产品概述

元星电子专注生产高品质电压互感器,该公司是公认的电压互感器制造领域的领导者。元星的微型电压互感器产品线专为高密度电子环境而设计,旨在为需要在空间有限的场所(例如智能电表和紧凑型能源监测设备)内实现高质量、高可靠性、高精度信号转换的B2B制造商解决方案。

作为高性能电压测量互感器,这些产品采用先进的封装技术,提供一流的信号转换精度,达到0.1或0.2级精度(符合IEC 61869-3标准),从而为使用精密仪器的专业人士提供所需的相位稳定性和线性度。虽然微型电压互感器系列体积小巧,但其设计能够提供长达一分钟的2500V隔离电压,以及在500V直流电压下1000MΩ的介电常数。这些特性提供了额外的安全保障,并确保信号的完整性。

该系列电压互感器可以支持表面贴装应用,方便制造商进行正确的电气连接。此外,其非对称安装孔位有助于防止批量生产过程中出现装配错误。与专为配电设计的典型中压电压互感器不同,元星电子的这款空间受限型电压互感器旨在随着电气负载的变化进行精确的二次侧电压检测。该元件的工作频率范围为50 Hz至400 Hz,最大额定负载电阻为100kΩ;因此,它在不同的电气负载条件下均能提供稳定的性能。
