COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Medical 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 flows into a power supply.Power +Supply -Power +Supply -3 Life Expectancy andWarranty■WarrantyLoadPower +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■Parallel operation is not possible.LoadLoad4 Ground■When installing the power supply with your unit, ensure that theinput mounting hole FG is connected to safety ground of the unit.Except for -E option.5 Options and Others5.1 Outline of Options●-C・With the -C option, the internal PCB has a conformal coatingfor anti-humidity.●-E (UMA30F, UMA60F)・The -E option is for IEC Class ll equipment.●-T・The -T Option has changed the I /O interface from the connectorto the terminal block Type.・Please contact us for details about appearance.●-SN・-SN indicates a type with chassis and cover(Refer to externalview).・In optional -SN case, please refer to“Derating”.・The -SN option cannot be used in combination with the -E option.●-Y (UMA30F, UMA60F)・The -Y option allows for the output voltage adjustment and outputvoltage setting by the built-in potentiometer.Table 5.1 Output voltage adjustment range and output voltage settingOutput voltage5.2 Medical Isolation Grade■UMA series meets 2MOPP2MOPPOutput voltageadjustment range [V]Output voltagesetting [V]5V4.5 to 5.55.00 to 5.157.5V6.75 to 8.257.50 to 7.8012V10.8 to 13.212.00 to 12.4815V13.5 to 16.515.00 to 15.6024V21.6 to 26.424.00 to 24.9636V32.4 to 39.636.00 to 37.4448V43.2 to 52.848.00 to 49.92CoolingMethodVoltageTable 3.1 WarrantyAverage ambienttemperatureLoad factorIo≦75%Warranty [years]Load factor75%
