Digital reactive power meters are suitable for power grids and automation control systems, mainly measuring reactive power in the grid. According to their additional functions, they can be divided into X/K series of digital display instruments.
The X series energy and reactive power intelligent display instrument is a digital power meter that uses direct AC sampling, calculates the reactive power value through software, and displays it directly on the meter head digital tube (LED) or liquid crystal (LGD).
The K series reactive power intelligent digital display instrument adds a variable ratio keyboard function on the basis of the X series. Optional functional modules include:
/G-communication function (instrument data is directly displayed on the computer and can be printed out, RS485 communication interface, standard Modbus RTU protocol);
/M - Analog output (When the instrument is working, it can output one or three sets of isolated analog signals, which are linear with the displayed value. The output power is DC4-20mA, DCO-5V, DGO-10V;
J - Relay alarm output, two relay alarm outputs, the upper and lower line alarm values can be set freely.
/K-switch input/output (I/O) module;
