ADW300A Multifunctional Wireless Energy Meter

Acrel is excited to introduce the new ADW300A multifunctional wireless energy meter. It supports external open-type CTs and Rogowski coils for flexible installation, enabling multi-scenario power monitoring and wireless meter reading.

The ADW300A integrates high-accuracy energy metering, full electrical parameter measurement, 15-minute energy freeze, phase-sequence auto-diagnosis, harmonics, TOU tariff and temperature / leakage / I-O expansion — with 4G / WiFi / LoRa / LoRaWAN wireless links and Bluetooth local commissioning. It also supports outage reporting, breakpoint resume and remote parameter configuration, making it an ideal choice for power supervision and O&M in industrial plants, distribution rooms, telecom base stations and commercial buildings.
