In order to protect the unit, installthe slow-blow type fuse on input side (as shown in Table 2.1).In the case of using DC input, please use a DC fuse.Table 2.1(a) Recommended fuse (AC input)ModelTUHS3TUHS5TUHS10TUHS15TUHS25Rated current2A2A2A2A3.15ATable 2.1(b) Recommended fuse (DC input)ModelTUHS3TUHS5TUHS10TUHS15TUHS25Rated current2A2A2A2A2A(2) C1:Input Capacitor(TUHS25)To comply with conducted noise CISPR22-B, EN55022-B, connectcapacitor C1 which is 0.1μF or more at AC input terminal.(3) Cbc:Smoothing capacitor!In order to smooth voltage, connect Cbc between +BC and -BC.Recommended capacitance of Cbc is shown in Table2.2.Hold-uptime and load factor is shown in fi gure 2.1-fi gure 2.10.!Keep the capacitance within the allowable external capacitance.!Select a capacitor of which the ripple voltage does not exceed25Vp-p.!When the power supply is operated under -20degC, it may causethe smoothing voltage unstable due to the characteristic of equivalentseries resistor. Please choose the capacitor which has morethan recommended capacitance.Table 2.2 Input Capacitor CbcNo.ModelRated InputAllowable capacitanceCbcVoltgerange1TUHS3DC400V or more18μF4.7μF to 68μF2 TUHS5 22μF 10μF to 68μF(AC200Vin)3 TUHS10 47μF 22μF to 150μFDC200V or more4 TUHS15 68μF 33μF to 220μF(AC100Vin)5 TUHS25 120μF 47μF to 390μFHold-up time[ms]300F250200150F100F504.F0020406080100load factor[%]Hold-up time[ms]1600140012001000800600400FFF2004.
