AC-DC Power Supplies Bus Converter?Power Module TypeInstruction Manual3.2 Parallel operation!Parallel operation is available by connecting the units as shown inFig.3.1.!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 in parallel operation)= (the rated current per unit) X (number of unit) X 0.9F1AC INNoiseFilterFG~ +BridgeDiode~ -F2F2DPF R+VOUTAC1-VOUTAUXAC2ENAFG CBDPF RAC1 +VOUT -VOUTAUXAC2ENAFG CBF3 DiF3 Di+VIN-VINRC1In parallel operation, the maximum operative number of units is 5.!When the output-line impedance is high, the power supplyis become unstable. Use same length and thickness(width)wire(pattern) for the current balance improvement.!Connect each input pin for the lowest possible impedance.When the number of the units in parallel operation increases, inputcurrent increases. Adequate wiring design for input circuitry suchas circuit pattern, wiring and current for equipment is required.!If temperatures of aluminum base plates are different in the powersupply for parallel operation, values of output current will changegreatly.Design radiation to equalize plate temperatures by attaching thesame heatsinks.!Output diode Di is not required if capacity of output smoothing capacitorfor parallel connection is below 2,500μF.F1AC INNoiseFilterFGF2F2F2DPF RAC1 +VOUT -VOUTAUXAC2ENAFG CBDPF RAC1 +VOUT -VOUTAUXAC2ENAFGCBDPF RAC1 +VOUT -VOUTAUXAC2ENAFG CBF3 DiF3 DiF3 Di+VIN-VINRC1F2DPF RAC1 +VOUT-VOUTAUXAC2ENAFG CBFig.3.2 N+1 redundant operation3.3 N+1 redundant operationF3 Di!lt is possible to set N+1 redundant operation for improving reliabilityof power supply system.Connect as shown in Fig.3.2.!Purpose of redundant operation is to ensure stable operation inthe event of single power supply failure.Since extra power supply is reserved for the failure condition, sototal power of redundant operation is equal to N.4 Cleaning!Clean the product with a brush. Prevent liquid from getting into theproduct.Do not soak the product into liquid.!Do not stick solvent to a name plate or a resin case.(If solvent sticks to a name plate or a resin case, it will causeto change the color of the case or to fade letters on name plateaway.)!After cleaning, dry them enough.Fig.3.1 Parallel operationDPF-9
