Three Phase Four Wire Multi-tariff CT- operated Smart Energy Meter
INX451 Three Phase Four Wire Multi-tariff GPRS Energy Meter is one type compact Three Phase smart meter, which provides a cost effective solution for commercial and industrial applications. It is used to measure active forward and reverse energy, reactive energy in four quadrants with TOU along with active and reactive M.D. It can also measure and monitor power parameters such as Active power, Reactive power, Voltage, Current, Power Factor and Frequency in real time. The meter has additional features such as Remote GPRS / GSM Communication, TOU, Load Profile, Data Storage, Event Log, Tamper Resistance, Infra-red Communication etc. The meter is designed and manufactured with modern metering technology, using advanced ultra-low power consumption LSI technology and SMT manufacturing process.
