- Product Introduction
Products Description
The Multi-functional 3 Phase energy Monitor is an intelligent device designed for programmable measurement, display, digital communication, and power pulse output. It performs comprehensive monitoring of three-phase electrical parameters-including current, voltage, active and reactive power, power factor, frequency, and energy consumption-while supporting real-time data display, acquisition, and transmission.
The on-site LED display and remote controller communicate via an RS-485 digital interface using the MODBUS-RTU protocol, enabling seamless system integration and remote access.
