For mounting positions that deviate from the standard mounting position, derating factors

(reduction of the output power or the permissible ambient temperature) must be observed in

accordance with the following diagrams.

Note

In the case of mounting positions

that deviate from the standard mounting position, reduced

mechanical resistance of the devices against vibration and shock must be expected.

Particularly when installing on a vertically fastened standard mounting rail, additional

measures may be required,

e.g. to prevent the device from slipping on the standard

mounting rail.

Operating Instructions, 07.2014, C98130-A7589-A1-5-7629 37

5.2

Output-side connection

At its output, the SITOP PSU100S 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 limitation limits

the output current to a maximum value (refer to chapter Technical data (Page 39)).

Figure 5-2 Connecting the output voltage (examples 6EP1334-2BA20 and 6EP1336-2BA10)

The output voltage is connected via the + and - terminals at the output of the power supply

(see Figure 5-2 Connecting the output voltage (examples 6EP1334-2BA20 and 6EP1336-

2BA10) (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 SITO

P power supply 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.

The device supplies a constant output voltage until the current limit is reached. In the event

of an overload, the output current and the output voltage are reduced.

When the output voltage falls below approx. 10 V, the 6EP1336-2BA10 device switches off,

and automatically restarts. This response is repeated as long as the overload condition is

present.

Operating Instructions, 07.2014, C98130-A7589-A1-5-7629 61

Applications

9.1

Parallel connection to increase power rating

To increase the power rating, two SITOP PSU100S 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.

Figure 9-1 Parallel connection

Note

It is not permissible to take into account simultaneous overload capability (Extra

Power 150%

for 5

s/min) of several power supplies connected in parallel when configuring the power

supply system.

NOTICE

Protective circuit for the parallel connection of more than two power supplies

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.

Applications

9.2 Parallel connection for redundancy

SITOP PSU100S

Operating Instructions, 07.2014, C98130-A7589-A1-5-7629 63

9.2

Parallel connection for redundancy

Connecting several SITOP PSU100S 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 SITOP PSE202U redundancy module (Page 63)). 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.

Note

For a high reliability of the supply, it is recommended that the redundant switched power

supplies are fused separately on the line

-side and, if possible, be connected to different

power supply networks.

9.3

Series connection for increased voltage

To achieve an output voltage of 48 V DC, two 24 V SITOP PSU100S 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 VDC according to EN 60950-1 cannot be guaranteed in the case of a

fault.

9.4 Overload protection in the 24 V output circuit

SITOP PSU100S

Operating Instructions, 07.2014, C98130-A7589-A1-5-7629 65

9.4

Overload protection in the 24 V output circuit

If overload occurs, the electronic current limiting of the SITOP PSU100S power supply limits

the output current to a maximum value (refer to chapter 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 channels (versions with adjustable output

current range for each channel from 0.5-3 A and 3-10 A) is available; this monitors the 24 V

branches for overloading and short-circuiting (Figure 9-4 Electronic protection of 24 V loads

using the SITOP PSE200U selectivity module (Page 65)). 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 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.

9.5

Protection against short-time voltage dips

For a drop in the line-side supply voltage, the SITOP PSU100S 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 9-5 Buffering brief power failures using the

SITOP PSE201U buffer module (Page 66)). 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 9-6 24 V buffering to allow

the saving of process data and controlled shutdown of PCs (Page 67)).

Figure 9-6 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.
