THREE PHASE MULTI-FUNCTION ENERGY METER
The SDM630MCT-MV is SAA CT Type Din Rail Three Phase Multi-function Solar PV /Zero Export Meter for PV metering. Suitable for monitoring energy consumption and many other electrical parameters. The unit requires auxiliary power supply (AC or DC) to power the meter and it can work with 333mV/100mV input CTs. Build-in interface provides pulse and RS485 Modbus RTU outputs. Its bi-directional measurement function made it a good choice for Solar PV and the Zero Export Systems.
