Energy meter SDM72D-M-2

The SDM72D-M-2 three-phase meter is designed to read electrical network parameters via the Modbus RTU bus.
Our Lan Controller series devices – LK3.5+, LK4, and LK4mini – support this meter, enabling integration with a remote monitoring system.

Unlike the older SDM72D-M version, the new SDM72D-M-2 offers access to a wider range of measurements. The unit measures and displays voltage, current, frequency, power factor, active power, reactive power, active energy, reactive energy, and more.
