AC-DC Power Supplies Enclosed TypeInstruction Manual3 Series/Parallel OperationNo.nImplement H-PA-143.1 Series Operation!The series operation is available to obtain higher output voltage.However care should be taken as follows:Notes of (a) :In case of malfunction (Protection circuit activation orFailure),please stop the operation and replace the failed powersupply.PowerSupplyPowerSupply+-+-Power SupplyDS SGND+-DS SGND+Power Supply-(a)(c)LoadLoadPowerSupplyPowerSupply+-+-(b)Fig.3.1 Examples of connecting in series operationLoadLoad!In the case of Figure 3.1 (C), if one power supply stops or fails, allremaining power supplies also stop.The DS and SGND must be connected with each other as shownin Fig.3.2.Option part“H-PA-14”can be used for connecting between DSand SGND.!When turning on and off by remote ON/OFF control function, connectRC 2 and RCG of all power supplies to be operated in seriesand start / stop all at the same time.!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.- +No.2-Load+No.1- +Fig.3.2 Connection method in series (PCA300F, PCA600F)* Notes on series operation(1) Constant current set value external variable function cannot beused.3.2 Parallel Operation!Wiring method with parallel operation is shown in Fig.3.3.The CB and SGND must be connected with each other.Please use option part H-PA-15 for connecting between CB andSGND.!When turning on and off by remote ON/OFF control function, connectRC 2 and RCG of all power supplies to be operated in paralleland start / stop at the same time.The difference between the maximum and minimum of the outputvoltage of each power supply connected in parallel should bewithin 1%.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.(Output current at parallel operation)= (the rated current per unit)×(number of unit)×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.PCA-26
