SITOP modular,
PSU8600 power supply system
Introduction
■
Overview
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. Voltage and current
response thresholds can be set individually for each output of
the power supply system, and selective monitoring of each
output for overload results in fast fault location. 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 diagnostic and maintenance information is
available via PROFINET. It can be evaluated directly in 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 from individual outputs, the specific
activation and deactivation of outputs via PROFIenergy, to direct
integration in power management systems.
■
Benefits
•
Reduced space requirement and costs due to multiple
integrated outputs with selective monitoring
•
Individually configurable outputs (no need for additional
power supply for 5 V, 12 V or 15 V)
•
Compensation for power losses can be set separately for
each output
•
Narrow width without lateral installation clearances
•
Low temperature rise in the control cabinet due to very high
efficiency
•
If required, extra units from the modular system (more outputs,
buffer module) can be added without wiring effort
•
Reliable operation due to bridging of short-term power failures
•
Two integrated Ethernet/PROFINET ports (no external switch
required)
•
Complete integration in TIA requires less time and reduces
costs during configuration (TIA Portal) and in operation
•
SIMATIC S7 function blocks for easy integration in STEP 7 user
programs
•
Fast integration in operator control and monitoring with WinCC
faceplates
•
Preventive maintenance reduces downtimes
•
Energy savings during breaks through targeted switching of
outputs
•
Easy integration in energy management systems
(PROFIenergy protocol)

Application
The SITOP PSU8600 power supply system is used as the central
DC power supply of larger plants or machines with networked
automation systems. The PSU8600 can be directly integrated
into the LAN infrastructure by means of the two integrated
PROFINET ports.
An extremely high level of reliability is achieved for the
DC voltage supply by monitoring the individual DC branches for
overload and bridging short-term power failures (brownouts).
Complete transparency and fast fault localization are achieved
by providing comprehensive diagnostic and maintenance
information (e.g. load states of the outputs, phase/network
failure, overtemperature) via PROFINET.
Energy-optimized operation is supported by measuring the
current power and voltage values of the individual outputs as
well as the individual activation and deactivation of the
DC outputs via PROFIenergy during break times.
