Detailed specification:
PD561E and PD561Z series multifunction power meters are a kind of high accuracy, high reliability and high cost performance intelligent distribution meters that are especially 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 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, UIPO demand and bi-directional electric energy metering in the three-phase power grid, have standard electric energy pulse output and RS485 communication interface, with many optional extended function modules.
PD561E series (LED display) is a product with general functions, has measurement and metering functions, is equipped with electric energy pulse output and communication interface; PD561Z series (LCD display) adopts liquid crystal display and Chinese/English menu,has functions of multi-rate electric energy metering and automatic reading.
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, PD561E/Z series multifunction network monitoring meters have been widely applied to various control systems, SCADA systems, energy management systems, substation automation, distribution automation, residential powermonitoring 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
