DEM2A302 Single-Phase Direct-Connected Fast-Refresh MID DIN-Rail Energy Meter
DEM2A302 is a single-phase direct-connected MID-certified DIN-rail energy meter for fast-refresh energy and power monitoring applications. It is commonly used in solar PV, BESS, EV charging, building energy management and industrial distribution systems where compact single-phase metering and RS485 communication are required. Selected variants support Modbus RTU and DL/T 645-2007. The fast-refresh value refers to communication response time, not LCD refresh time or waveform sampling frequency.
