Acrel AMC72L-E4/KC Multifunction AC Power Meter

Name: AMC72L-E4/KC Multifunction AC Power Meter
Brand: Jiangsu Acrel Micro-grid Research & Development Institute

AMC72L-E4/KC Multi-function AC Power Meter integrates the measurement of electric parameters (current, voltage, active power, reactive power, apparent power, frequency, power factor), as well as power monitoring and assessment management. It also has RS485 communication to meet the needs of communication network management. The 4-20mA analog output can correspond to the measured electrical parameters to meet the interface requirements of DCS. The meter with digital input and relay output can realize "remote signaling" and "remote controlling" functions of circuit breaker switch.
