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.

SITOP PSU8600 base units

SITOP PSU8600 base units

Great performance in a very small space

The high efficiency up to 94% of the basic devices ensures minimum heat loss, which makes very compact designs possible. Up to four outputs monitored for overloads also help save space for circuit-breaking devices. Integrated Ethernet/PROFINET communication opens up new opportunities for diagnostics and the range of applications for your power supply. 

  • 3-phase power supply, nominal output current 20 A or 40 A at 24 V DC 
  • One or four outputs monitored for overload, individually adjustable from 5 V to 28 V
  • Integrated Ethernet/PROFINET interface with two ports
  • Easy configuration in the TIA Portal
  • Extensive diagnostic information and adjustment options with the system in operation
  • Extremely narrow installation width 80/125/100 mm

SITOP CNX8600 expansion modules

SITOP BUF8600 buffer modules

Bridging brief and longer power failures

Buffer modules with electrolytic capacitors, providing buffering for 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 enables industrial PCs to be shut down manually as required. 

  • Base unit capable of being combined with up to two buffer modules to suit requirements
  • Easy to connect using the System Clip Link, a connector for system data and power supply
  • Output voltage: 24 V DC (setting range 5 V to 28 V per output)
  • Max. four expansion modules per base unit le: 4 x 5 A, 4 x 10 A, 8 x 2,5 A, also in optional combination 
  • Narrow installation width: 60 mm for 4 output expansion modules and 100 mm for 8 output expansion modules

UPS8600 uninterruptible power supply

Bridging longer power failures lasting from minutes to hours with full system power

An uninterruptible power supply with appropriate battery modules can be used to protect against longer power dips on the line side and thus to bridge power failures lasting from minutes to hours. These expansion modules make it possible to shut the plant down safely and selectively in the event of a power failure. For most power interruptions, the bridging time is sufficient to allow the plant to continue operating without disruption.

  • UPS8600 module for charge/discharge control with up to five BAT8600 battery modules of the same construction
  • Simple connection of UPS8600 via the System Clip Link, a connector for system data and power supply
  • Smart battery management for optimal battery service life
  • Battery modules BAT8600 with maintenance-free lead-acid or lithium iron phosphate batteries

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.
