SITOP modular,
PSU8600 power supply system
Introduction
■
Design
Basic devices
•
SITOP PSU8600, 3-phase power supply, 24 V DC/20 A/4x 5 A
with four outputs (max. 5 A per output) and two Ethernet/
PROFINET ports
•
SITOP PSU8600, 3-phase power supply, 24 V DC/20 A
with one output and two Ethernet/PROFINET ports
•
SITOP PSU8600, 3-phase power supply, 24 V DC/40 A/
4x 10 A with four outputs (max. 10 A per output) and two
Ethernet/PROFINET ports
•
SITOP PSU8600, 3-phase power supply, 24 V DC/40 A
with one output and two Ethernet/PROFINET ports
Modular system, consisting of:
•
SITOP CNX8600 4x 5 A
(expansion module with 4 outputs at 5 A each)
•
SITOP CNX8600 4x 10 A
(expansion module with 4 outputs at 10 A each)
•
SITOP BUF8600 100 ms/40 A
(buffer module with 100 ms at 40 A)
•
SITOP BUF8600 300 ms/40 A
(buffer module with 300 ms at 40 A)
•
SITOP BUF8600 4 s/40 A
(buffer module with 4 s at 40 A)
•
SITOP BUF8600 10 s/40 A
(buffer module with 10 s at 40 A)
You can connect up to four CNX8600 expansion modules as well
as up to two BUF8600 buffer modules to the PSU8600 basic de-
vice. Connection takes place on top of the modules without any
wiring by means of the System Clip Link, a connecting plug for
system data and power supply. The order of the up to six possi-
ble add-on modules is random so that an existing configuration
does not have to be altered if a module is added later.

Function
Supply of connected loads
An individual supply voltage can be set at each output of the
power supply system. This means you can supply loads with
different rated voltages simultaneously with only one device.
Plus the voltage drop caused by the different cable lengths can
be compensated individually, which means each load can be
supplied with the optimum voltage.
Monitoring of the outputs for overload
Each output of the power supply system is individually moni-
tored for overload. If the load current exceeds the set response
threshold, the output is shut down according to specified
time-current characteristics. All other outputs continue to be
supplied reaction-free.
Enabling and disabling the outputs
Each output can be manually enabled or disabled directly on the
device (e.g. for commissioning or service) and an overload
tripping can be reset. Outputs disabled due to overload can also
be reset remotely using a remote signal signal (24 V input).
In addition, program-controlled enabling and disabling of the
outputs is possible using the integrated Ethernet/
PROFINET interface. This also means you can disable individual
outputs by means of PROFIenergy during breaks to save energy.

Communication
Comprehensive diagnostic information can be queried and
processed via the integrated Ethernet/PROFINET interface
during operation for both the device status as well as the status
of the individual outputs. This results in complete transparency,
minimal downtimes and quick fault location. The integrated web
server also permits remote monitoring of the power supply
system.
Buffering
In case of short-term power failure, the buffer module supplies
the load current for supplying the outputs by means of its energy
storage units Maintenance-free electrolytic capacitors or dou-
ble-layer capacitors are used as energy-storage units.
■
Integration
Software for TIA-based automation systems
Different software components are available to facilitate easy
integration of the SITOP PSU8600 in the TIA environment.
Engineering is simple via the TIA Portal. Special function blocks
for SIMATIC S7-300, S7-400, S7-1200 and S7-1500 also support
integration in the STEP 7 user program.
The comprehensive operating and diagnostic data of the power
supply system can be visualized using ready-to-use PSU8600
faceplates for WinCC.
TIA Portal
