output voltage falls below 20 V, the device

shuts down latching, the red LED lights up. This

limit voltage of 20 V is independent of the set

output voltage. The 'Short-time overload cur-

rent' 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 seconds after power on.

During these first 10 s, the device responds for

overload as if the switch is "OFF".

Applications

9.1

Parallel connection to increase the power rating

To increase the power rating, 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.

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 reverse currents in the event of a secondary device fault. For this

purpose, a suitable protective circuit (e.g. decoupling diode or DC-capable 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 PSU400M

Manual, 05.2018, C98130-A7601-A1-5-7629 49

9.2

Parallel connection for redundancy

Connecting several 24 V 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 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.

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 line

supplies.

9.3

Series connection for increased voltage

To achieve an output voltage of 48 V DC, two 24 V SITOP power supplies of the same type

can be connected in series.

Depending on the grounding point of the secondary output voltages, voltages of +48 V,

±24 V or -48 V can be realized.

Note

For additional details, see Catalog KT 10.1 Chapter 15 Technical information and configuring

)).

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 PSU400M

Manual, 05.2018, C98130-A7601-A1-5-7629 51

9.4

Overload protection in the 24 V output circuit

If an overload occurs, the electronic current limiting function of the 24 V power supply limits

the 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 outputs (versions with adjustable output

current range for each output from 0.5 - 3 A and 3 - 10 A) is available for this purpose; this

monitors the 24 V branches for overload and short circuit (Figure 9-4 Electronic protection of

24 V loads using 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 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.

9.5

Protection against longer failure of the power supply voltage

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 9-5 24 V buffering to allow

the saving of process data and controlled shutdown of PCs (Page 52)).

Figure 9-5 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

charge.
