Acrel ADW300A Wireless IoT Energy Meter

General

AcrelADW300A wireless meter is primarily designed for measuring three-phase active power in low-voltage networks, featuring compact size, high accuracy, and comprehensive functionality. It supports multiple communication protocols including RS485, LoRa/LoRaWAN, 4G, and Wi-Fi, and includes an external current sampling mode for transformers, facilitating installation across various applications. The device can be flexibly installed within distribution boxes to meet requirements such as sub-metering of power consumption across different zones and loads, operation and maintenance monitoring, or overall power management.
