Acrel AMC72L-E4 / KC Three Phase Multifunction AC Power Meter

Name: AMC72L-E4 / KC Three Phase Multifunction AC Power Meter
Brand: Jiangsu Acrel Electrical Manufacturing Co., LTD.

AMC series meters adopt AC sampling technology, which can measure the current ,voltage,power, power factor and electric energy parameters in the power grid separately.

It can set the magnification through the panel membrane switch. The meters have RS485 communication interface, adopt Modbus protocol; also can convert the power signal into a standard DC analog signal.
