Digital Screen Display Meter

Application

Digital screen display meter can be used in the electrical power grid's automation control system, to measure every electricity, such as current, voltage, frequency, power factor, active power, reactive power, etc. By means of function, it can be divided into X series and S series digital screen display meter.

X series digital screen display meter, is to measure and display the electricity of current, voltage, frequency and power factor. It has advantages of parameter display intuitive, high precision, good stability, anti-vibration, etc, AC and DC RMS measurement, and can be used for the place seriously distorted.

S series of programmable digital alarm table is designed to measure and control current in power systems,industrial and mining enterprises and others. It can high-precision measure many commonly used power parameters such as three-phase voltage, three-phase current, three-phase voltage and current combined, three-phase active power, active power, reactive power and other power parameters. It has four switch measurement function(to achieve remote)and 2 relay output function(to achieve remote ) with RS-485 digital interface, using Modbus-RTU protocol, to achieve remote mail function. Variable ratio communication parameters can be set through the instrument panel keys with flexible and convenient usage.
