Three phase power meter

Overview

AMC96L-E4/KCTBThree phase power meterIt can measure electrical parameters in a single-phase power grid, such as three-phase voltage, single-phase current, active power, reactive power, power factor, grid frequency, etc. It has bidirectional energy metering function and can measure harmonic content in the power grid. It can be widely used in substation automation, distribution automation, intelligent buildings, and internal energy measurement, management, and assessment of enterprises. The measurement accuracy is 0.5 level, and on-site display and remote RS-485 digital interface communication are achieved using the MODBUS-RTU communication protocol.

Three phase electricity meterIt is an electrical device used to measure and record the energy consumption in the power system. This type of electricity meter is usually installed on switchgear to monitor and control the use of electrical energy. It can also be equipped with various additional functions, such as remote meter reading, energy management, data collection, etc., to meet the needs of different users.
