AC-DC Power Supplies Open FrameInstruction Manual6.2 Output side attaching external capacitor!Depending on the capacitance of the external capacitor, resonancemay occur due to ESR, ESL, and wiring inductance, soplease be careful of ripple increase.!If the external capacitor is too large, the power supply might notstart up.+Vout-Vout+CoLoadFig.6.13 Output side external capacitor connection methodTable 6.32 Connectable External capacitor on the output side [μF](LHA10F, LHA15F, LHA30F, LHA50F)ModelLHA10FLHA15FLHA30FLHA50FOutput voltage3.3V0 to 30000 to 40000 to 28000 to 61005V0 to 30000 to 40000 to 13000 to 280012V0 to 15000 to 20000 to 13000 to 280015V0 to 15000 to 20000 to 13000 to 280024V0 to 10000 to 15000 to 9200 to 190036V---0 to 110048V---0 to 9206.3 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.Be careful of electric shock during maintenance.!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.-Please tighten screws in all mounting holes.ModelLHA10F, LHA15F, LHA30FLHA50F, LHA75F, LHA100F,LHA150F, LHA300FMounting holes2 positions4 positions-Install it so that PCB may become parallel to the clamp face.-Avoid dropping unit.!While turning on the electricity, and for a while after turning off,please don’t touch the inside of power supply because some componentscould be hot.Table 6.33 Connectable External capacitor on the output side [μF](LHA75F, LHA100F, LHA150F, LHA300F)ModelLHA75FLHA100FLHA150FLHA300FOutput voltage3.3V0 to 9200---5V0 to 92000 to 24000--12V0 to 42000 to 87000 to 63000 to 560015V0 to 42000 to 8700--24V0 to 28000 to 63000 to 28000 to 490036V0 to 16000 to 35000 to 1600-48V0 to 12000 to 28000 to 10000 to 1400LHA-42
