LMN-PowerEye
12 V LMN test, measurement and load system
LMN-PowerEye is used to test the LMN (local metrological network) behaviour of smart meter gateways (SMGw) under defined load conditions. The system acquires voltage, current and power on the SMGw and meter side and provides a software-controlled additional load.
The system is intended for laboratory, integration and field tests in a 12 V LMN environment. It is not a universal high-power electronic load and is not intended for billing subject to legal metrology (eichpflichtige Abrechnung).
It is supplied as a complete system: control/measurement module with display, additional load module, LMN cables, connection leads and RS-485 cable set. It is controlled by PC software via RS-485 (Modbus RTU).
