具有激光光源的设备还应按GB 7247分类为1、2、3a、3b、4类。 耐压500V/100mA,min基本绝缘通过即可厂
这样的问题也问!
你自己去找个类似的产品的tuv或者UL的报告看下再来问吧. 首先要确定你申请认证的标准,如果是信息类产品,满足功能绝缘500V/10mA耐压测试1min就可以,如果是家电类产品,满足基本绝缘500V/10mA耐压测试1min Do you mean the safety requirement of EMC Surge test?
If safety, you must know your working voltage or rated voltage...
If EMC surge, then both common and differential should be considered ,and you can reference IEC 61000-4-5 既然已經是class III, 表示supply by SELV voltage, 本身即為二次測的產品, 雷擊的防護當然已經(也必須)在前端的供應端評估
(例如: adaptor),
二次測的connector 就必須視種類評估, 例如: TNV 線路即會有要求...
