AMC series programmable intelligent meters, adopting AC sampling technology, can directly or indirectly measure the electric voltage and current of a single-phase or three-phase grid. It can be used for local display, and connecting industrial control devices to form measuring control systems.
This series of meters have an RS-485 port, adopting the Modbus-RTU protocol. Analog output, alarm output, and switching input/ output can be selected. Based on different requests, by pressing the keys, parameters of ratio, alarm, communication, etc. can be modified.
