SDM120CT Modbus / Mbus / Pulse

SINGLE PHASE MULTI-FUNCTION ENERGY METER

The SDM120CT-M 100mA is a SAA 100mA CT input Din Rail Single Phase Multi-function Solar PV /Zero Export Meter with RS485 output for PV metering. It measures active energy, reactive energy, current, voltage, power, power factor, frequency, etc. Two pulse outputs and 1 communication port 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.
