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, U, 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
