主要特点:
■ 国际化安规标准:满足GB4706.1-2005等国内外安规标准测试;符合JJG795-2004、JJG984-2004、JJG843-2007、
JJG690-2003安规计量检定规程要求;
■ 测试迅速:以ARM7TDMI内核的微控制器为核心,测试通道实时捕获被测设备在测试过程中各参数变化情况,
几秒钟内准确完成一项测试,最短在十秒内完成全部项目测试(耐压、绝缘、接地、泄漏、功率、启动六项测
试),能满足生产线对测试时间的要求;
■ 输出方式先进:摒弃了传统仪表自耦变压器调节输出信号的方法,采用正弦脉宽调制(SPWM)技术产生50Hz
或60Hz标准正弦波,经大功率MOS管驱动输出,实现了高电压和大电流的无触点调节,大大提高了仪器的
可靠性;
■ 运行可靠:GX9641B安全性能综合测试仪整机线路采用了多种抗干扰措施,抗干扰能力强;同时具有硬件和软件保护,运行
安全可靠;
■ 操作简单:本系列测试仪采用背光式液晶显示屏,光线柔和,清晰度高,受环境光线影响小;中文菜单提示
操作步骤,光标指示,简明易懂;全屏显示测试结果,多组测试条件记忆,能方便地实现多种电器机型的测试;
■ 使用安全:自动过压、过流保护,使用更加安全;
■ 智能判别:可设定电压、电流下限判定,消除产品漏检;对产品测试失败,进行智能分析,声光报警。
■GX9641B:耐压、绝缘、接地、泄漏四合一(可选隔离变压器容量:2KVA,4KVA,6KVA)标配为2KVA
■GX9651B:耐压、绝缘、接地、泄漏、功率、启动六合一(可选隔离变压器容量:2KVA,4KVA,6KVA)标
配为2KVA
