The SDM230 LoRa WAN MID
Single-phase electricity meter SDM230 LoRa WAN is a new generation single-phase multi-function electricity meter with wireless communication, the meter has been built Lora WAN module. Range up to 3 km.
The electricity meter can wirelessly send data to the nearest LoRa WAN gateway, or to an existing local LoRa WAN network.
The device measures and displays properties of single-phase two-wire (1P2W), single-phase three-wire (1P3W) networks. The measurement parameters include voltage (V), current (A), frequency (Hz), power (kW / kVar / kVA), import / export / total energy (kWh / kVarh).
Can be used for invoicing of energy consumtion due to the MID-certification.
