Potentiometer
The potentiometer ④ on the front of the device is used to adjust the output voltage. The
output voltage is set to 12 V, 24 V or 48 V in the factory, and can be adjusted in the range
12 ... 14 V, 24 ... 28.8 V or 42 ... 56 V; for example, to compensate voltage drops across long
supply lines to the connected load.
Figure 2-4 Potentiometer (example 6EP1456-3BA00 / 6EP1437-3BA20)
NOTICE
Thermal overload possible
When adjusting the output voltage to >24 V (>48 V), the output current must be derated by
4 %/V or the permissible ambient temperature must be taken into account with 3 K/V
(applies to PSU300M devices).
Note
It is only permissible to use an insulated screwdriver when actuating the potentiometer.
For notes on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data

The two switches A and B are used to influence the output characteristic curve:
Switch

OFF
A
influences the output
characteristic
in the load range
Parallel operation:
'Soft' characteristic curve (see, e.g. Figure 6-8
6EP1436-3BA10 parallel operation output char-
acteristic curve (Page 46)) for the parallel oper-
ation of two or more devices: The output
voltage falls with increasing output current
(namely, also for the overcurrent pulse!).
This means that for full output current the high-
est output voltage can normally no longer be
attained.
Single operation:
Delivery state
'Hard' characteristic curve (see, e.g. Figure 6-3
6EP1436-3BA10 single operation output char-
acteristic curve (Page 44)) for normal operation
(single operation): The output voltage is inde-
pendent of the output current.
B
influences the output
characteristic
in the overload range
Latching shutdown:
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage (see, e.g. Figure 6-13
6EP1436-3BA10 latching shutdown output
characteristic curve (Page 48)). If the output
voltage falls below (10 V), (20 V), (40 V), the
device shuts down latching, the red LED lights.
This limit voltage of (10 V), (20 V), (40 V) is
independent of the set output voltage. The
'Short-time overload current' feature is not
available in this operating mode. In order to
also be able to charge large capacitances in
this operating mode at the output, non-latching
shutdown is performed during the first ten sec-
onds after power on. During these first 10 s, the
device responds for overload as if the switch is
OFF.
Constant current:
Delivery state
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage. The yellow LED lights if the
output voltage falls below
(10 V), (20 V), (40 V).
Delivery state: A-OFF; B-OFF

WARNING
Hazard due to electric shock
Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again. If this instruction is
not observed, touching live parts can result in death or serious injury.
5.1
Line-side connection
The SITOP PSU300M/300B power supply is designed for connection to a 3-phase AC line
supply (TN or TT system according to VDE 0100 T 300/IEC 364-3) with a rated voltage of
3-phase 400-500 V AC, 50/-60 Hz, IT system with rated voltages 3-phase 400-480 V AC.
Figure 5-1 Line connection (example: 6EP1456-3BA00)
The line supply is connected using terminals L1, L2, L3 and PE (see Figure 5-1 Line
connection (example: 6EP1456-3BA00) (Page 35)), and must be implemented according to
IEC 60364 and EN 50178 . A protective device (miniature circuit breaker or circuit breaker)
and a disconnection unit for the power supply must be provided. A ground-fault circuit
interrupter is not permissible against indirect contact as the only protective measure. This
applies for the complete line supply protected by the ground-fault circuit interrupter.

5.2
Output-side connection
At its output, the SITOP PSU300M/300B power supply provides an isolated (= non-
grounded) SELV output voltage (Safety Extra Low Voltage). The output of the power supply
is no-load, overload, and short-circuit proof. If an overload occurs, the electronic current
limiting function limits the output current to a maximum value (see Section Technical data
(Page 39)).
Figure 5-2 Output connection (example 6EP1456-3BA00 / 6EP1437-3BA20)
The output voltage is connected via the + and - terminals at the output of the power supply
(see Figure 5-2 Output connection (example 6EP1456-3BA00 / 6EP1437-3BA20)
(Page 37)). Ensure that the output cables are dimensioned correctly for the maximum output
current rms value and fused accordingly.
Note
If the safety concept of the plant or system specifies that the DC output circuit should be
grounded (PELV), then it is permissible that the output voltage of the SITOP power s
upply is
grounded. In this case, ideally, the grounding at the output should be directly connected from
terminal "
-" of the power supply to a suitable connection point of the protective conductor
system (PE) of the plant or system.

9.1
Parallel connection to increase power rating
To increase the power rating, SITOP PSU300M/300B 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.
● Place selector switch A at "ON" (see Section Change-over switch (Page 15))

NOTICE
Protective circuit for the parallel connection of more than two power supplies
When connecting 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.

SITOP PSU300M/300B
Manual, 11.2014, C98130-A7574-A2-2-7629 67
9.2
Parallel connection for redundancy
Connecting several SITOP PSU300M/300B 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 PSE202U redundancy 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 one SITOP PSE202U redundancy module (Page 67)). 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.
For higher output current, each power supply must be connected to a redundancy module
(Figure 9-3 Redundant configuration with two power supplies and two SITOP PSE202U
redundancy modules (Page 68)).
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.
Note
For a high reliability of the supply, it is recommended that the redundant switched power
supplies are fused separately on the li
ne-side and, if possible, be connected to different
power supply networks.

Series connection for increased voltage
To achieve an output voltage of 48 V DC, two 24 V SITOP PSU300M/300M 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.
WARNING
SELV is not guaranteed in the case of a fault
When connecting two power supplies in series, the continuous, permissible SELV voltage
of a maximum of 60 V DC according to EN 60950 cannot be guaranteed in the case of a
fault.

If an overload occurs, the electronic current limiting function limits the
SITOP PSU300M/300B output current to a maximum value (see Section Technical data
(Page 39)). 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 outputs (versions with adjustable output
current range for each output from 0.5 ... 3 A and 3 ... 10 A) is available; this monitors the
24 V branches for overload and short circuits (Figure 9-5 Selectivity module (Page 70)). 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 an output 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 variants with single channel signaling, function blocks for evaluation purposes are
available for SIMATIC S7-1200/1500/300/400, for STEP 7 Classic and TIA Portal at no
charge.

Protection against short-time voltage dips
For a drop in the line-side supply voltage, the SITOP PSU300M/300B power supply still
maintains the output voltage for a short time in the millisecond range (see Chapter Technical
data (Page 39)).
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 9-6 Buffer module (Page 71)). 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.

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
SITOP UPS500 DC-UPS modules based on capacitors (Figure 9-7 24 V buffering to allow
the saving of process data and controlled shutdown of PCs (Page 72)).
Figure 9-7 24 V buffering to allow the saving of process data and controlled shutdown of PCs
Using the free-of-charge SITOP DC-UPS software tool, DC-UPS systems can be simply
integrated into PC-based automation solutions. This supports further processing of the status
signals and safely running down the PC.

Using DC UPS SITOP UPS1600 and SITOP UPS1100 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.

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

Battery charging with SITOP PSU300B
The SITOP PSU300B power supplies are optimized for charging lead accumulators. For a U-
I characteristic curve set to parallel operation (DIP switch "A" at "ON", see Section Figure 2-6
Selector switch (example 6EP1456-3BA00 / 6EP1437-3BA20) (Page 15)), the battery to be
charged is charged with a constant current until approximately 95% of the set SITOP output
voltage is reached (set using a potentiometer, see Section Figure 2-4 Potentiometer
(example 6EP1456-3BA00 / 6EP1437-3BA20) (Page 11)). The charging current then
decreases continuously from 1.2 × rated current at 95% of the set voltage to approx. 0 A or
the self-discharging current of the accumulator at 100% of the set output voltage, i.e. the
resistance characteristic curve in this range (see Figure 6-10 6EP1424-3BA00 parallel
operation output characteristic curve (Page 46), Figure 6-11 6EP1436-3BA20 parallel
operation output characteristic curve (Page 47), Figure 6-12 6EP1437-3BA20 parallel
operation output characteristic curve (Page 47)).
Note
The value recommended by the battery manufacturer (dependent on the accumulator
temperature) must be set as end
-of-charge voltage. A lead accumulator temperature of +20°
to 30° C is ideal; in this
case, the recommended end-of-charge voltage is normally approx.
13.5 or 27
V.
Note
As protection against back e.m.f. and as polarity reversal protection, we recommend that a
suitable diode for at least 1.2 × rated current of the power supply with a
t least 40 V blocking
voltage is connected in series to the "+" output (connect the anode with "+" output of the
SITOP PSU300B and the cathode with the plus pole of the accumulator). The output voltage
of the power supply under no load must be set to the e
nd-of-charge voltage plus the voltage
drop at the diode. For an end
-of-charge voltage of, for example, 27.0
VDC (usual for 20° C to
30° C accumulator temperature, although the specifications of the accumulator manufacturer
must always be observed!) and 0.8
V voltage drop at the diode, the power supply without
load should be set to 27.8
V.
