Cov txheej txheem thoob ntiaj teb IEC / EN 61000-4-5 txhais ob lub tshuab hluav taws xob sib txawv: ib qho yog lub tshuab hluav taws xob ua ke (voltage waveform: 1.2/50μs, tam sim no waveform: 8/20μs), thiab lwm yam yog lub tshuab hluav taws xob ua ke ua ke ua tau raws li qhov yuav tsum tau ua ntawm International Telecommunication Union Commission (voltage waveform: 10/700μs, tam sim no waveform: 5/320μs).
Cov qib xeem yog 1, 2, 3, 4 thiab X
Raws li qhov yuav tsum tau muaj ntawm IEC / EN 61000-4-5 tus qauv, kev ntsuas hluav taws xob hluav taws xob ntawm cov kab hluav taws xob thiab kab sib txuas yuav tsum tau sim ua raws. Vim qhov txawv impedances ntawm txoj kab, lub waveforms ntawm surge ntawm cov kab no kuj txawv, uas yuav tsum tau simulated nyias.
(1) Lub tshuab hluav taws xob sib xyaw ua ke ntawm 1.2 / 50μs (voltage yoj) thiab 8/20μs (tam sim no nthwv dej) feem ntau yog siv rau kev kuaj kab hluav taws xob.
