Description
Eastron SDM120CTM-40mA DIN Rail Energy Meter
The SDM120CTM-40mA is a compact 1-module (18mm) single-phase multifunction DIN rail energy meter. It provides precise measurement of key electrical parameters including active energy (kWh), reactive energy, voltage, current, power, power factor, frequency, and more.
Designed for use in residential, solar PV, industrial, and utility applications, the meter supports bi-directional energy monitoring, making it ideal for solar and other renewable energy systems.
The device operates with 40mA current transformers (CTs) and is compatible with a wide range of external CTs for flexible installation. It features 2 pulse outputs and Modbus RS485 communication for easy remote monitoring and system integration.
