Parallel connection to increase power rating
To increase the power rating, SITOP PSU8200 power supplies of the same type can be
directly connected in parallel.
The following must be observed:
● The cables connected to each power supply at terminals "+" and "-" must have identical
lengths and the same cable cross-sections (or the same impedance) up to a common
external connection point (terminal strip) if possible.
● The power supplies connected in parallel must be switched on simultaneously with a
common switch in the line feeder cable (e.g. with the main switch available in control
cabinets).
● The output voltages measured in no-load operation for the power supplies that are not yet
connected in parallel should not deviate more than a maximum of 50 mV. This usually
corresponds to the factory setting. If the output voltage is changed, you should connect
the "-" terminals and then, in no-load operation, measure the voltage difference between
the "+" terminals that have not yet been connected. The voltage difference should not
exceed 50 mV.
● Switch change-over switch "A" (see Figure 2-5 Selector switch (example: 6EP3333-
8SB00-0AY0) (Page 13)) to "Parallel operation".

NOTICE
Protective circuit for the parallel connection of more than two power supplies
9.1 Parallel connection to increase power rating
For connection of more than two power supplies in parallel, additional measures must be
taken to prevent high backward feeding currents in the event of a secondary device
fault. For this purpose, a suitable protective circuit (e.g. decoupling diode
or DC-conform circuit-breaker) must be installed between each "+" terminal of the power
supply and the common connection point.

Parallel connection for redundancy
Note
For a high reliability of the supply, it
power supplies are fused separately on the line
power supply networks.
9.2 Parallel connection for redundancy
Connecting several SITOP PSU8200 power supplies in parallel for redundancy purposes is
required if especially high demands are placed regarding the availability of a reliable 24 V
power supply.
Using the SITOP PSE202Uredundancy module, two 24 V power supplies of the same type
up to 20 A can be decoupled (Figure 9-2 Redundant configuration with two power supplies
and SITOP PSE202U redundancy module (Page 49)). When one of the devices fails, then
the other automatically takes over the power supply. If one of the power supplies fails, then
this is signaled using an LED on the redundancy module as well as an isolated relay contact.
When dimensioning the system, it must be ensured that n+1 redundant connected power
supplies can handle the total power requirement of the remaining n power supplies.
is recommended that the redundant switched

Series connection for increased voltage
WARNING
SELV is not guaranteed in the case of a fault
9.3 Series connection for increased voltage
To achieve an output voltage of 48 V DC, two 24 V SITOP PSU8200 power supplies of the
same type can be connected in series. In this case, connect the "-" terminal of the first power
supply to the "+" terminal of the second power supply. The "+" terminal of the first power
supply and the "-" terminal of the second power supply are routed to the load.
Depending on the grounding point of the secondary output voltages, voltages of +48 V,
±24 V or -48 V can be realized.
In the case of an asymmetric load distribution, it is not possible to guarantee correct
functionality.
When connecting two power supplies in series, the continuous, permissible SELV voltage
of a maximum of 60 VDC according to EN 60950 cannot be guaranteed in the case of a
fault.

Overload protection in the 24 V output circuit
9.4 Overload protection in the 24 V output circuit
If an overload occurs, the electronic current limiting function limits the SITOP PSU8200
output current to a maximum value (see section Technical data (Page 31)). The output
cables are protected against a thermal overload if they are dimensioned corresponding to
the maximum rms output current, or protected using additional components (for example,
miniature circuit breaker, fuses).
However, a load circuit that fails as a result of overload, for instance, should frequently be
reliably and quickly identified and specifically switched off before the power supply goes into
current-limiting mode (in current-limiting mode, the supply voltage would also be reduced for
all of the remaining 24 V loads).
The SITOP PSE200U selectivity module with 4 channels (versions with adjustable output
current range for each channel from 0.5-3 A and 3-10 A) is available for this purpose; this
monitors the 24 V branches for overloading and short-circuiting (Figure 9-4 Electronic
protection of 24 V consumers with the SITOP PSE200U selectivity module (Page 51)). Brief
current peaks, e.g. as a result of a high inrush current, are permitted, and branches with a
longer overload are switched into a no-current condition. This is also ensured for cables in a
high-ohmic condition and for short-circuits that slowly develop over time.
When a channel fails, the fault is signaled using a group signal contact or as a single
channel signal, and the branch of the module involved is displayed using an LED.
For versions with single-channel signaling, function blocks for evaluation purposes are
available at no charge for SIMATIC S7-1200/1500/300/400, for STEP 7 and TIA Portal as
well as for SIMOTION CPUs and SIMOTION SCOUT.

Protection against short-time voltage dips
9.5 Protection against short-time voltage dips
In the case of a drop in the line-side supply voltage, the SITOP PSU8200 power supply can
still maintain the output voltage for a short time in the millisecond range (see section
Technical data (Page 31)).
For line supplies that manifest frequent brief voltage dips, in order to increase the power
supply reliability, it may make sense to increase the line buffering time in the device using an
additional SITOP PSE201U buffer module.
The SITOP PSE201U buffer module, based on electrolytic capacitors, is connected in
parallel to the 24 V power supply output (Figure 9-5 Buffering brief power failures using the
SITOP PSE201U buffer module (Page 52)). The buffer time is 200 ms at 40 A up to 1.6 s for
a load current of 5 A. This time can be increased a multiple number of times by connecting
buffer modules in parallel; the maximum buffer time is 10 s.
You can find additional information at:

Protecting against longer power failures
9.6 Protecting against longer power failures
Sudden and longer failures of the line supply voltage can result in undefined states and
significant danger as a result of the associated failure of the plant or system control. The
SITOP power supply product portfolio includes various DC-UPS solutions to prevent the
failure of the 24 V power supply voltage.
Power supply failures up into the minutes range can be buffered using the maintenance-free

Using DC UPS SITOP UPS1600 and SITOP UPS100 battery modules, buffer times in the
range of hours can be implemented. Intelligent battery management using Energy Storage
Link automatically detects the UPS1100 energy storage device, and ensures optimum
temperature-controlled charging and continuous monitoring. The UPS1600 can be flexibly
integrated into the widest range of automation applications with its digital inputs/outputs as
well as optional USB interface or Ethernet/PROFINET port.

sensor measured values and position values
For open, PC-based automation systems, configuration and monitoring is realized using the
SITOP UPS Manager PC software, which is available at no charge. This allows PC
responses to the operating states of the DC UPS to be freely selected – and offers
comprehensive diagnostic functions.
For TIA-based automation systems, the UPS1600 is engineered using the TIA Portal.
Special function blocks for SIMATIC S7-300/400/1200 and S7-1500 – available at no charge
– make it easy to integrate operating and diagnostics information into STEP 7 user
programs. Preconfigured UPS faceplates for WinCC visualization can be downloaded at no
charge.
