Solution
? 方案滿(man)足IEC61000-4-5、GBT17626.5等浪(lang)(lang)涌測(ce)試(shi)標準; ? 在差模防(fang)護中,采用(yong)鉗(qian)位器件壓敏(min)電(dian)(dian)阻MOV,響應速度快,降(jiang)低(di)L與N線之(zhi)間的(de)浪(lang)(lang)涌電(dian)(dian)壓; ? 在共模防(fang)護中,采用(yong)壓敏(min)電(dian)(dian)阻MOV和陶瓷(ci)氣(qi)體放(fang)電(dian)(dian)管GDT串聯到PCB地或者設(she)備外殼,阻止壓敏(min)電(dian)(dian)阻MOV的(de)漏電(dian)(dian)流,滿(man)足安規要(yao)求(qiu); ? 電(dian)(dian)源方案可通(tong)過1.2/50-8/20μS組合(he)波差模、共模6.0KV浪(lang)(lang)涌測(ce)試(shi); PS:在有絕(jue)緣等級耐壓測(ce)試(shi)AC1500V要(yao)求(qiu)時,陶瓷(ci)氣(qi)體放(fang)電(dian)(dian)管GDT建議選用(yong)DC3500V電(dian)(dian)壓;
