Prometer 100

Class 0.2S / 0.5S grid meter in wall and rack versions, with DLMS and Modbus together on RS-485 and Ethernet. IEC 61850 optional.

CEWE Prometer 100 wall-mount and rack-mount high-accuracy grid meter

OVERVIEW

Prometer 100 is a four-quadrant grid meter for substations, power plants and HV/MV energy transfer points. DLMS/COSEM and Modbus run simultaneously on its RS-485 and Ethernet ports, and on the wall version two hot-pluggable communication modules, one of which can be an optional IEC 61850 module, add redundant data paths. The rack version has a fixed configuration.
