NOTICE

Thermal overload possible

Note

It is only permissible to use an insulated screwdriver when actuating the potentiometer.

2.3 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)

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).

For notes on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data for 6EP1436-3BA10, 6EP1456-3BA00, 6EP1424-3BA00, 6EP1436-3BA20 (Page 10) and Figure 2-3 Terminal data for 6EP1437-3BA20 (Page 10).

Figure 2-6 Selector switch (example 6EP1456-3BA00 / 6EP1437-3BA20)

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

influences the output characteristic in the load range

influences the output characteristic in the overload range

'Soft' characteristic curve (see, e.g. Figure 6-8 6EP1436-3BA10 parallel operation output characteristic curve (Page 46)) for the parallel operation 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 highest output voltage can normally no longer be

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 seconds after power on. During these first 10 s, the device responds for overload as if the switch is OFF.

Delivery state

'Hard' characteristic curve (see, e.g. Figure 6-3 6EP1436-3BA10 single operation output characteristic curve (Page 44)) for normal operation (single operation): The output voltage is independent of the output current.

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).

WARNING

Hazard due to electric shock

5.1

Line-side connection

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.

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.

SITOP PSU300M/300B Manual, 11.2014, C98130-A7574-A2-2-7629

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

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 grounded. In this case, ideally, the grounding at the output should be directly connected from terminal " system (PE) of the plant or system.

5.2 Output-side connection

At its output, the SITOP PSU300M/300B power supply provides an isolated (= nongrounded) 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.

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

9.1 Parallel connection to increase power rating

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.

Parallel connection for redundancy

Note

For a high reliability of the supply, it is recommended that the redundant switched power supplies are fused separately on the li power supply networks.

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.

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 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.

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.

9.4

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 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

9.5 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

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 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.

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)).
