AMC seres meters adopt AC sampling technology, which can measure the curent yvoltace,power, power factor and electric energy parameters in the power grioseparately. t can set the magnification through the panel membrane switch. The meters have RS485 communication interface, adopt Modbus protocol also canconvert the power signal into a standard DC analog signal.
