The SDM230 LoRa Mesh
is a new generation single phase multi function energy meter with wireless communication Lora module built inside. with Eastron lora gateway ESP-6 , the user can easily build a wireless meter reading system.
The Unit measures and displays the characteristics of single phase two wire(1P2W), single phase three wire (1P3W) networks. The measuring parameters include voltage (V), Current (A), Frequency (Hz), Power(kW/kVar/kVA), import/export/total energy(kWh/kVarh). The unit can also measures Max. demand current and power at preset period of up to 60 minutes.
