensures that controller and power supply are perfectly matched. In addition, the startup and power reserves of the power supply units meet the requirements of the respective controllers. The mounting options of both components are the same. The issued certifications and the permitted temperature range allow the components to be used together in almost all areas. The system test that was performed for each of the SITOP power supply units in SIMATIC design together with the respective SIMATIC controller is particularly noteworthy.

In addition to the following SIMATIC systems, the SITOP power supply units in SIMATIC design also supply further consumers reliably with 24 V.
