1 Overview

The rail type multifunctional power instrument with external opening and closing transformer is suitable for energy-saving renovation projects in high energy consuming industries such as smelting, steel, welding, and semiconductor. It is also suitable for power monitoring and demand side management of distributed photovoltaic grid connected cabinets. It has the characteristics of no need to dismantle the busbar, simple and convenient wiring, safe construction, saving users renovation costs, and improving efficiency. It integrates the measurement of all power parameters (such as single-phase or three-phase current, voltage, active power, reactive power, apparent power, frequency, power factor) as well as energy monitoring and assessment management. At the same time, it has multiple peripheral interface functions for users to choose from: with RS485 communication interface, adopting MODBUS-RTU protocol to meet the needs of communication network management; With switch input and relay output, it can achieve the functions of "remote signaling" and "remote control" of circuit breaker switches. It adopts an LCD display interface and parameter setting and control are achieved through panel buttons, which is very suitable for real-time power monitoring systems.
