Features & Benefits

Three good reasons for SITOP


With SITOP, efficiency starts with the easy selection of devices using the TIA Selection Tool or with design data for all standard CAE systems. The compact and heat-optimized design saves installation space. And in operation, the high efficiency ratings save power, while SITOP PSU8600 records the energy data from all the power management outputs.


SITOP PSU8600 and UPS1600 being completely integrated into Totally Integrated Automation (TIA) and the TIA Portal makes engineering easier and faster, and allows optimized monitoring and end-to-end diagnostics. The SITOP library also makes it possible to incorporate 24 V supply concepts directly into SIMATIC PCS 7.


As they have flexible, wide-range input, outstanding load characteristics and all the relevant certifications, SITOP power supplies guarantee the availability of plants, preventing outages with uninterruptible DC power supplies and preventing overloads and short-circuits in the control circuit using add-on modules. A redundant power supply can also be set up.
