COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies PCB Mount TypeInstruction Manual4 Series and ParallelOperation4.1 Series operation!Series operation is available by connecting the outputs of two ormore power supplies as shown below. Output current in seriesconnection should be lower than the lowest rated current in eachunit.(a)(b)PowerSupplyPowerSupplyPowerSupplyLoadLoad4.3 Various connection methods!Using one smoothing capacitor, up to two TUHS can be operated.Shown an example in Fig.4.3.!Total output wattage must be less than the maximum wattage ofTUHS which AC is supplied.!When connect different wattage of TUHS, please input AC into thepower supply which the wattage is higher.!When smoothing capacitor is commonly used, noise may becomebig because of the length of the power line. The noise can beattenuate by connecting Line Filter between TUHS and R1.!Avoid connecting AC input and DC input at the same time becauseit may damage the TUHS or an equipment(Fig.4.4).AC1+VoutAC1+VoutLoadLoadAC2+BC -BC-VoutAC2+BC -BC-VoutF1 R1AC1+VoutAC1+VoutSK1LoadLoadAC2AC2C1(TUHS25) +BC -BC -Vout+BC -BC -VoutF1 D1++CbcCbcPowerSupplyLoad(a) AC input , Cbc common (b) DC input , Cbc commonFig.4.3 TUHS connect methodFig.4.1 Examples of series operation4.2 Parallel operationF1R1AC1+Vout!Parallel operation is not possible.!Redundancy operation is available by wiring as shown below.SK1AC2+BC-BC-VoutLoadPowerSupplyI1 I3+CbcPowerSupplyI2LoadFig.4.4 TUHS Connection prohibition4.4 Long hold-up time connectionFig.4.2 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.I3the rated current value!It is possible that setting the hold-up time of the power supply for along time by connecting like Fig.5.5. Please set the charge currentof the CL to become less than 1A. Please use the diode whichreverse voltage is 600V or more.Please contact us for detail.F1 R1AC1+VoutC1(TUHS25)RLSK1LoadAC2+BC-BC-VoutCL+DLCbc+Fig.4.5 Long hold-up time connectionTUHS-19
