The AC Power Monitor is a solid state Power Meter. Monitoring of single phase AC supply including all types of energies. The AC Power Monitor is based on a dual micro controller , with a high degree of programmability. The Meter has been programmed to operate as an intelligent front end measuring and storing device & serial port connectivity qualifies model AC Power Meter. The Meter’s supplied preprogrammed for operation and can be directly installed. The Meter can be read manually or through a RS-485 MODBUS RTU Protocol.
