COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Open FrameInstruction Manual2 Wiring Input/Output Pin!The TECS series basically does not require an output capacitor,but the ripple voltage can be reduced by connecting an output capacitor.+Vout-VoutCoLoadFig.2.1 Connecting example of an external capactior to the output side!If output current decreases rapidly, output voltage rises transientlyand the overvoltage protection circuit may operate. In this case,please Install an external capacitor Co between +Vout and -Voutpins for stable operation of the power supply.!Connectable external capacitor on the output side is shown inTable 2.1.Table 2.1 Connectable external capacitor on the output side (TECS10F/20F)No.Output voltageTECS10F/TECS20F15V0 - 6,800μF212V0 - 4,700μF315V0 - 3,300μF424V0 - 1,000μFTable 2.2 Connectable external capacitor on the output side (TECS45F/65F)No.Output voltageTECS45F/TECS65F15V0 - 6,800μF212V0 - 4,700μF324V0 - 1,000μF!When connect the output to FG of an equipment, a noise may becomebig. The noise can be reduced by connecting external fi lterand/or grounding capacitor on the input side.L1C1AC(L)AC(N)+Vout-VoutLoad3 Series / Parallel andRedundancy Operation3.1 Series operation!You can use power supplies in series operation. The output currentin series operation should be lower than the rated current of apower supply with the lowest rated current among power suppliesthat are serially connected. Please make sure that no current exceedingthe rated current fl ows into a power supply.Power +Supply -Power +Supply -(a)LoadPower +Supply -Power +Supply -(b)Fig.3.1 Examples of connecting in series operation3.2 Parallel and redundancy operation!Parallel operation is not possible.!Redundancy operation is available by wiring as shown below.PowerSupplyPowerSupply+-+-I1I2I3LoadFig.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 valueLoadLoadC13Fig.2.2 Recommended circuit of connect output to FG (TECS10F/20F)L1AC(L)+VoutC11C12AC(N)-VoutC13LoadFig.2.3 Recommended circuit of connect output to FG (TECS45F/65F)TECS-16
