This digital panel voltmeter is applicable for electric power grid and automation control systems, mainly used to measure voltage in power grid. According to the additional functions, the meters can be divided into X, K series.
X series digital display intelligent voltmeters adopt direct AC sampling, use algorithm of True RMS to measure the voltage, and employ direct display of LED tube.
K series intelligent digital display meters are designed on the basis of X series, can be an optional of 1-3 channels of analog transmitting output (4-20mA,etc.) , 1-4 channels of digital input measuring function (realizing“remote signaling”) ,1-2 channels of relay output function (realizing “remote control”); and 1 channel of RS-485 digital interface, adopting Modbus-RTU protocol to realize “remote measurement” function, it is flexible and convenient to use and with three-row digital display or single-row digital display.
The meters also can be divided into single-phase voltage meter and three-phase voltage meter according to the measured power network,. Display mode of single-phase voltage meter is single-row digital display or liquid crystal display; Display mode of three-phase voltage meter are three-row digital display or liquid crystal display.
Detailed technical specifications refer to the technical indexes of digital display meter.
