The SDM630MCT-Lora is three phase LoRaWAN multi-function energy meter for IOT solutions.
With built-in LoraWAN module, it measures and displays the characteristics of single phase two wire (1p2w), single phsae three wire (1p3w), three phase three wire (3p3w), and three phase four wire(3p4w) supplies, including kWh, kVArh, kW, kVA, PF, frequency, voltage, current, demand, etc.
The requisite current input(S) are obtained via 1/5A output current transformers (CT), this meter can be configured to work with a wide range of CTs, giving the unit a wide range of opration. Configuration is password protected.
SDM630MCT-LoraWAN have been assessed and certified as meeting the requirements of EU Directive 2014/32/EU. The instrument traceable number is 0120/SGS0703.The meter is also ETL listed by intertek.
