Siemens's Industry Automation Division has developed two new 3-phase, 24 volt power supplies: the Sitop PSU300P and the Simatic ET200pro PS. These primary switched-mode 8 amp power supplies have the high IP65 degree of protection, and have been designed for distributed use directly in electrical installations. Sitop PSU300P is suitable for universal applications, whereas the Simatic ET200pro PS has been specifically designed for the Simatic ET200pro distributed I/O system, and supplies the electronic and load voltages to its system components.
