The SDM230-Modbus is a RS485 Modbus/DLT645 100A Din Rail Single Phase MID Energy Meter. It measures active energy, reactive energy, current, voltage, power, power factor, frequency, etc. The units support Max. 100A direct connection, saving the cost and avoiding the trouble to connect external CTs. Two pulse outputs and 1 communication port (RS485 Modbus/DLT645) are provided for remote monitoring and setting, suitable for monitoring energy consumption in residential, solar PV, EV Charging system, industrial and utility applications.
The unit has been approved to meet the requirements of EU Directive 2014/32/EU.
