适用范围 Application
DDS8688 型单相导轨式智能电表系我公司最新研制开发的新型单相全电子式电能表。该表性能完全符合 GB/T17215.321-2008 国家
标准和国际标准 IEC62053-21 中 1 或 2 级单相电能表的相关技术要求，可直接精确地测量额定频率为 50Hz 或 60Hz 的单相交流电网中
有功电能，由步进式机械计数器或液晶显示总用电量；具有可靠性好、体积小、重量轻、外形美观、安装灵活方便等特点。
DDS8688 Single phase guide rail type intelligent electricity meter it is a new single-phase full electronic watt hour meter newly developed by our
company. The performance of the meter fully complies with the relevant technical requirements of class 1 or 2 single-phase watt hour meters in gb/
t17215.321-2008 national standard and international standard iec62053-21. It can directly and accurately measure the active energy in the single
phase AC network with rated frequency of 50Hz or 60Hz, and the total power consumption is displayed by a stepping mechanical counter or LCD; It has
the characteristics of good reliability, small size, light weight, beautiful appearance, flexible and convenient installation, etc.
