Intelligent comprehensive electric parameter meter is designed by the electric power intelligent monitoring and electric 

energy metering referenace and other demands of electric power system, industrial and mining enterprises, public facilities, 

intelligent buildings and other, it is adopted by large scale integrated circuit, it can measure and work out all items of electric 

power parameters by the alternating current sampling algorithm, moreover, it can make a high-precision measurement for all 

the common electric power parameters, three-phase voltage, three-phase current, active power, reactive power, apparent power, 

frequency, power factor, four quadrant electrical energy, accumulated active/ reactive electrical energy, switching value input 

monitoring, and 2-31 times harmonic wave components in the three-phase power grid, the meter has the communication 

interface, relay output control, electrical energy pulse output and other functions.

Intelligent comprehensive electric parameter meter has many kinds of extended function for choosing: 2 circuits RS485 

communication interface, 4 circuits relay output, local or remote switching signal monitoring and control output function 

(“remote control” function), pulse output; it can be programmed as alarm signal output or other control signal output. Intelligent 

comprehensive electric parameter meter has extreme performance performance-cost ratio, which can directly replace the 

conventional electric transmitters, measuring indicators, electric energy meters and the relevant auxiliary units. As a kind of 

advanced intelligent, digitized power grid front-end acquisition element, it is widely applied in all types of control systems, 

SCADA systems and energy management systems, substation automation, distribution grid automation, housing estate power 

monitoring, industrial automation, intelligent buildings, intelligent switchboards and switch cabinets, its characteristics show 

convenient installation, easy wiring, simple maintenance and small quantities, it can program the input parameter, complete the 

networking of industry different PLC and industrial control computer communication software on the field.
