如果您购买的LERDN防雷产品不是直接从上海雷尔盾工厂发货,保证产品是LERDN(雷尔盾)真品,请用以下几种方法鉴别真伪:

1、LERDN(雷尔盾)每个产品都是可追溯性的,每个产品的侧面都有唯一的条码序列号,
发送E-mail:spd@lerdn.com 立即查询此产品的真伪信息,可查询到此序列号同一批次从上海雷尔盾工厂发货的产品型号、产品数量、发货的日期、收件人城市等信息,综合以上信息即可判断您购买的产品是否合理的采购渠道,如果从工厂数据库查询不到此序列号,说明您购买的产品是假冒产品。

2、LERDN电源防雷模块外形经典的圆弧设计(图一),如果有两片产品,其中一片旋转180度和另一片完整贴合(图二)
雷尔盾真品
3、产品正面文字是激光打标,文字清晰并不能擦除,如果您购买的产品是油墨印刷的,就是假冒产品
4、产品正面,在显眼的位置,有LERDN(雷尔盾)的商标标识,“LERDN”“雷尔盾”都是上海雷尔盾电气有限公司的商标
5、不在此列出描述的,请致电上海雷尔盾工厂咨询
