SITOP
SITOP modular, PSU8600 power supply system
As a unique power supply system with complete integration in Totally Integrated Automation (TIA),
SITOP PSU8600 sets new standards in industrial power supplies.
The benefits of this integration are not only apparent during engineering in TIA Portal but also result in reliable
operation.
The voltage and current response threshold can be individually set for each output of the power supply system
and the selective monitoring of each output for overload allows quick localization of faults.
Depending on requirements additional modules from the modular system, such as are used for buffering short
power failures, can be added without wiring overhead.
Comprehensive diagnostics and maintenance information is available via PROFINET and can be evaluated
directly in the SIMATIC S7 and visualized in SIMATIC WinCC.
Optimal support is also provided for energy management of plant or machines:
From the acquisition of energy data of the individual outputs and individual switching on/off of the outputs via
PROFIenergy to direct integration into energy management systems.
Essential product features
• 3-phase wide range input 400 to 500 V 3 AC for global use
• Versions with a parameterizable output with a maximum of 20 A or 40 A and selective monitoring
• Versions with four integrated, individually parameterizable outputs with a maximum of 5 A or 10 A and selective
monitoring
• Integrated Ethernet/PROFINET interface (2 ports)
• Extremely slim design with very high efficiency of up to 94 %
• Extra power with 1.5 times the rated current (5 s/min) for brief operational overloads
• Easy configuration in the TIA Portal
• Individual expansion options from the modular system
(CNX8600 expansion modules, BUF8600 buffer modules) without wiring overhead
SITOP expansion modules
Expansion modules for increasing system availability
A power supply unit on its own cannot guarantee fault-free 24 V supply. Power failures, extreme variations in the
mains voltage, or a faulty load can bring plant operation to a standstill and cause high costs.
The expansion modules offer extensive protection against malfunctions on the primary and secondary circuits,
right through to complete all-round protection.
