EASTRON SDM630-Modbus V3 Three-Phase Energy Meter MID (32106)

With direct connection up to 100 A and MID certification, the EASTRON SDM630-Modbus V3 is a three-phase energy meter built for precise submetering and building automation. It measures active and reactive energy, power, voltage, current, frequency, and power factor on a backlit LCD, and communicates via Modbus RTU over RS485.

Overview

The SDM630-Modbus V3 is a DIN rail mounted three-phase energy meter with direct current measurement up to 100 A. It supports both 3-phase 4-wire and 3-phase 3-wire configurations, making it suitable for a wide range of low-voltage installations. The meter is MID certified (Module B + D), which allows its use in billing applications within the EU. It features a backlit LCD display for clear reading of all measured parameters, and two pulse outputs that can be configured for kWh or kVArh.
