Digital active power meters are suitable for power grids and automation control systems, mainly measuring active power in the grid. According to their additional functions, they can be divided into X/K series of digital display instruments.
The X series intelligent digital active power meter is a digital power meter that calculates the active power value through direct AC sampling and software calculation, and displays it directly on the meter head digital tube (LED) or liquid crystal (LGD).
The K series intelligent digital active power meter 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, DGO-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;
The product complies with GB/T22264.1-2008/GB/T13978-20080
