应用场合
电子电能表主要用于采集有功和无功电能消耗的数据,其标准的适用范围是在能源领域的管理,成本中心的分析。有各种不同的通讯可能性,以避免人工现场读数的消耗时间和成本。
有功电能脉冲信号可以通过两个脉冲输出,如:DDC, PLC, SCADA 系统或数据采集器ProData®,通过中控系统的协议M-Bus总线, EIB-KNX 和 Modbus RTU协议的设备都可以通过外部的通讯模块来连接,它使用光纤接口,并提供相应的现场总线接口,可记录更多的数据,如电压、电流、功率、功率因数和频率以及有功电能无功电能等,使用总线的通讯模块。

Applications
The electronic energy meters of the EM series are suitable for the measurement of effective- and reactive-energy consumption. Measurement is laid out for a 1- and 3- phase system with a voltage of L-N 184-276VAC. The current inputs are designed for direct connection or for measurement through current transformers. Installation is undertaken on DIN-rails, whereby the extremely compact construction is of particular value.
There are two versions available: a non-calibrated version and a calibrated version (MID). All meters in the EM series can be sealed. The effective and reactive energy is available in two tariffs and in four quadrants. The accuracy of the meters is class 1 for effective energy and class 2 for reactive energy.
数据采集记录
所有电能表把计数值保存在非掉电存储器中,标准版读数不能复位,在非标准版的读数可以复位。校准版的电流互感器的变比是固定的。
