WDS（T）300--A The intelligent electric power testing meter
General:
The intelligent electric power testing meter adopts large-scale integrated circuit,numerical sampling technique,and SMT.It was designed as a installation meter according to electric power testing requirement of power system,corporations,public service,intellective buildings;etc.
The meter has high ratio of performance to price,which can replace normal electric power transformer,testing indication meter,watt-hour meter and the relative auxiliary units.
It can be widely uesd in power management system,transformer substation automatization,distributive electrified line netting automatization,intellective buildings intellective distributive set,switch cabinet.It can be easily installated connected and maintained.It can be also input parameter through program setting in the scene,and be compatible with different PLC as well as industrial PC communication software.
Main Function
■It can measure all the normal electrical parameter accurately,such as voltage,currency,active power,reactive power,frequency,power factor,multi-rate,reactive four quadrantal electric power,etc.
■It adopts high brightness LED,LCD display to show metrical parameter and operation information of electrified wire netting system.Panel of the meter has four key-press of program,so the customers can realize display transformer easily in the scene and meter parameter setting,which is very flexible.
■RS485 modbus-RTU and modbus-ASCII communication agreement can be compatible with all kinds of PLC,industrial PC communication software.
■Electric power impluse output of 2 circuits.
■Simulation output of 4 circuits realizes the transformer output of electic power.
