The Eastron SDM630-2T is a high-end three-phase multifunction energy meter suitable for accurate power measurement in industrial, commercial, and residential environments. It is designed for direct current measurement up to 100 A without the need for external current transformers and supports 3-phase 4-wire, 3-phase 3-wire, and single-phase 2-wire configurations.
The device enables detailed monitoring of all major electrical parameters: active, reactive, and apparent power (W, Var, VA), voltage, current, power factor (PF), frequency, total harmonic distortion (THD), maximum demand (DMD), and energy consumption in both import and export directions (including net kWh). It also supports dual source metering, making it ideal for hybrid systems.
A backlit LCD display with navigation buttons provides clear, on-site parameter visualization. Two passive pulse outputs allow data transmission to other monitoring systems. With its RS485 Modbus RTU interface, the meter is ready for integration into energy management systems, SCADA, or building automation platforms.
High accuracy, low internal power consumption, wide voltage range, and MID 2014/32/EU certification ensure suitability for billing applications and regulatory compliance.
