LED Indicator Lamps Semiconductor Economy Energy Indicator  Description  AD127 series lights LED light-emitting chips are used as the light source,long life,low power consumption,small size ,light weight,is the XD type all types of incandescent and neon signal light replacement products,using high-strength polycarbonate lampshade,has a good impact performance,built rivet-type wiring,more secure and convenient. This series of signal lights are suitable for electricity, telecommunications, machine tools, shipbuilding, textile, printing, mining machinery and other equipment for the signal indication,notice the signal,accident signal and other instructions with the signal. Technical Parameter Model NameAD127Voltage40VColorblue green red white yellowVisual stylesA B C D EContinuous working life≥30,000HPower frequency withstand voltage2.5KV(AC effective value),1minUse frequency(AC)50-60HzRated working current≤20mALight height≥100cd/m²Insulation resistanceUi≤60V 5mΩ 60≤Ui≤660V 50mΩFeatures ●AC/DC signal is resistance step-down type,AC signal of resistance capacity type.●When voltage 110V and above, AC/DC type lamp shell temperature rise is higher than AC signal lamp.●AC type signal using frequency 50-60Hz,used in other-frequency bands will damage the signal lights.●Anti-interference signal light general threshold in 40V or less, if a high threshold,please explain further.Recommended threshold is not too high,such as the interference voltage is too high,check the wiring conditions.●AC double color lamp do not allow the wiring error, otherwise it will damage the signal lampApplicable Working Ambient temperature-25~+55℃, the average value cannot exceed to +35℃ within 24hAltitude≤2,000mRelative humidity≤95%Installation locationMount on the place where has no obvious vibration or impact
