NGD-230 series three-phase liquid display electronic measuring instrument
High power quality requirement, harmonic analysis and applications need serious harmonic pollution three-phase liquid NGD-230 series electric measuring meter. It not only can measure all the power parameters, such as three-phase current, voltage, active power, reactive power of non electric degree, at the same time, with power quality analysis, billing, remote meter reading, most senior function value statistics and demand analysis and so on, so as to achieve a variety of electrical science tube.
Electric energy pulse output function
There are 2 switch output is on the two side active power and wattless power transmission output, pulse parameter is 6400,
Can be used to power the detection accuracy or electric energy pulse acquisition, the output is the optocoupler relay output.
Statistical function ·
The total harmonic distortion of phase line voltage rate (THD), three-phase current total harmonic distortion rate (THD); ·
2 ~ 31 times harmonic share three phase line voltage (Ua, Ub, Uc or Uab, Ubc, Uca);
2 ~ 31 times harmonic share three-phase current (Ia, Ib, Ic).
The switch quantity monitoring function
The largest can collect the state of the switch and a maximum of 4 kinds of state signal;
Relay output function
2 relay outputs;
Relay output mode can be selected from the hold mode (mode 1) and communication control mode (mode 2) two kinds of mode;
The above function is set up to meet the needs of various occasions to control;;
communication function
