EnergyMIDEM2389高精度电量表具有集成接口的极其紧凑的外壳(4个标准宽度单元,即72mm),5(80)直接连接或1(6)变压器,可选的计数器读数配置文件,可以根据颜色变化,显示屏上可以直观的看到检测错误,例如相旋转方向,相故障,极性相反或过载的变压器等,多达33个附加测量值,例如无功功率,视在功率,功率因数和频率等。
EnergyMIDEM2389高精度电量表操作说明收的技术特征
适用于工业和商业用途以及要求苛刻的家庭使用的精度等级B
由于根据MID(合格评定程序模块B和D)在工厂进行了初始校准,因此适合于计费
通过四象限测量来测量能源进出口
通过获取电流和电压的THD以及中性线电流IN的廉价电源监控
通过集成总线接口(M-Bus,Modbus RTU,Modbus TCP,LON或BACnet)或通用脉冲输出(2 ea。S0,具有可调的脉冲速率和持续时间,以及可选的电压范围)进行灵活的通信
具有LED背景照明的高对比度3行LCD(42 x 28 mm)
即使转换比可调,也可以进行校准
可选地集成负载配置文件,具有事件记录器,每天96个注册周期,共60天(例如,过电压或更改CT / VT值)
8种价格输入,可以根据未来的能源市场价格结构进行调整:4种价格(标准控制为硬件控制),4种附加总线的价格(由软件控制)
具有防篡改盖和禁用配置
EnergyMIDEM2389高精度电量表三相电能表,配有4线制系统和变压器连接1(6)A,可用于用于在工业,家庭,商业和建筑物管理应用中获取和计费有功电能。在工业和楼宇管理应用中很常用的传输介质是双绞线铜缆,与电气隔离的FTT-10A收发器一起使用。两个导体都可以连接到任何一个电极上,因此安装是反极性保护的。较大传输距离受电缆电气特性和网络拓扑的影响。多功能电能表EnergyMIDEM系列有EM2289/2281/2381/2389/2387,用户可根据需求进行不同的选择。使用的电缆应符合规定的规格,以防止通信过程中的干扰。由于存在反射的可能性,在任何给定的总线段中只能使用一种电缆类型。
