Acrel Three-phase AC Multi-function Panel Energy Meter AMC72L-E4/KC

Overview AMC series intelligent power collection and monitoring device is a smart meter designed for power moni toring needs of power systems, industrial and mining enterprises, utilities, and intelligent buildings. It integrates measurement of power parameters (such as single-phase or three-phase current, voltage, and active power). Power, reactive power, apparent power, frequency, power factor) and power monitoring and assessment management. At the same time, it has a variety of peripheral interface functions for users to choose: with RS485 communication interface, MODBUS-RTU protocol can meet the needs of communication network management; 4-20mA analog output can correspond to measured electrical parameters, meet DCS Such interface requirements; with switch input and relay output can realize the function of “remote signal” and “remote control” of circuit breaker switch. High-brightness LED/LCD display interface, parameter setting and control through buttons, ideal for real-time power monitoring systems. Can directly replace conventional power transmitters and measuring instruments. As an intelligent, digital front-end acquisition component, the instrument has been widely used in various control systems, SCADA systems and energy management systems. Main Functions  Panel Overview  Main Parameters  Dimension  Wiring Illustration
