产品描述
7742安规综合分析仪

针对目前一般安规耐压测试器,仅有耐压测试功能,无法整合完整的安规测试项目,需购置多台仪器,浪费空间增加测试时间,一直为使用者所诟病,华仪电子推出全新7742系列安规综合分析仪,全新六合一功能,包含交流耐压测试(ACW)、直流耐压测试(DCW)、绝缘阻抗测试(IR)、接地阻抗测试(GB)、产品电气性能测试(RUN)、电源泄漏电流测试(LLT)等六种测试功能;其中7742的接地阻抗测试(GB)可输出40A,以满足各个产业产品安规的测试要求,仅需一台仪器即可执行多项安规的测试,将可大幅降低测试时间、提高生产效率,、以及有效的解决产品安规测试的问题。

7742安规综合分析仪的超大型Graphic LCD视窗,可完整显示所有的设定参数和测试结果,全机采用线性放大器技术设计提高输出的准确性、稳定度,以及专利认证的防高压触电功能Smart GFI线路,更可让使用者在误触高压时,立刻切断输出,确保使用者操作安全。若搭配华仪电子全新开发的SPACE-9170安规自动化测试软体,可将所有的测试参数及测试资料进行储存、呼叫;还可将测试后的数值作资料的分析统计。华仪电子已将安规测试引领到自动化测试的领域,更加满足工程师对精密测试生产线对大量资料处理的需求,全新的7742安规综合分析是客户最佳选择。
