AC-DC Power Supplies Enclosed TypeInstruction Manual2 Peak Current? PBA300F-24, PBA600F-24, PBA1000F-24,PBA1500F-24/36 and PBA1500T-24!The units can generate the peak current under the following conditions.-AC170 - 264V-t1[10 [sec]-Ip[Rated peak current-Iave[Rated currentt1-Duty= X100 [%] [35%t1+t2[A]Output current3 Series/ParallelOperation3.1 Series OperationFig.2.1 Peak current!You can use a power supply in series operation. The output currentin series operation should be lower than the rated current of apower supply with the lowest rated current among power suppliesthat are serially connected. Please make sure that no current exceedingthe rated current fl ows into a power supply.Power +Supply -Power +Supply -t1(a)t2LoadPower +Supply -Power +Supply -Ip:Peak currentIave:Average current(b)Fig.3.1 Examples of connecting in series operationLoad Load3.2 Parallel Operation/Master-slave Operation? PBA10F, PBA15F, PBW15F, PBA30F,PBW30F, PBA50F, PBW50F, PBA75F,PBA100F and PBA150F!Parallel operation is not possible.!Redundancy operation is available by wiring as shown below.PowerSupplyPowerSupply+-+-I1I2Fig.3.2 Example of connecting in redundancy operation!Even a slight difference in output voltage can affect the balancebetween the values of I1 and I2.Please make sure that the value of l3 does not exceed the ratedcurrent of a power supply.l3 [ rated current value? PBA300F, PBA600F, PBA1000F, PBA1500Fand PBA1500T!You can use the power supplies in parallel operation by connectingunits as shown in Fig.3.3.Please parallelly connect±S, VB and CB of each power supply inparallel operation and connect±S and±M on CN1 of the masterpower supply.When the power supplies are shipped from a factory, they comewith a dedicated harness (H-SN-19) being mounted on CN1.Please remove the dedicated harness (H-SN-19), which is mountedon CN1 of the slave power supply, and use an optional harness,H-PA-3, to connect±S, VB and CB parallelly.Differences in the output current values among the power suppliesin parallel connection are 10% at most. Please make sure thatthe sum of the output current values does not exceed a value obtainedfrom the right side of the following equation.(Output current in parallel operation)= (Rated current per unit) X (Number of unit) X0.9!When the number of units in parallel operation increases, the inputcurrent also increases. Please design input circuitry (includingcircuit pattern, wiring and current capacity for equipment) carefully.!Please make sure that the wiring impedance of a load from eachpower supply becomes even. Otherwise, the output current balancecircuit may become inoperative.!The maximum number of units you can use in parallel operation is5.I3LoadPBA/PBW-41
