SITOP PSU8600 – the unique power supply system with PROFINET

An integrated power supply is the future. Or is already reality today.
SITOP PSU8600 is the first power supply system with a complete integration in Totally Integrated Automation. This not only pays off in engineering in the TIA Portal or in manufacturer-independent communication systems, but also in operation. For example, voltage and current can be individually adjusted for each output, and the integrated overload protection enables each output to be monitored. Other modules from the system toolbox can be added to suit requirements with no wiring overhead, for example to buffer power failures. Comprehensive diagnostic and maintenance information is available via PROFINET. SITOP provides the best possible support for power management for plants or machines, from recording power data from individual outputs to switching outputs on and off via PROFIenergy. In this way, the SITOP PSU8600 is setting new standards in plant reliability and efficiency.
Integrated power supply and system
Complex facilities require high conditions on the efficiency, flexibility and reliability of their components. The innovative SITOP PSU8600 power supply system satisfies them all – thanks to ist unique functionality, diagnostic capability, full integration in TIA, open communication networks and modular expandibility.Top integration – with complete system integration
With its entire integration in Totally Integrated Automation (TIA), SITOP PSU8600 is the first power supply system to offer notably simple, fast and convenient engineering in the TIA Portal, as well as an extensive evaluation of operating and diagnostic data and energy management functions. Furthermore, the same functions can be realized with open communication either via OPC UA or with the SITOP Manager. SITOP PSU8600 with its Industrial Ethernet/PROFINET switch functionality, with two ports on the base units, can be perfectly incorporated into existing automation networks in both in-line and ring structures. The integrated Web server also allows power supply monitoring or diagnosis to be performed remotely.
Top efficiency – from engineering through to operation
SITOP PSU8600 is the first power supply system that is completely embedded in the digital world of automation. On the one hand, complete integration into Totally Integrated Automation (TIA) not only permits especially easy, fast, and convenient engineeringTotally Integrated Automation (TIA). Not only does this facilitate especially easy, fast and convenient engineering in the TIA Portal, but also allows extensive evaluation of operating and diagnostics data as well as energy management functions. On the other hand, the same functions can be implemented for open communication with OPC UA.

The integrated Web server also allows power supply monitoring or diagnosis to be performed remotely.
Top reliability – thanks to selectivity and monitoring
SITOP PSU8600 offers the optimum basis to identify and eliminate faults at an early stage, initiate preventive maintenance and avoid plant downtimes. This includes monitoring all of the outputs – and selectively switching them off when a fault develops, for instance. As a consequence, a short circuit or an overload at an individual load does not mean that the complete plant or system shuts down. 50% extra power for short-term loads as well as the ability to buffer brief power failures up to 20 seconds at a full 40 A load are further advantages that the SITOP PSU8600 can offer. Additionally, buffer and battery operation are signaled for line-side voltage dips, and the time that the power actually failed – an ideal indicator to evaluate line quality.
SITOP PSU8600 offers a lot – in a highly compact design. This not only includes 50% extra power for brief overloads, but also integrated overload monitoring for every output. As a result, even the base units enable the use of additional circuit-breakers, and with installed widths of just 80-125 mm, they save a great deal of space in the control panel. The high efficiency rating up to 94% ensures minimum heat loss.
With its modular design, SITOP PSU8600 can be flexibly adapted to address the particular application. The System Clip Link is a connector for system data and power supply. This allows basic devices to be expanded using expansion modules, buffer modules, and uninterruptible power supplies without requiring any wiring. A maximum of six modules can be used in any sequence. Up to 20 outlets can now be selectively monitored by connecting up to four expansion modules. To protect against short-term voltage dips at the network end, up to two SITOP BUF8600 buffer modules with electrolytic capacitors for up to 600 ms at full load (40 A) can be added – and to protect against longer outages, up to two SITOP BUF8600 buffer modules with double-layer capacitors for up to 20 s at 40 A. For bridging power failures lasting from minutes to hours, up to two UPS8600 uninterruptible power supplies can be mounted side by side and each can be expanded with a maximum of five battery modules of the same construction. Battery modules using lithium iron phosphate (LiFePO4) technology ensure an especially long service life with an average mains power failure bridging time of 14 minutes at full load (960 W). Lead batteries (Pb) have a “normal” service life with an average buffering time of 10 minutes at full load (960 W).
For integration into manufacturer-independent networks, communication via the OPC UA server functionality can be selected. In this case as well, all program-controlled parametrization and diagnostics options are available.
With SITOP PSU8600, a power supply can be completely integrated in open, networked automation applications and in the TIA Portal for the first time. Engineering in the TIA Portal is particularly easy, fast and convenient - e.g. Setting up the network connection via PROFINET as well as selecting and parameterizing the power supply, including switching on and off of individual outputs. Prefabricated function blocks for SIMATIC S7 user programs support the operation and diagnostic data analysis - and free WinCC faceplates the setup for operatingand monitoring. For the integration into manufacturer-independent networks, the communication can be selected via OPC UA or the SITOP Manager. All program-controlled parameterization and diagnostics options are also available via these paths.
