AC-DC Power Supplies PCB Mount TypeInstruction Manual1 Connection for Standard UseL1AC(L)+Vout!To use TEPS series, connection shown in Fig.1.1.C11C12AC(N)-VoutC13LoadAC(L)InputAC(N)+Vout-VoutLoadFig.2.3 Recommended circuit of connect output to FG (TEPS45F/65F)Fig.1.1 Connection for standard use3 Function2 Wiring Input/Output Pin! The TEPS series basically does not require an output capacitor,but the ripple voltage can be reduced by connecting an outputcapacitor.+Vout-VoutCoLoadFig.2.1 Connecting example of an external capacitor 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 2.2.Table 2.1 Connectable external capacitor on the output side (TEPS10F/20F)No.Output voltageTEPS10F/TEPS20F15V0 - 6,800μF212V0 - 4,700μF315V0 - 3,300μF424V0 - 1,000μFTable 2.2 Connectable external capacitor on the output side (TEPS45F/65F)No.Output voltageTEPS45F/TEPS65F15V0 - 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-VoutLoad3.1 Input voltage range!The range is from 85VAC to 264VAC.In cases that conform with safety standard, input voltage range is100VAC to 240VAC (50/60Hz).When DC input is required, Please contact us.!If input value doesn’t fall within above range, a unit may not operatein accordance with specifi cations and/or start hunting or fail.If you need to apply a square waveform input voltage, which iscommonly used in UPS and inverters, please contact us.!When the input voltage changes suddenly, the output voltage accuracymight exceed the specifi cation. Please contact us.If the restart time of the short interruption power failure is less than3 seconds, perform a thorough evaluation.!A power factor improvement circuit (active filter) is not built-in. If youuse multiple units for a single system, standards for input harmoniccurrent may not be satisfied. Please contact us for details.3.2 Inrush current limiting!An inrush current limiting circuit is built-in.!If you need to use a switch on the input side, please select onethat can withstand an input inrush current.! Thermistor is used in the inrush current limiting circuit. When youturn the power ON/OFF repeatedly within a short period of time,please have enough intervals so that a power supply cools downbefore being turned on.3.3 Overcurrent protection!An overcurrent protection circuit is built-in and activated over105% of the rated current. A unit automatically recovers when afault condition is removed.Please do not use a unit in short circuit and/or under an overcurrentcondition.!Hiccup Operation ModeWhen the output voltage drops at overcurrent, the average outputcurrent is reduced by hiccup operation of power supply.Please contact us for details.C13Fig.2.2 Recommended circuit of connect output to FG (TEPS10F/20F)TEPS-22
