1, overview:
WJ-2k4u/WJ-2k4i/2k4ui series multifunctional power meters are a kind of high accuracy, high reliability, and high-cost performance intelligent distribution meters that are specially designed for electric power systems, industrial and mining enterprises, communal facilities, smart buildings, and so on for the purpose of electric power monitoring, intelligent control, and measurement examination.
 
The meters can measure all-electric parameters such as three-phase voltage (phase/line), three-phase current, active power, reactive power, power factor, power system frequency, four-quadrant energy measurement, UIPO demand, and bi-directional electric energy metering in the three-phase power grid, have standard electric energy pulse output and RS485 communication interface.
 
This series of products has high-cost performance, can directly replace the conventional electric power transmitter, measurement, indicator meter, electric energy metering meter, and relevant auxiliary units. As an advanced intellectualized and digitized acquisition element in the front end of the power grid, PD652E series multifunction network monitoring meters have been widely applied to various, control systems, SCADA systems, energy management systems, substation automation, distribution automation, residential power monitoring and control systems, industrial automation, smart buildings, intelligent switchboards switchgear, etc., the meters have advantages of convenient installation, simple wiring, easy maintenance, small work amount, on-site programmable setting and input parameters, etc, and can carry out network building and communication with different PLC and industrial control computers.
