Siemens SIPLUS SITOP power supplies

SIPLUS SITOP power supplies

SIPLUS SITOP power supply units are globally recognized for their high reliability and for their coping with critical network conditions. Our full range of switched-mode power supply units provides a controlled 24 V DC power supply and other input voltages. Our unique spectrum of DC UPS and add-on modules extends our power supply range to protect the 24 V supply against mains problems and problems on the DC side. SITOP is also top-notch when it comes to efficiency, thanks to an efficiency rating of up to 95%, for example, tools to make product selection and ordering quick and easy, and comprehensive support for your design processes. And in terms of integration, complete integration in Totally Integrated Automation and the TIA Portal via PROFINET gives you unique opportunities for engineering and diagnostics.

Top integration. Top efficiency. Top reliability. SITOP

SITOP compact – the slim power supply for control boxes
SITOP compact are slim and highly efficient power supplies for the lower power range. They are ideally suited for decentralized applications.
LOGO!Power – the flat power supply for distribution boards
The miniature power supply units in the LOGO! 8 module design take up very little space but offer lots of power. They can be deployed in a large number of applications in the lower power range.
SITOP lite – the low-cost basic power supply
SITOP lite is the power supply series for basic requirements in the industrial environment, offering all the important functions at a low cost – without compromising quality and reliability.
SITOP smart – the powerful standard power supply
SITOP smart is the optimal power supply for many 24 V and 12 V applications, featuring compact design, powerful performance, and low price.
SITOP modular – the technology power supply for demanding solutions
SITOP modular provides maximum functionality and reliability for use in complex plants and machines.

SITOP PSU8600 – the modular power supply system with integrated PROFINET communication
The modular SITOP PSU8600 power supply system is completely integrated into Totally Integrated Automation and is integrated directly into networked machines and systems via its Ethernet/PROFINET interface.
SITOP in SIMATIC design – the optimal power supply for SIMATIC S7 and more
The design and functionality of the original SIMATIC power supplies merge into the PLC network. Of course, they also supply other loads reliably with 24 V.
Special designs and uses – power supplies for specific tasks
Restricted installation conditions, harsh environmental conditions, or special input and output voltages: these standard power supplies meet even exceptional requirements.

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 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 with features such as the 24 V load view in the TIA Selection Tool, the SITOP Selection Tool, 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.
