The output currentin series operation should be lower than the rated current of apower supply with the lowest rated current among the power suppliesthat are serially connected. Please make sure that no currentexceeding the rated current fl ows into a power supply.Power +Supply -Power +Supply -(a)LoadPower +Supply -Power +Supply -(b)Fig.3.1 Examples of connecting in series operation3.2 Parallel Operation!There is no current balance function.When operating in parallel, such as diode-OR, please use on theoutput voltage was adjusted enough to balance the current.Exceeds the rated output current, the output is shut down.!Redundancy operation is available by wiring as shown below.PowerSupplyPowerSupply+-+-I1I2I3LoadFig.3.2 Example of connecting in redundancy operationEven 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 valueLoad LoadKH-24
