Digital power factor meters are suitable for power grids and automation control systems, mainly measuring the power factor in the grid. According to their additional functions, they can be divided into two series of digital instruments: X and K.
The X series intelligent digital factor meter is a digital power meter that measures power factor directly through AC sampling and uses the true effective value algorithm, and is directly displayed by the digital tube (LED) or liquid crystal (LCD) on the meter head.
The K series power factor intelligent digital display instrument adds a variable ratio keyboard function on the basis of the X series. Optional functional modules include:
/C - 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, DCO-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;
