Three Phase Four WireSmart Electronics Energy Meter E3005-SA

A three-phase four-wire smart energy meter is an advanced metering device designed for three-phase four-wire power systems. It can simultaneously sample voltage and current of three phases, accurately measure active and reactive energy, and monitor essential electrical parameters. Compared with traditional meters, it integrates intelligent features such as data storage, remote communication, and anti-tampering, making it widely used in industrial, commercial, and residential electricity management.

Three phase four wire smart meter Feature

● Accurate Energy Measurement：Measures active energy, reactive energy, and total energy precisely to ensure accurate billing.

● Real-time Monitoring：LCD display provides real-time readings of voltage, current, power, power factor, and other operating parameters.

● Multi-tariff Billing：Supports time-of-use billing (peak, flat, valley), helping users optimize electricity costs.

● Remote Reading & Communication：Equipped with RS485, infrared, or wireless communication interfaces, allowing integration with centralized metering and monitoring systems.

● Event Recording & Alarming：Records and alarms abnormal events such as power outages, under-voltage, over-voltage, and reverse phase sequence.

● Anti-tamper Protection：Detects abnormal wiring, magnetic interference, and tampering attempts to ensure data reliability.

● Strong Environmental Adaptability：Wide operating temperature range (-25℃ to +70℃) and IP54 protection rating make it suitable for outdoor and harsh environments.
