Product Description

AT160 Digital Three Phase Digital Panel Meter is an ideal device for power monitoring. The instrument has the function of simultaneous measurement of current, voltage, frequency, active power, reactive power, apparent power, forward and reverse active power, forward and reverse reactive power, power factor, etc. in the power grid. It is suitable for the distributed detection of transformers, generator sets, capacitor sets and motors, as well as the on-site monitoring of power grids and automation control systems.
This series of multifunctional energy meters can replace many traditional analog or digital measuring instruments (such as ammeter, voltmeter, power meter, power factor meter, frequency meter, etc.), which can greatly reduce the system cost, facilitate field wiring and improve the reliability of the system. The multifunctional energy meter is equipped with a serial port, allowing connection to an open computer network; the application of Modbus communication protocol makes it easy for the computer to program settings or read data.
