Siemens SITOP Power Supplies



The benchmark in reliability, efficiency and integration

Efficient operation of a machine or plant requires a reliable, constant power supply.

The quality and reliability of the SITOP stabilized power supplies ensure high levels of safety in DC power supply in industrial engineering and building management systems.

Our perfectly coordinated selection of SITOP power supplies is enhanced by a unique range of add-on modules that extensively protect the 24 V power supplies against interference on the primary and secondary side, right up to complete all-round protection.


TOP reliability

You should only have to think once about a good power supply when you are purchasing it – and then never again.

SITOP has proved its reliability more than 10 million times over in almost every supply system in the world. With their wide-range input, excellent load behavior and extensive certification, SITOP power supplies alone ensure the reliability of the power supply.

Depending on requirements, SITOP power supplies can be individually adapted with expansion modules and uninterruptible power supplies (DC UPS). This ensures reliability of the 24 V supply for machines or plants, even in the event of an overload in the output circuit or a power failure on the input side.


TOP efficiency

Production costs are determined more and more by energy costs. Savings in this area generate valuable competitive advantages. SITOP power supplies make an important contribution here. Due to the high degree of efficiency, the primary switched-mode power supplies operate extremely effectively. The power loss across the entire performance range is low – even during no-load operation. Because power supplies are rarely operated at full load, there is outstanding potential for savings here.

SITOP also supports the entire process chain of the customer efficiently. It offers easy product selection using the SITOP Selection Tool, for example, and extensive additional information such as 3D data, circuit diagram macros, certification and individually-configurable product documentation. Every SITOP solution can therefore be planned and ordered, designed, configured and operated in an extremely efficient manner.


TOP integration

The better power supplies are integrated in their industrial environment, the higher their productivity. SITOP is optimally tailored to automation systems such as SIMATIC, SINUMERIK and SIMOTION.

In addition, the PSU8600 power supply system and the UPS1600 uninterruptible power supply are completely integrated in TIA. Convenient engineering in the TIA Portal supports, for example, easy network integration in PROFINET or comprehensive diagnostics.

SIMATIC S7 function blocks support easy integration in STEP 7 user programs, and ready-to-use WinCC faceplates are available for operator control and monitoring.
