ADW310 is a 1-phase DIN-rail wireless IoT energy meter engineered for real-time active energy, voltage, current, power, PF & frequency logging in 85-265 VAC networks.
With embedded 4G LTE, Wi-Fi, NB-IoT, LoRaWAN plus Modbus-RTU RS485, it streams encrypted data directly to any MQTT cloud, SCADA, EMS or billing portal without gateways .
It supports split-core CTs for 100 A loads, and offers anti-tamper cover, 8-digit LCD, 1-pulse output and 3-key configuration. Built-in RTC, TOU tariff registers and 30-day load profiles enable smart-grid applications, solar net-metering, EV charging analytics, smart-building sub-metering and utility AMI rollouts while complying with IEC 62053-21 & CE.
