The SDM54 is a 3 Modules Dual Tariff RS485 Din Rail Three Phase Multi-function Energy Meter with backlit LCD display. It replaces 2 energy meter recording data from two different sources of energy. It provides two counters showing energy consumption on public electricity board (EB) and diesel generator (DG). The meter measures all important electrical parameters including 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.
