The stress to P.C.B like twisting or bending causes the defect of the unit, so handle the unit with care.*Make sure necessary tests will be carried out on your end equipment with the power supply installed in accordance with any required EMC/EMI regulations.LFA-4Specification is changed atoption, refer to InstructionManual.MODELLFA15F-3R3-YLFA15F-5LFA15F-12LFA15F-15LFA15F-24MAX OUTPUT WATTAGE[W]9.91515.61516.8DC OUTPUT3.3V 3A5V 3A12V 1.3A15V 1A24V 0.7ASPECIFICATIONSMODELLFA15F-3R3-YLFA15F-5LFA15F-12LFA15F-15LFA15F-24VOLTAGE[V]AC85 - 264 1f (Refer to“Derating”, Instruction Manual 1 and 3) *3CURRENT[A]FREQUENCY[Hz]50 / 60 (47 - 440)INPUTACIN 100V 68.0typ 73.0typ 76.0typ 77.0typ 78.0typEFFICIENCY[%]ACIN 200V 69.0typ 76.0typ 78.5typ 80.0typ 81.5typINRUSH CURRENT[A]LEAKAGE CURRENT[mA]0.15/0.30max (ACIN 100V / 240V 60Hz, Io=100%, According to IEC62368-1 and DEN-AN)VOLTAGE[V]3.35121524CURRENT[A]3.03.01.31.00.7LINE REGULATION[mV]*520max20max48max60max96maxLOAD REGULATION[mV]*540max40max100max120max150max0 to +50C80max80max120max120max120maxRIPPLE[mVp-p]-10 - 0C 140max 140max 160max 160max 160max*1Io=0 - 35% 190max 160max 240max 240max 280max0 to +50C120max120max150max150max150maxOUTPUTRIPPLE NOISE[mVp-p]-10 - 0C 160max 160max 180max 180max 180max*1Io=0 - 35% 240max 240max 300max 300max 320maxTEMPERATURE REGULATION[mV]DRIFT[mV]*220max20max48max60max96maxSTART-UP TIME[ms]200typ (ACIN 100V, Io=100%) *Start-up time is 700ms typ for less than 1minute of applying input again from turning off the input voltage.HOLD-UP TIME[ms]20typ (ACIN 100V, Io=100%)OUTPUT VOLTAGE ADJUSTMENT RANGE[V]2.85 to 3.63Fixed (“Y”option is available for adjusting output voltage between±10%)OUTPUT VOLTAGE SETTING[V]3.30 to 3.404.90 to 5.3011.50 to 12.5014.40 to 15.6023.00 to 25.00OVERCURRENT PROTECTIONWorks over 105% of rating and recovers automaticallyPROTECTIONCIRCUIT ANDOTHERSISOLATIONENVIRONMENTSAFETY ANDNOISEREGULATIONSOTHERSOVERVOLTAGE PROTECTION4.00 to 5.255.75 to 7.0013.80 to 16.8017.25 to 21.0027.60 to 33.60OPERATING INDICATIONNot providedREMOTE SENSINGNot providedREMOTE ON/OFFNot providedINPUT-OUTPUTAC3,000V 1minute, Cutoff current = 10mA, DC500V 50MW min (At Room Temperature)INPUT-FGAC2,000V 1minute, Cutoff current = 10mA, DC500V 50MW min (At Room Temperature)OUTPUT-FGAC500V 1minute, Cutoff current = 25mA, DC500V 50MW min (At Room Temperature)OPERATING TEMP.,HUMID.AND ALTITUDE-10 to +70C, 20 - 90%RH (Non condensing) (Refer to“Derating”, Instruction Manual 3), 3,000m (10,000 feet) max *3STORAGE TEMP.,HUMID.AND ALTITUDE-20 to +75C, 20 - 90%RH (Non condensing), 9,000m (30,000 feet) maxVIBRATION10 - 55Hz, 19.6m/s 2 (2G), 3minutes period, 60minutes each along X, Y and Z axisIMPACT196.1m/s 2 (20G), 11ms, once each X, Y and Z axisAGENCY APPROVALSUL60950-1, C-UL (CSA60950-1), EN62368-1 Complies with DEN-ANCONDUCTED NOISEComplies with FCC-B, VCCI-B, CISPR-B, EN55011-B, EN55022-BHARMONIC ATTENUATORComplies with IEC61000-3-2 (Class A) *6 (Not built-in to active fi lter) *4CASE SIZE/WEIGHT50X22X87.5mm [1.97X0.87X3.44 inches] (WXHXD) / 80g max (with chassis & cover : 190g max)COOLING METHODConvection (Refer to“Derating”, Instruction Manual 3) *3*1 This is the value that measured on measuring board withcapacitor of 22mF at 150mm from output terminal.Measured by 20MHz oscilloscope or Ripple-Noise meter(Equivalent to KEISOKU-GIKEN: RM103).A circuit reducing standby power is built in this unit.Therefore, the internal switch element is intermittentoperated, and the Ripple/Ripple Noise specification in loadfactor Io=0-35% is different.Please refer to the Instruction Manual 1.7.*2 Drift is the change in DC output for an eight hour period aftera half-hour warm-up at 25C, with the input voltage heldconstant at the rated input/output.*3 Derating is required.*4 When two or more units are operating it may not comply withthe IEC61000-3-2.? 214 ?Please contact us for details.*5 Please contact us about dynamic load and input response.*6 Please contact us about another class.* To meet the specifications. Do not operate over-loaded condition.* Parallel operation is not possible.* Derating is required when operated with chassis and cover.* Sound noise may be generated by power supply in case of pulseload.
