The meters adopt high accuracy AD chip and high reliability MCU design, 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. PD652Z has all functions of PD652E,but at the same time, it can be an optional of 1-4 channels of digital input and 1-4 channels of digital output and 1-4 channels of analog transmitting output (4-20mA,etc.) 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 front end of power grid, PD652E/Z 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 switchgears, 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.
