The SDM630MCT-MB is CT Operated Mbus Din Rail Three Phase UL Energy Meter. 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 1A/5A input CTs. Build-in interface provides pulse and Mbus RTU outputs.
SDM630MCT-MB has been assessed and certified as meeting the requirements of UL 61010.
