The SDM120CT-MV is a RS485 Modbus CT Type mV/mA input Single Phase Multi-function Energy Meter with RS485 Modbus/DLT645 output. It measures active energy, reactive energy, current, voltage, power, power factor, frequency, etc. Two pulse outputs and 1 communication port (RS485 Modbus/DLT645) are provided for remote monitoring and setting, popular with single phase PV solar power system. The meter can be configured to work with a wide range of CTs, giving the unit a wide range of operation.?
