UL Approval

UL认证

如果某一电路获得了UL认证,则可以在相应的文件中进行查看。

UL认证

美国安全实验室(UL)为模块、电路和保护元件提供认证。通过认证的设备被称为“UL认可的”,并列在指定的UL文件中。另一种可能性是材料经过UL列出和分类。这些材料可以在特定UL文件中找到,您可以在其中看到例如可燃性等级的分类。单个二极管或晶体管无法获得UL认证,而桥式整流器-也称为格雷茨电路-可以通过UL认证。

德欧泰克大部分桥式整流器通过了UL认证,符合QQIJ2 (组件-电源供应专用领域)标准。

它们可在文件 File No. E175067 (PDF) 中进行查看。

部分桥式整流器还通过了QQQX2(电气隔离半导体器件-元件领域)UL认证。

它们可在文件 File No. E313324 (PDF) 中进行查看。

德欧泰克未获得UL认证的产品使用经过UL列出和分类的材料生产。我们使用具有最严格的可燃性分类UL94V-0的模塑和浇铸化合物:

含有模塑化合物MG21F-02(标准)的元件,请参考文件 File No. E255557 (PDF)

含有模塑化合物EME-120G(无卤素)的元件,请参考文件 File No. E59481 (PDF)

含有浇铸化合物Araldit CW 1195 BD / Härter HW 1196的元件,请参考文 File No. 72789(PDF)
