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 unit (DU) and the sensor unit (SU) can be installed up to 15 meters apart offering a high degree of flexibility in installation. This means that the sensor unit can also be installed in hard-to-reach areas with challenging environmental conditions. Additionally, the CAN interface enables the measurement of real-time data (e.g., T, I, U, P, ...) with a sampling rate of 10 ms.
Characteristics:
- Accuracy class B according to EN 50470 (MID)
- Creation and internal storage of charging transactions in standardized OCMF format
- MID certification, certification in accordance with the German Calibration Law, LNE
- Communication interfaces: OCMF (RJ45, Ethernet, IEM-DCR only), CAN info for real-time measurement data
- Compensation options: 4-wire measurement, parametric compensation
