Overview of SITOP

Integrated power supply and system

Complex facilities place high demands on the efficiency, flexibility, and reliability of their components. The innovative SITOP PSU8600 power supply system satisfies them all – thanks to its unique functionality, diagnostic capability, full integration in TIA, open communication networks, and modular expandability.

The SITOP power supply system includes the basic SITOP PSU8600 units, the SITOP CNX8600 expansion units, the SITOP BUF8600 buffer modules, and the SITOP UPS8600 UPS module with BAT8600 battery modules. 

 

The modular system toolbox can be fully integrated into automation landscapes and the Totally Integrated Automation Portal (TIA Portal). Communication via the Ethernet/PROFINET or OPC UA interface is easy. In addition to its operating and monitoring processes, you can use the SITOP Manager to set parameters. Use the integrated web server for remote access.

Overview of all system components

SITOP PSU8600 base units

(1- and 3-phase)

Strong performance in the smallest space

The high efficiency of the base units (up to 94 percent) ensures minimum heat loss, which means very compact structures can be used. Up to four outputs monitored for overload also save space for circuit-breaking devices. Integrated Ethernet/PROFINET communication creates new opportunities for diagnostics and broadens the range of applications for your power supply.

SITOP CNX8600 expansion modules

More outputs for more flexibility

The expansion modules can be used to expand the base units with up to 32 additional, selectively monitored outputs. Connect them to the top of the modules using the System Clip Link, a connector for system data and power supply, with no wiring overheads.

SITOP BUF8600 buffer modules

Bridging brief and longer power failures

ZBuffer modules with electrolytic capacitors that can buffer up to 600 ms at a load current of 40 A can be used to protect against brief power dips on the line side (brownouts). The versions with double-layer capacitors (UltraCaps) buffer against longer outages, up to 20 s at 40 A. Because the buffer time is longer for lower buffer currents, this allows devices like industrial PCs to be shut down manually as required.

SITOP UPS8600 UPS module with BAT8600 battery modules

Bridging longer power failures in the minute to hour range at full system power

A UPS module with the appropriate battery modules can be used to protect against longer power dips on the line side. This enables bridging of power failures in the minute to hour range. In the event of a power failure, these add-on modules let you power the plant down safely while maintaining control. For most interruptions to the power supply, the bridging time is long enough to enable the plant to continue running without disruption.

PSU8600 and SIMATIC PCS 7: Better Together

Did you know you can virtually eliminate plant downtime and its associated costs by integrating your power supply system and distributed control system?

The Siemens SITOP PSU8600 power supply system has prebuilt engineering (Advanced Process Library) and simulation (SIMIT) libraries for direct integration with the SIMATIC PCS 7 DCS, enabling consistent transparency of the 24-volt DC power supply and immediate detection of critical plant states. The intuitive interface visualizes diagnostic information in a simple, user-friendly way, making it clear which actions should be taken to ensure uninterrupted system uptime.

Links and information

SITOP Manager, TIA Selection Tool, and more information

SITOP Manager: The tool for commissioning, engineering, and monitoring

With the SITOP Manager software, all power supply systems in a network can be parameterized and diagnosed using a PC with the Windows 7 or 10 or Industrial OS operating system. This is ideal especially if the system configuration and programming aren’t performed in the TIA Portal or SIMATIC Step 7.

 

Communication between the SITOP Manager and the power supply takes place via OPC UA, the open, manufacturer vendor-independent, and Ethernet-based communication standard. Thanks to the Web browser-based user interface, the application can also run on mobile devices and automatically adapts to the display size.

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.
