SITOP PSU8600 is the first power supply system with full integration in Totally Integrated Automation. This pays off both in engineering in the TIA Portal and in actual 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.
Complex systems place highest demands on their components in terms of efficiency, flexibility and reliability. The innovative SITOP PSU8600 power supply system meets them all – thanks to a unique functionality, diagnostic capability, complete integration into TIA, and modular expandability.
SITOP PSU8600 is the first power supply system that is completely embedded in Totally Integrated Automation (TIA). Not only does this facilitate especially easy, fast and convenient engineering in the TIA Portal, but also extensive evaluation of operating and diagnostics data as well as energy management functions. 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.
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. Because every output can be flexibly set between 5 V and 28 V, there is no need for additional power supply units to run 5 V or 12 V consumers, for instance. And when it comes to energy saving, the system has proven to be highly efficient. Thanks to the very high efficiency rating of the base units (up to 94%), for example, and support for PROFIenergy, individual power supply outputs can be switched off during breaks to save power. And in operation, the system senses the voltage and current data for each individual output, therefore ensuring transparency of the load behavior. This energy data can also be forwarded to higher-level power management systems: for processing and determining potential for energy saving.
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, the buffer operation is signaled for brief line-side voltage dips, and the time that the power actually failed – an ideal indicator to evaluate line quality.
References & applications
From engineering to operation, the powerful, modular SITOP PSU8600 power supply system gives users many advantages for supplying DC power to machines.
At the Siemens plant in Amberg, Siemens AG relies on the modular SITOP PSU8600 power supply system to supply electricity to its state-of-the-art manufacturing facilities.
It monitors all DC outputs for overload or short circuits, and supplies diagnostic and operational information via PROFINET.
For power management, SITOP PSU8600 provides the current and voltage values for all outputs, and switches off all consumers via PROFIenergy as required.
The voltage from every output of the SITOP PSU8600 power supply system can be dynamically adjusted via PROFINET, for example to control the speed of the fans.
The outputs can be switched on and off individually, meaning that loads of up to 20 A can be switched directly without PLC output and without a relay.
The current and voltage of each output can be measured continuously and used for troubleshooting and energy management.
The SITOP PSU8600 power supply system can be fully integrated into the TIA Portal and a TIA Portal project, where it can be configured to communicate with the PLC.
Engineering in the TIA Portal is very convenient, and evaluation of operational and diagnostic data is supported by preassembled function modules for SIMATIC S7 user programs.
Free WinCC faceplates are available for operating and monitoring purposes.
Siemens offers a range of software components to conveniently integrate the SITOP PSU8600 into the TIA environment.
For engineering via the TIA Portal, special functional modules for SIMATIC S7-300, S7-400, S7-1200 and S7-1500 facilitate integration into the STEP 7 user program.
The function modules are available free of charge.
