Product Description
Three-phase Programmable intelligent digital display meters are applied in electric power network and automatic control system, mainly measuring all the parameters in the power system, such as current, voltage, frequency, power factor, active power, reactive power and so on. In according to its additional functions, the meters can be divided into X, K, D, S four series.
X series of intelligent digital display meters, mainly measure and display the electrical parameters in the electric power network, such as current, voltage, power, frequency and power factor and so on, with the features of intuitive display, high precision, good reliability, anti-vibration, etc. AC True effective value measurement can be used to a serious wave distortion place.
On the basis of X series, K series intelligent digital display meters have added with the functions of setting ratio keyboard and one channel RS485 communication interface output(supports Modbus RTU protocol) in order to facilitate digital display meters in the group networking.
D series digital display transmission meters on the basis of X Series meters have added with the functions of analog transmitting output(4-20m A and so on) and one channel RS485 communication interface which supports Modbus-RTU protocol, and can be directly three lines digital display or single-line digital switch.
S series Digital alarm monitoring control meters have increased the functions of relay output (to achieve "the excess limit alarm or telecontrol function") on the basis of X series meters: RS485 digital interface which supports Modbus-RTU implement "remote" function, the variable ratio and communication parameters can be easily and momentarily set through meter panel buttons.
