Energy reference meter IEM

The IEM enables efficient use in various charging infrastructure applications, such as DC wallboxes, high-power chargers, megawatt charging systems and other applications as well as smart metering point operation.

    Installation flexibility

    Thanks to the shunt-based measurement, the DC meter is highly compact. The display and the sensor unit can be installed up to 15 meters apart, which allows a high degree of flexibility during installation. This means that the sensor unit can also be installed in hard-to-reach areas with high ambient loads.

    The top-hat rail design makes it easy to mount the display unit in a wide variety of housings, while the sensor unit can be attached via busbars.
    The CAN interface allows the acquisition of real-time measurement data
    (T, I, V, P, ...) in 10 ms. 

    Additional features:

    • Accuracy class B according to EN 50470 (MID) 
    • Creation and internal storage of load transactions in standardized OCMF format 
    • MID certification, certification in accordance with the German Weights and Measures Act, LNE, UL certification 
    • Communication interfaces: OCMF (RJ45, Ethernet)
    • (IEM-DCR only), CAN info for real-time measurement data, SML (RS485) 
    • Compensation options: 4-wire measurement, parametric compensation 

    Key features IEM

    SMGw infrastructure

    Intelligent DC measuring point operation

    The SMGw retrieves and saves the 15-minute energy values of the DC energy meter via the LMN interface. The 15-minute energy values belong to a specific meter address and are authorized by the gateway administrator. External market participants are provided with the energy values via WAN.
