Product Description
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 voltmeter and three-phase voltmeter according to the measured power network,. Display mode of single-phase voltmeter is single-row digital display or liquid crystal
display; Display mode of three-phase voltmeter are three-row digital display or liquid crystal display.
Detailed technical specifications refer to the technical indexes of digital display meter.

FAQ
1,Q:Why your quotation is higher than some other suppliers?
A:In domestic market, the high and low quality brands are mixed together. There are many low-cost meter which is actually assembled with some cheaper and unstable parts, it crudely, to reduce costs and use of substandard components for assembly, there is a very big security risk! In order to protect the pro personal and property safety, please do not covet low price, be sure to choose a reliable meter!
..............................................................................................................................................................
2,Q:Your meter power supply is 220V,380V or other voltage?
A:Our meter power supply is normally 220V(240V)AC,50Hz,if you need 380Vac or AC/DC 80V-270V,then you It needs to be customzied.
