SITOP PSU8600 is the first power supply system that is completely embedded in Totally Integrated Automation (TIA) and the TIA Portal.
Reduce downtime with remote monitoring and diagnostics via the integrated webserver or PROFINET. Have an alarm sent if your system encounters a problem like overload or short-circuit.
Save costs by extending the 40 A or 20 A base unit with up to 20 total outputs – no additional wiring required with the system clip link and expansion modules.
Flexibility means less power supplies needed. Adjust each output independently from 5-28 V DC depending on your system requirements.

SITOP PSU8600 is the first power supply system that is completely embedded in Totally Integrated Automation (TIA). Not only does this facilitate especially user-friendly engineering in the TIA Portal, but also extensive evaluation of operating and diagnostics data as well as energy management functions. Not only this, SITOP PSU8600 can also be optimally integrated into existing automation networks via the integrated PROFINET communication.
Thanks to its compact and modular system design, SITOP PSU8600 can be adapted to address the widest range of requirements, and when necessary, can be flexibly expanded. Also when it comes to energy saving, the system has proven to be highly efficient. For instance, thanks to its very high efficiency, by supporting PROFIenergy or by being able to be integrated into energy management systems.
And, when it comes to reliability: 50% extra power for short-term loads, comprehensive monitoring and diagnostic capability, integrated overload monitoring for every output as well as the ability to buffer brief power failures (up to 20 seconds) are just some of the advantages that the SITOP 8600 can offer.
