Trends & Topics An efficient power supply is a basic requirement for operating any plant, no matter the industry or need. Critical production processes can only be maintained if a constant power supply of the necessary quality is available for the automation system. SITOP has proven its value in the manufacturing environment over many years, and is always setting new standards in terms of integration, efficiency and reliability.

Via PROFINET or OPC UA, the SITOP PSU8600 power supply system integrates the control circuit into the digitalized equipment, making it transparent for the control system.

Automation – the rhythm of our times: For 25 years, SITOP has been bringing productions around the world to life. Join us in celebrating the anniversary of our innovative power supplies. Visit the anniversary page and save 25% with SITOP anniversary packages!

The SITOP devices with PROFINET connection now have an integrated OPC UA server. This allows you to use the power supply system SITOP PSU8600 and integrate the UPS1600 uninterruptible power supply into the cloud – like the MindSphere from Siemens. With this unique transparency, your 24 V supply is "Ready for Industry 4.0". So you can, for example, display status and alarm messages, as well as current energy data from a smart watch – that's digitalization!

The SITOP PSE200U selectivity module distributes the load current across several 24 V DC load circuits and monitors them reliably for overload and short-circuit conditions. The electronics permit brief current peaks caused, for example, by high inrush currents, but isolate 24 V DC load circuits in the event of an extended overload. The SITOP PSE200U continues to supply 24 V DC to the load circuits not affected by an overload – a feature which avoids a possible total system failure.

Whether it’s for industrial or building automation, the fourth generation of the mini power supply units used in their millions around the world for LOGO! 8 modules and other applications offers even more power in an even smaller space. The eleven new LOGO!Power devices for 5 V, 12 V, 15 V and 24 V with standby losses of less than 0.3 W and an efficiency rating of up to 90% offer even higher energy efficiency. The efficient current monitor measures output current at any time without breaking the line and thus the DC power supply. And it can also be wall-mounted in addition to mounting on DIN rails, even in very cold environments with temperatures down to -25°C. All this in a unit that’s 18 mm narrower for every performance class!

Choose, configure and order the right power supply quickly and easily: find out here how you can use the TIA Selection Tool to select the SITOP power supply units you need for your project, under Device Family. Various SITOP product lines are available for selection. A device wizard shortens your path to the suitable power supply – simply enter your technical requirements and the tool shows a tailored display of suitable devices.

Experience the start of a new chapter in the world of standard power supplies with the SITOP PSU6200 all-around power supply. Whether you’re a builder or operator of control panels, machines, or plants, all users benefit from the ingenious functions and features of the new SITOP PSU6200 product line – throughout the entire lifecycle, from planning and engineering to installation and operation.

Three good reasons for SITOP

Efficiency

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.

Integration

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.

Reliability

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.
