SITOP PSU300S 32 Manual, 12.2016, C98130-A7587-A1-7-7629 Installation 5.2 Output-side connection 5.2 Output-side connection At its output, the SITOP PSU300S 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 (refer to Chapter Technical data (Page 35)). Figure 5-2 Connection of the output voltage (example: 6EP1436-2BA10) The output voltage is connected via the + and - terminals at the output of the power supply (see Figure Connection of the output voltage (example: 6EP1436-2BA10) (Page 33)). 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 supply is grounded.

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. SITOP PSU300S Manual, 12.2016, C98130-A7587-A1-7-7629 53 Applications 9.1 Parallel connection to increase the power rating 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 PSU300S 54 Manual, 12.2016, C98130-A7587-A1-7-7629 Applications 9.2 Parallel connection for redundancy 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 55)). 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 55)). 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.

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 (see (http://w3app.siemens.com/mcms/infocenter/content/en/Pages/order_form.aspx?nodeKey=k ey_518431&infotype=catalogs)). 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. Figure 9-4 Series connection SITOP PSU300S Manual, 12.2016, C98130-A7587-A1-7-7629 57 Applications 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 of the 24 V power supply limits the output current to a maximum value (see Section Technical data (Page 35)). 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 9-5 Electronic protection of 24 V loads using the SITOP PSE200U selectivity module (Page 58)). 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.

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 power supply output (Figure 9-6 Buffering brief power failures using the SITOP PSE201U buffer module (Page 59)). 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.

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 60)). 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.
