PDA15F, PDA30F, PDA50F, PDA100F,PDA150F! Parallel operation is not possible.! Redundancy operation is available by wiring as shown below.! If you use the remote sensing function in parallel operation, connectparallelly +S and -S of slave power supplies must be connectedto master and connect the sensing wire from the masterunit to the load.! You cannot parallelly operate power supplies with different outputvoltage or electrical power.PowerSupply+-I1I3Install H-SN-19No.1(Master)Install H-PA-3No.2(Slave)Remove H-SN-19Install H-PA-3No.5(Slave)Remove H-SN-19LoadPowerSupply+-I2(ー)(＋)LoadFig.3.2 Example of 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 [ the rated current value? PDA300F, PDA600F! You can use the power supplies in parallel operation by connectingunits as shown in Fig.3.3.Please parallelly connect±S, VB and CB of each power supply inparallel operation and connect±S and±M on CN1 of the masterpower supply.When the power supplies are shipped from a factory, they comewith a dedicated harness (H-SN-19) being mounted on CN1.Please remove the dedicated harness (H-SN-19), which is mountedon CN1 of the slave power supply, and use an optional harness,H-PA-3, to connect±S, VB and CB parallelly.Differences in the output current values among the power suppliesin parallel connection are 10% at most. Please make sure thatthe sum of the output current values does not exceed a value obtainedfrom the right side of the following equation.Fig.3.3 Example of parallel connection(PDA600F)3.3 N+1 Parallel Redundancy Operation? PDA300F,PDA600F! You can have N+1 redundancy operation for improved systemreliability.! If you add one extra power supply in parallel operation, even ifone of the power supplies in your system fails, the remaining nonfailedpower supplies continue to sustain the system. If one of thepower supplies stops operating, the output voltage may changeabout 5%.! When unit replacement is required due to unit failure, input voltagefor all units must be cut off.!After replacement, please make sure that all wirings are completedcorrectly, before re-applying input voltage.Hot-swap or Hot-plug is not available.!If 2 or more units failed, suffi cient power could not be provided tothe system. Therefore, please replace the failed unit immediatelyin case where unit failure is found.!If you have any questions about series, parallel and N+1 redundancyoperations, please contact us.(Output current in parallel operation)= (Rated current per unit) X (Number of unit) X0.9! 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 is5.! You can adjust the output voltage in parallel operation by adjustinga potentiometer of just one power supply.To do so, select one power supply as the master unit and turn thepotentiometers of the other (slave) power supplies clockwise tothe end.Once you have done this, you can adjust the output voltage byturning the potentiometer of the master unit.PDA-26
