COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Enclosed TypeInstruction Manual? -P3!The specification for series/parallel operation of this power supplyhas been changed. And the Master/slave operation function hasbeen added.[Series Operation]!Wiring method with series operation is shown in Fig.6.6.The DS and SGND must be connected with each other.Please use option part H-PA-14 for connecting between DS andSGND.Please decide one power supply (master power supply) to be operatedon the volume and short circuit between SLV_EN and COMof the other power supply (slave power supply).To short-circuit between SLV_EN and COM, please use optionpart H-SN-53.Use the Master when changing the output voltage.If one of the units operated in series stops or fails, all the powersupplies are stopped by signal information of the DS terminal.To start / stop use the remote ON/OFF control function. ConnectRC 2 and RCG of all power supplies to be operated in series andstart / stop all at the same time.It is necessary to turn the power supply on again to switch themode of Master/slave.When using in series operation, use products of the same modelname.In series operation, the maximum operative number of units is 10.The combined output voltage of series operation is 200V.*Notes on series operation(1) Constant current set value external variable function cannot beused.[Parallel Operation]!Wiring method with series operation is shown in Fig.6.7.The DS,SGND,CB and COM must be connected with each other.Please use option part H-PA-16 for connecting between DS,SGND, CB and COM.Please decide one power supply (master power supply) to be operatedon the volume and short circuit between SLV_EN and COMof the other power supply (slave power supply).To short-circuit between SLV_EN and COM, please use optionpart H-SN-53.Use the Master to change the output voltage.If one of the units operating in parallel stops or fails, all the powersupplies are stopped by signal information of the MS terminal.To start / stop use the remote ON/OFF control function. ConnectRC 2 and RCG of all power supplies to be operated in parallel andstart / stop all at the same time.It is necessary to turn the power supply on again to switch themode of the Master/slave.When using in parallel operation, use products of the same modelname.As variance of output current drew from each power supply ismaximum 10%, the total output current must not exceed the valuedetermined by the following equation.No.3 (Slave)No.2 (Slave)Implement H-PA-14Implement H-SN-53- +(Output current at parallel operation)= (the rated current per unit) X (number of unit) X 0.9!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 is6.- +LoadNo.1 (Master)- +Fig.6.6 Connection method in series (PCA300F, PCA600F)PCA-32
