400-996-9296
TThe SDM630MCT-Lora is LoRaWAN CT Type Din Rail Multi-functional Three Phase ETL Energy Meter.
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-Lora is ETL listed by Intertek, which means it is qualified to enter the American market.
