Pleasesee Optional Parts for details.*1 If the output of an external power supply is within the rangeof 4.5 - 12.5V, you do not need a current limiting resistor R. Ifthe output exceeds 12.5V, however, please connect the currentlimiting resistor R.To calculate a current limiting resistance value, please use the followingequation.? -T1 (LFA300F)-Option -T models have horizontally positioned screws on a terminalblock.-Please contact us for details about appearance.FGAC (N)AC (L)Fig.6.4 lifting method-V+VR[W]=Vcc-(1.1+RiX0.005)0.005Fig.6.5 Example of option -T1* Please wire carefully. If you wire wrongly, the internal componentsof a unit may be damaged.!Remote ON/OFF circuits (RC+ and RC-) are isolated from input,output and FG.? -R2 (LFA100F, LFA150F, LFA240F, LFA300F)-The usege is the same as option -R, please refer to Option -R.-Reducing standby power is possible by OFF signal of the remotecontrol.-Start up time by ON signal in remote control is 350ms(typ).-The latch condition in overvoltage protection is removed by togglingON/OFF signal of remote control.-Standby powerLFA100F,LFA150F,LFA240F0.2Wtyp (AC100V), 0.7Wtyp (AC200V)LFA300F0.25Wtyp (AC100V), 1.1Wtyp (AC200V)? -T (LFA240F, LFA300F)-Option -T models have vertically positioned screws on a terminalblock.-Please contact us for details about appearance.FGAC (N)-VAC (L)+VFig.6.3 Example of option -TLFA-336.2 Others!This power supply is the rugged PCB type. Do not drop conductiveobjects in the power supply.!At light load, there remains high voltage inside the power supplyfor a few minutes after power OFF.So, at maintenance, take care about electric shock.!This power supply is manufactured by SMD technology. Thestress to PCB like twisting or bending causes the defect of theunit, so handle the unit with care.-Tighten all the screws in the screw hole.-Install it so that PCB may become parallel to the clamp face.-Avoid the impact such as drops.!While turning on the electricity, and for a while after turning off,please don’t touch the inside of a power supply because there aresome hot parts in that.!When a mass capacitor is connected with the output terminal(load side), the output might become the stop or an unstable operation.Please contact us for details when you connect the capacitor.? LFA10F, LFA15F!When these power supplies are connected to the input terminal inparallel, the total capacitance between line and line becomes big.Therefore, the electrical discharge resistance on the safety standardmight become necessary.Please contact us for details when safety standard is necessary atmultiple units usage.
