Designed for residential buildings, apartment complexes, and light commercial installations, it fits a standard 2-module DIN rail slot — half the width of a three-phase meter. LoRaWAN connectivity eliminates the need for data communication cabling, allowing a single gateway to collect readings from dozens or hundreds of meters across an entire building or residential complex at distances of up to several kilometres. Wireless data via LoRaWAN — no communication cabling needed Built-in relay — remote on/off control & prepaid management Multi-tariff T1–T4 — automatic time-of-use cost tracking Bidirectional metering — import & export, ideal for solar PV systems Compact 2-module width — saves DIN rail space One gateway covers entire building or complex — scalable deployment Max. current 80A direct connection (with relay) LoRaWAN wireless + RS485 Modbus RTU DIN rail TH35-7.5, 2-module width Multi-tariff T1–T4 time-of-use metering Built-in relay with 50 operation records Bidirectional energy metering (import/export) Monthly & daily consumption statistics Two-source switching and metering 1 passive pulse output (configurable) Touch key design LCD display with backlight Pulse constant: 1000 imp/kWh 1.
