In the case of (a) below, the output current shouldbe lower than the rated current of a power supply with the lowestrated current among power supplies that are serially connected.Please make sure that no current exceeding the rated currentfl ows into a power supply.(a)PowerSupply+-5V or lessD1D2LoadPower +D3 D4Supply -D1 - D4 : Use a schottky barrier diodewith low forward voltage.(b)PowerSupply+-PowerSupply+-12V or moreD1LoadPower +D2Supply -D1, D2 : Use a schottky barrier diodewith low forward voltage.Load*If you use a ceramic capacitor, keep the capacitance within therange between about 0.1 to 10 F.*Please adjust the capacitance in light of the effect you want toachieve.*If you need to use an external capacitor whose capacitance exceedsthe range provided in Table 2.2, please contact us.!If the distance between the output and the load is long and thereforethe noise is created on the load side, connect a capacitorexternally to the load as shown below.+Vin +VoutInputLoad-Vin -VoutPowerSupply+-Fig.3.1 Series Operation3.2 Redundancy Operation!You can use the power supplies in redundancy operation by wiringas shown below.PowerSupplyPowerSupply+-+-I1I2I3LoadLoadFig.3.2 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 I3 does not exceed the ratedcurrent of a power supply.I3 [ Rated Current ValueSU .
