AC-DC Power Supplies Enclosed TypeInstruction Manual2 Series Operation andParallel Operation2.1 Series Operation!The power supplies can be used in series connection. The outputcurrent in series operation must be lower than the rated current ofthe power supply with the lowest rated current among the powersupplies connected in series. Make sure no current exceeding therated current fl ows into a power supply.Power +Supply -Power +Supply -LoadPower +Supply -Power +Supply -Fig.2.1 Examples of connecting in series operation2.2 Parallel Operation!Redundant operation is possible by wiring as shown below.PowerSupplyPowerSupply+-+-I1I2I3LoadFig.2.2 Example of redundancy operation!Even a slight difference in output voltage can affect the balancebetween the values of I1 and I2.Make sure the value of I3 does not exceed the rated output currentof the power supply.l3 [ the rated current value?
